[Music]

3
00:00:12,500 --> 00:00:17,100
and welcome back to the second Talk of

4
00:00:16,199 --> 00:00:19,380
the

5
00:00:17,100 --> 00:00:22,619
day

6
00:00:19,380 --> 00:00:27,480
um this time around we have Peter Niche

7
00:00:22,619 --> 00:00:30,300
and he's able to help our Alex lamb

8
00:00:27,480 --> 00:00:32,160
um Peter is from he's a data nerd

9
00:00:30,300 --> 00:00:33,780
describes himself as darned who works in

10
00:00:32,160 --> 00:00:37,140
higher education

11
00:00:33,780 --> 00:00:39,180
he's a Committee Member of the Wikimedia

12
00:00:37,140 --> 00:00:42,300
Australia committee

13
00:00:39,180 --> 00:00:46,700
and today he's going to give you a talk

14
00:00:42,300 --> 00:00:50,460
about the wiki data which organizes the

15
00:00:46,700 --> 00:00:52,020
infrastructure behind Wikipedia please

16
00:00:50,460 --> 00:00:53,900
um

17
00:00:52,020 --> 00:00:55,620
introduce him thank you

18
00:00:53,900 --> 00:00:59,820
[Applause]

19
00:00:55,620 --> 00:01:01,920
foreign thank you yes and Alex Lam is

20
00:00:59,820 --> 00:01:04,559
also from Wikimedia Australia he's

21
00:01:01,920 --> 00:01:07,040
currently our secretary so

22
00:01:04,559 --> 00:01:11,040
um yeah today we're going to talk about

23
00:01:07,040 --> 00:01:12,119
wikidata the way we'll do this is

24
00:01:11,040 --> 00:01:15,420
um basically I'll give you a quick

25
00:01:12,119 --> 00:01:16,860
outline of Wiki data what it is how it

26
00:01:15,420 --> 00:01:18,479
works

27
00:01:16,860 --> 00:01:20,640
um just a little bit of a general

28
00:01:18,479 --> 00:01:22,439
introduction and then Alex who's

29
00:01:20,640 --> 00:01:24,299
probably the real expert we'll take you

30
00:01:22,439 --> 00:01:26,400
through just some examples and dive into

31
00:01:24,299 --> 00:01:28,680
stuff in a bit more depth and we'll have

32
00:01:26,400 --> 00:01:32,240
some time at the end for questions so

33
00:01:28,680 --> 00:01:32,240
very happy to take those

34
00:01:32,280 --> 00:01:37,579
so what is wikidata

35
00:01:35,180 --> 00:01:41,540
wikidata.org is the place to go but

36
00:01:37,579 --> 00:01:44,640
wikidata is an open free

37
00:01:41,540 --> 00:01:48,000
multi-lingual database and that supports

38
00:01:44,640 --> 00:01:51,060
Wiki media projects so it was launched

39
00:01:48,000 --> 00:01:53,759
in 2012 so it's over 10 years old now

40
00:01:51,060 --> 00:01:55,799
this is an example of a page that you'll

41
00:01:53,759 --> 00:01:59,399
see but I'll go through in a bit more

42
00:01:55,799 --> 00:02:01,920
detail about how wikidata is structured

43
00:01:59,399 --> 00:02:05,280
how how it's organized

44
00:02:01,920 --> 00:02:05,880
what all these things mean so

45
00:02:05,280 --> 00:02:09,300
um

46
00:02:05,880 --> 00:02:11,900
just briefly the origins of Wiki data so

47
00:02:09,300 --> 00:02:15,180
a bit like Wikipedia

48
00:02:11,900 --> 00:02:16,860
in Wikipedia we have many wikipedias

49
00:02:15,180 --> 00:02:18,959
most people will be familiar with the

50
00:02:16,860 --> 00:02:22,080
English Wikipedia But there are many

51
00:02:18,959 --> 00:02:24,660
many different wikipedias and initially

52
00:02:22,080 --> 00:02:26,340
when it was set up if you wanted to put

53
00:02:24,660 --> 00:02:27,599
a photo up you had to actually put that

54
00:02:26,340 --> 00:02:30,020
photo

55
00:02:27,599 --> 00:02:33,000
repeatedly in each of those different

56
00:02:30,020 --> 00:02:34,260
wikipedias and so

57
00:02:33,000 --> 00:02:36,480
um

58
00:02:34,260 --> 00:02:39,180
the way this was solved or to address

59
00:02:36,480 --> 00:02:41,700
this problem this kind of redundancy was

60
00:02:39,180 --> 00:02:43,440
that we create they created our Wiki

61
00:02:41,700 --> 00:02:46,739
media Commons

62
00:02:43,440 --> 00:02:49,099
which acts as a repository of media that

63
00:02:46,739 --> 00:02:52,440
all different languaged

64
00:02:49,099 --> 00:02:54,239
wikipedias could draw on

65
00:02:52,440 --> 00:02:56,160
so there's a similar problem with data

66
00:02:54,239 --> 00:02:58,920
so you will have seen these data boxes

67
00:02:56,160 --> 00:03:01,440
in Wikipedia and these had to be done

68
00:02:58,920 --> 00:03:06,780
again individually in each different

69
00:03:01,440 --> 00:03:09,300
language of Wikipedia so wikidata was

70
00:03:06,780 --> 00:03:12,120
created to help with that so it's really

71
00:03:09,300 --> 00:03:14,580
a central data repository that all the

72
00:03:12,120 --> 00:03:16,500
languages could draw on you could change

73
00:03:14,580 --> 00:03:18,720
it in one place it would propagate to

74
00:03:16,500 --> 00:03:20,580
all the different wikipedias quite

75
00:03:18,720 --> 00:03:23,459
sensible

76
00:03:20,580 --> 00:03:25,760
so and the way it's structured is very

77
00:03:23,459 --> 00:03:28,980
much around linked open data principles

78
00:03:25,760 --> 00:03:32,879
so and I'll talk a bit more about that

79
00:03:28,980 --> 00:03:37,140
as we go in but basically all of Wiki

80
00:03:32,879 --> 00:03:39,860
data is public domain cc0 freely

81
00:03:37,140 --> 00:03:43,260
searchable we'll have a look at that

82
00:03:39,860 --> 00:03:46,920
unique permanent identifiers and they

83
00:03:43,260 --> 00:03:50,580
link out to other other databases

84
00:03:46,920 --> 00:03:54,060
so in terms of identifiers the basis of

85
00:03:50,580 --> 00:03:56,459
this in wikidata is the qid Q doesn't

86
00:03:54,060 --> 00:03:59,519
really have any great meaning it's just

87
00:03:56,459 --> 00:04:03,599
it's just what it's called but each item

88
00:03:59,519 --> 00:04:06,560
or each entity in wikidata has a qid and

89
00:04:03,599 --> 00:04:06,560
here are some examples

90
00:04:06,900 --> 00:04:14,159
the way the information is constructed

91
00:04:09,299 --> 00:04:17,000
is around like a a triple store it's a

92
00:04:14,159 --> 00:04:20,400
it's a database of

93
00:04:17,000 --> 00:04:22,680
relating entities together so in Wiki

94
00:04:20,400 --> 00:04:26,580
day we talk about them in terms of items

95
00:04:22,680 --> 00:04:28,020
properties and values so things like you

96
00:04:26,580 --> 00:04:31,680
know Perth is the capital of Western

97
00:04:28,020 --> 00:04:35,280
Australia Perth was you know came into

98
00:04:31,680 --> 00:04:38,699
being in 1829 in terms of that entity

99
00:04:35,280 --> 00:04:40,680
and also Perth was named after Perth so

100
00:04:38,699 --> 00:04:43,080
that's not a particularly helpful

101
00:04:40,680 --> 00:04:43,620
statement but we have

102
00:04:43,080 --> 00:04:46,259
um

103
00:04:43,620 --> 00:04:49,860
in terms of Wiki data we talk about that

104
00:04:46,259 --> 00:04:53,160
in terms of using those IDs so they have

105
00:04:49,860 --> 00:04:54,600
an ID and then the property of that ID

106
00:04:53,160 --> 00:04:57,840
so

107
00:04:54,600 --> 00:05:00,000
um is the capital of and then

108
00:04:57,840 --> 00:05:02,639
the thing that is the value is actually

109
00:05:00,000 --> 00:05:04,800
another item itself so it could be

110
00:05:02,639 --> 00:05:06,660
something literal it could be a date or

111
00:05:04,800 --> 00:05:08,460
a string but in this case it's another

112
00:05:06,660 --> 00:05:10,979
item itself

113
00:05:08,460 --> 00:05:13,680
and in terms of Perth being named after

114
00:05:10,979 --> 00:05:16,380
Perth well you've got the identifier to

115
00:05:13,680 --> 00:05:19,979
disambiguate things you also have

116
00:05:16,380 --> 00:05:21,840
descriptions and aliases that are behind

117
00:05:19,979 --> 00:05:24,320
that so

118
00:05:21,840 --> 00:05:27,240
you can see that one is capital Western

119
00:05:24,320 --> 00:05:30,780
Australia another one is Perth in

120
00:05:27,240 --> 00:05:32,039
Scotland and they have those different

121
00:05:30,780 --> 00:05:34,919
IDs

122
00:05:32,039 --> 00:05:36,479
and those description and aliases are

123
00:05:34,919 --> 00:05:39,900
also available in different languages

124
00:05:36,479 --> 00:05:41,820
all in the one place so when that data

125
00:05:39,900 --> 00:05:44,340
is pulled it can be pulled in any of

126
00:05:41,820 --> 00:05:47,280
those different languages hugely hugely

127
00:05:44,340 --> 00:05:51,500
time saving and quite valuable in terms

128
00:05:47,280 --> 00:05:51,500
of creating a Global Knowledge base

129
00:05:51,780 --> 00:05:57,000
in terms of

130
00:05:54,360 --> 00:05:58,979
those identifiers

131
00:05:57,000 --> 00:06:02,539
properties and values they can be

132
00:05:58,979 --> 00:06:05,280
qualified so for example

133
00:06:02,539 --> 00:06:06,560
Grace Hopper of pioneer computer

134
00:06:05,280 --> 00:06:09,060
scientist

135
00:06:06,560 --> 00:06:12,300
her given name

136
00:06:09,060 --> 00:06:16,520
do I have a pointer can you see it

137
00:06:12,300 --> 00:06:19,680
yeah so give a name over there

138
00:06:16,520 --> 00:06:22,680
is Grace and

139
00:06:19,680 --> 00:06:24,060
um so you can also

140
00:06:22,680 --> 00:06:27,000
um

141
00:06:24,060 --> 00:06:30,060
her family name change so there is a

142
00:06:27,000 --> 00:06:32,940
qualifier here of a start time so

143
00:06:30,060 --> 00:06:35,400
properties and values can be qualified

144
00:06:32,940 --> 00:06:38,160
in different ways and we'll probably see

145
00:06:35,400 --> 00:06:40,440
other examples of that as well so

146
00:06:38,160 --> 00:06:43,440
another example you know it's just

147
00:06:40,440 --> 00:06:47,759
educated at these different places and

148
00:06:43,440 --> 00:06:49,340
they have a start time an end time a

149
00:06:47,759 --> 00:06:51,539
major so

150
00:06:49,340 --> 00:06:54,300
properties and statements can be

151
00:06:51,539 --> 00:06:56,580
qualified in that way

152
00:06:54,300 --> 00:06:58,740
another really powerful thing about

153
00:06:56,580 --> 00:06:59,280
wikidata is that

154
00:06:58,740 --> 00:07:02,699
um

155
00:06:59,280 --> 00:07:06,139
although each each item has an

156
00:07:02,699 --> 00:07:08,940
identifier in this case grasshopper is

157
00:07:06,139 --> 00:07:11,900
q11641 we also bring in other

158
00:07:08,940 --> 00:07:14,000
identifiers from other well-known

159
00:07:11,900 --> 00:07:14,580
reputable sources so

160
00:07:14,000 --> 00:07:15,660
[Music]

161
00:07:14,580 --> 00:07:19,800
um

162
00:07:15,660 --> 00:07:23,460
via VIA Disney all different identifiers

163
00:07:19,800 --> 00:07:25,759
there are if you go to a Wiki P Wiki

164
00:07:23,460 --> 00:07:28,020
Data Page there are you know often

165
00:07:25,759 --> 00:07:30,060
dozens you know of these different

166
00:07:28,020 --> 00:07:31,979
identifiers and it's a really good way

167
00:07:30,060 --> 00:07:35,520
of being able to disambiguate and

168
00:07:31,979 --> 00:07:38,759
connect up those identifiers in a real

169
00:07:35,520 --> 00:07:42,020
linked data manner

170
00:07:38,759 --> 00:07:45,259
so yeah so they're the um virtual

171
00:07:42,020 --> 00:07:47,940
International Authority file and the

172
00:07:45,259 --> 00:07:51,180
biblio technician Elder France they can

173
00:07:47,940 --> 00:07:53,280
be both connected through this um

174
00:07:51,180 --> 00:07:55,460
through this qualifier through this

175
00:07:53,280 --> 00:07:59,759
property

176
00:07:55,460 --> 00:08:03,060
just like Wikipedia these things can be

177
00:07:59,759 --> 00:08:05,880
referenced so that reference can be a

178
00:08:03,060 --> 00:08:06,479
URL it can be just like Wikipedia

179
00:08:05,880 --> 00:08:09,560
um

180
00:08:06,479 --> 00:08:12,240
things in Wiki day to get reference and

181
00:08:09,560 --> 00:08:14,880
there can be more than one reference as

182
00:08:12,240 --> 00:08:17,580
well so in this case

183
00:08:14,880 --> 00:08:22,620
where Grace was educated yeah there's

184
00:08:17,580 --> 00:08:24,960
three references there so again

185
00:08:22,620 --> 00:08:30,319
just like Wikipedia collaboratively done

186
00:08:24,960 --> 00:08:30,319
all by volunteers people putting this in

187
00:08:30,419 --> 00:08:35,279
um we talk about

188
00:08:31,919 --> 00:08:36,719
um instances and subclasses so the data

189
00:08:35,279 --> 00:08:39,240
model is

190
00:08:36,719 --> 00:08:43,440
um again it's it's

191
00:08:39,240 --> 00:08:46,440
um it's been discussed and built up in a

192
00:08:43,440 --> 00:08:48,600
community-based way so here's an example

193
00:08:46,440 --> 00:08:52,220
of the big Merino if anyone's seen it

194
00:08:48,600 --> 00:08:54,440
but it's an instance of a big thing

195
00:08:52,220 --> 00:08:58,080
and an instance

196
00:08:54,440 --> 00:08:59,880
also an instance of a sculpture so you

197
00:08:58,080 --> 00:09:02,339
can have you know you don't have to

198
00:08:59,880 --> 00:09:06,060
restrict things to us a central kind of

199
00:09:02,339 --> 00:09:09,300
taxonomy but giving things instances and

200
00:09:06,060 --> 00:09:12,180
subclasses allows you to do quite

201
00:09:09,300 --> 00:09:14,399
interesting kind of modules so and

202
00:09:12,180 --> 00:09:17,880
querying so a big thing being a subclass

203
00:09:14,399 --> 00:09:21,240
of a Roadside Attraction and a sculpture

204
00:09:17,880 --> 00:09:22,680
is a subclass of a visual artwork so

205
00:09:21,240 --> 00:09:25,339
um

206
00:09:22,680 --> 00:09:25,339
yeah

207
00:09:28,680 --> 00:09:32,940
so I just probably wanted to talk about

208
00:09:30,899 --> 00:09:34,620
just before I hand over to Alex

209
00:09:32,940 --> 00:09:36,779
um just a little bit about

210
00:09:34,620 --> 00:09:38,040
sustainability because I think this is

211
00:09:36,779 --> 00:09:40,680
one of the real

212
00:09:38,040 --> 00:09:42,240
um real selling points of Wiki data I

213
00:09:40,680 --> 00:09:44,940
suppose is

214
00:09:42,240 --> 00:09:47,399
um it's it's having an actual you know

215
00:09:44,940 --> 00:09:50,279
we've all seen kind of Wikipedia and how

216
00:09:47,399 --> 00:09:53,580
that works but having Wiki data as a

217
00:09:50,279 --> 00:09:54,899
very powerful database the Wikimedia

218
00:09:53,580 --> 00:09:57,180
Foundation

219
00:09:54,899 --> 00:09:59,399
um you know sits behind all these

220
00:09:57,180 --> 00:10:00,839
different projects so not just Wikipedia

221
00:09:59,399 --> 00:10:02,940
there's

222
00:10:00,839 --> 00:10:06,540
um you know dozens of different projects

223
00:10:02,940 --> 00:10:09,240
that they support and as Wikimedia

224
00:10:06,540 --> 00:10:12,240
Australia we do a small part to kind of

225
00:10:09,240 --> 00:10:15,540
promote this as well and and help but

226
00:10:12,240 --> 00:10:18,140
there are um many many different Wiki

227
00:10:15,540 --> 00:10:21,620
Wikimedia projects

228
00:10:18,140 --> 00:10:25,860
they're funded they're run by volunteers

229
00:10:21,620 --> 00:10:28,019
they're collaborative so in terms of um

230
00:10:25,860 --> 00:10:31,620
you know putting together knowledge

231
00:10:28,019 --> 00:10:34,500
about entities it's a very it's a very

232
00:10:31,620 --> 00:10:36,839
good place to put things if you want

233
00:10:34,500 --> 00:10:40,500
um that information to persist into the

234
00:10:36,839 --> 00:10:42,060
future so if you're kind of um you know

235
00:10:40,500 --> 00:10:45,720
if your thing is

236
00:10:42,060 --> 00:10:46,560
um you know Botanical illustrations or

237
00:10:45,720 --> 00:10:49,440
it's

238
00:10:46,560 --> 00:10:51,360
um you know ancient relics or something

239
00:10:49,440 --> 00:10:53,519
and you want to create a website about

240
00:10:51,360 --> 00:10:56,160
that that's great but if you put it into

241
00:10:53,519 --> 00:10:59,579
Wiki data as well you can do that

242
00:10:56,160 --> 00:11:03,660
communally with other people it's backed

243
00:10:59,579 --> 00:11:05,880
by wikidata people can work on it I

244
00:11:03,660 --> 00:11:07,620
think yeah it's it's a really good thing

245
00:11:05,880 --> 00:11:09,300
to consider if

246
00:11:07,620 --> 00:11:11,100
um you're kind of dealing that sort of

247
00:11:09,300 --> 00:11:14,220
information

248
00:11:11,100 --> 00:11:16,680
so I will hand over to Alex who's going

249
00:11:14,220 --> 00:11:19,800
to kind of run through a few actual

250
00:11:16,680 --> 00:11:21,120
practical demonstrations about wikidata

251
00:11:19,800 --> 00:11:23,720
thanks

252
00:11:21,120 --> 00:11:23,720
Peter

253
00:11:28,440 --> 00:11:34,320
so as Peter mentioned

254
00:11:31,279 --> 00:11:37,920
wikiwikidata.org is the uh the site the

255
00:11:34,320 --> 00:11:40,380
main web interface of wikidata and um

256
00:11:37,920 --> 00:11:42,600
you know it looks looks quite similar to

257
00:11:40,380 --> 00:11:45,300
Wikipedia same colors uh you know

258
00:11:42,600 --> 00:11:47,880
sidebar of all the the links you can go

259
00:11:45,300 --> 00:11:49,680
to uh and a search search box at the top

260
00:11:47,880 --> 00:11:51,839
and and your you know if you set up an

261
00:11:49,680 --> 00:11:53,880
account like Wikipedia you don't have to

262
00:11:51,839 --> 00:11:55,820
set up an account but it's recommended

263
00:11:53,880 --> 00:11:59,279
that you do just means you can you're

264
00:11:55,820 --> 00:12:00,899
what you do is is logged and uh and

265
00:11:59,279 --> 00:12:02,880
tracked in your your history of

266
00:12:00,899 --> 00:12:05,700
contributions and people can contact you

267
00:12:02,880 --> 00:12:07,380
if they need to if you don't log in you

268
00:12:05,700 --> 00:12:09,079
can still make changes but it will log

269
00:12:07,380 --> 00:12:11,700
to IP address

270
00:12:09,079 --> 00:12:13,740
and um that you're that you're working

271
00:12:11,700 --> 00:12:16,680
on so you can set up an account it can

272
00:12:13,740 --> 00:12:18,360
be anonymous like Wikipedia uh it can be

273
00:12:16,680 --> 00:12:22,860
completely Anonymous you can see them

274
00:12:18,360 --> 00:12:26,040
some main numbers there one 102 million

275
00:12:22,860 --> 00:12:28,560
and nearly two hundred thousand data

276
00:12:26,040 --> 00:12:30,120
items so obviously that's way bigger

277
00:12:28,560 --> 00:12:31,860
than Wikipedia and and I think that's

278
00:12:30,120 --> 00:12:35,399
one thing that it's key to point out

279
00:12:31,860 --> 00:12:37,500
although Wiki data started as a

280
00:12:35,399 --> 00:12:40,980
um I guess a way of structuring or

281
00:12:37,500 --> 00:12:42,959
structuring data for Wikipedia as Peter

282
00:12:40,980 --> 00:12:45,240
mentioned it also ties into all those

283
00:12:42,959 --> 00:12:48,180
other projects that of the the Wikimedia

284
00:12:45,240 --> 00:12:49,920
Foundation runs Wikimedia Commons and

285
00:12:48,180 --> 00:12:51,959
and all the language editions of

286
00:12:49,920 --> 00:12:53,820
Wikipedia

287
00:12:51,959 --> 00:12:54,899
and so that means that wikidata is

288
00:12:53,820 --> 00:12:56,339
becoming

289
00:12:54,899 --> 00:12:59,519
um you know sort of kind of outgrowing

290
00:12:56,339 --> 00:13:01,079
its wiki Wikipedia Origins

291
00:12:59,519 --> 00:13:03,600
um and it's actually you know becoming a

292
00:13:01,079 --> 00:13:04,560
really um sort of amazing and useful

293
00:13:03,600 --> 00:13:08,820
um

294
00:13:04,560 --> 00:13:11,040
uh tool in the whole linked open data

295
00:13:08,820 --> 00:13:13,440
um in the world of linked open data

296
00:13:11,040 --> 00:13:14,940
and like Wikipedia anyone can edit it as

297
00:13:13,440 --> 00:13:18,360
I said you can you know just create an

298
00:13:14,940 --> 00:13:20,339
account or you can even edit anonymously

299
00:13:18,360 --> 00:13:22,380
so as I said this is the web interface

300
00:13:20,339 --> 00:13:24,260
there's a search box here it's quite

301
00:13:22,380 --> 00:13:27,660
powerful it uses elasticsearch I believe

302
00:13:24,260 --> 00:13:28,380
as Peter mentioned you can have

303
00:13:27,660 --> 00:13:30,480
um

304
00:13:28,380 --> 00:13:32,040
several items with the same name such as

305
00:13:30,480 --> 00:13:34,100
the examples of the Perth in Western

306
00:13:32,040 --> 00:13:36,959
Australia and the Perth in Scotland

307
00:13:34,100 --> 00:13:39,060
and but as you saw when Peter showed you

308
00:13:36,959 --> 00:13:42,360
there that each item or it's page in

309
00:13:39,060 --> 00:13:43,740
wikidata or item has a description and

310
00:13:42,360 --> 00:13:45,240
that description can be used to

311
00:13:43,740 --> 00:13:48,480
disambiguate and that's quite different

312
00:13:45,240 --> 00:13:50,100
to how Wikipedia does it Wikipedia you

313
00:13:48,480 --> 00:13:52,079
can't have two articles on Wikipedia

314
00:13:50,100 --> 00:13:53,940
with the same name and so you have to do

315
00:13:52,079 --> 00:13:56,700
disambiguation so you might have to have

316
00:13:53,940 --> 00:13:58,380
Perth comma Western Australia or Perth

317
00:13:56,700 --> 00:14:00,240
in bracket City in Scotland or something

318
00:13:58,380 --> 00:14:02,040
like that however Wicked out is quite

319
00:14:00,240 --> 00:14:03,839
different you can have two items with

320
00:14:02,040 --> 00:14:05,940
the same name or multiple items with the

321
00:14:03,839 --> 00:14:07,620
same name but um it's the description

322
00:14:05,940 --> 00:14:09,480
which which tells them apart so let's

323
00:14:07,620 --> 00:14:11,100
have a look at that Perth example I'll

324
00:14:09,480 --> 00:14:14,240
type Perth in and you can see there's a

325
00:14:11,100 --> 00:14:17,820
whole lot of results come up

326
00:14:14,240 --> 00:14:19,680
the wa West Perth is the first one the

327
00:14:17,820 --> 00:14:20,899
Scottish ones the second one and there's

328
00:14:19,680 --> 00:14:23,700
also some other

329
00:14:20,899 --> 00:14:25,200
parishes and places called Perth and

330
00:14:23,700 --> 00:14:29,720
including the suburb which I guess is

331
00:14:25,200 --> 00:14:29,720
the Central City CBD suburb

332
00:14:30,060 --> 00:14:33,240
so you just click on the one that you

333
00:14:31,380 --> 00:14:34,440
want there's there's more if uh if

334
00:14:33,240 --> 00:14:35,459
there's something with if there's a lot

335
00:14:34,440 --> 00:14:38,160
more examples

336
00:14:35,459 --> 00:14:40,380
so Peter showed you the the label which

337
00:14:38,160 --> 00:14:42,180
is what appears at the top there it is a

338
00:14:40,380 --> 00:14:44,459
speed Dimension completely multilingual

339
00:14:42,180 --> 00:14:45,959
there's about 300 languages that you can

340
00:14:44,459 --> 00:14:48,360
potentially put in labels and

341
00:14:45,959 --> 00:14:50,279
descriptions for it can be used for

342
00:14:48,360 --> 00:14:52,940
translation you could if you can you can

343
00:14:50,279 --> 00:14:57,000
use the API the search tools to actually

344
00:14:52,940 --> 00:14:59,639
translate terms or place names or from

345
00:14:57,000 --> 00:15:01,100
from one kind of text to another or

346
00:14:59,639 --> 00:15:03,600
another language

347
00:15:01,100 --> 00:15:05,339
as you can see the Korean there's no

348
00:15:03,600 --> 00:15:06,959
description there so there are there are

349
00:15:05,339 --> 00:15:08,519
quite a few gaps and it's all you know

350
00:15:06,959 --> 00:15:11,339
being built as Peter mentioned this is

351
00:15:08,519 --> 00:15:13,019
all being done by volunteers so uh

352
00:15:11,339 --> 00:15:16,940
people are sort of filling in these um

353
00:15:13,019 --> 00:15:16,940
these gaps as they as they find them

354
00:15:17,339 --> 00:15:21,480
um so as I mentioned there's four

355
00:15:19,139 --> 00:15:24,360
languages there English Korean Russian

356
00:15:21,480 --> 00:15:27,060
and Maori but there's as I said there's

357
00:15:24,360 --> 00:15:28,920
about 300 other 300 languages in total

358
00:15:27,060 --> 00:15:30,480
and you can you can click on that to see

359
00:15:28,920 --> 00:15:33,240
all the ones that have information put

360
00:15:30,480 --> 00:15:34,560
in or you can click on the uh the word

361
00:15:33,240 --> 00:15:36,600
English up there next to your account

362
00:15:34,560 --> 00:15:38,880
name and you can actually go to it and

363
00:15:36,600 --> 00:15:40,500
see the um

364
00:15:38,880 --> 00:15:43,160
um yeah the list of all the languages

365
00:15:40,500 --> 00:15:43,160
that there are

366
00:15:43,519 --> 00:15:48,779
this is a gadget that I've installed

367
00:15:46,980 --> 00:15:52,500
um Peter mentioned there that there are

368
00:15:48,779 --> 00:15:55,079
tools to to reconcile Wiki data to other

369
00:15:52,500 --> 00:15:56,760
data sets this is called mix and match

370
00:15:55,079 --> 00:15:58,440
so it just means that it does a it

371
00:15:56,760 --> 00:15:59,699
doesn't match on the name as you can see

372
00:15:58,440 --> 00:16:01,380
a lot of these aren't the the Western

373
00:15:59,699 --> 00:16:02,579
Australia Perth except for the second

374
00:16:01,380 --> 00:16:05,579
last one there

375
00:16:02,579 --> 00:16:09,000
and so that's a way that you can um that

376
00:16:05,579 --> 00:16:11,639
you can link wikidata to other data sets

377
00:16:09,000 --> 00:16:13,320
based on the name that you're doing that

378
00:16:11,639 --> 00:16:14,699
human touch and you're taking you're

379
00:16:13,320 --> 00:16:16,800
saying yes these are the same thing but

380
00:16:14,699 --> 00:16:18,360
this is this is not the same thing as I

381
00:16:16,800 --> 00:16:20,399
said that's an optional Gadget that I

382
00:16:18,360 --> 00:16:22,260
have installed so you generally won't

383
00:16:20,399 --> 00:16:24,180
see that

384
00:16:22,260 --> 00:16:25,880
but here's what you will say as Peter

385
00:16:24,180 --> 00:16:29,699
mentioned statements

386
00:16:25,880 --> 00:16:31,320
consisting of a property and a value and

387
00:16:29,699 --> 00:16:33,240
that property that value could be

388
00:16:31,320 --> 00:16:38,639
another Wiki data item that it's linking

389
00:16:33,240 --> 00:16:41,759
to or it could be a a string or a number

390
00:16:38,639 --> 00:16:43,019
such as a year or something like that so

391
00:16:41,759 --> 00:16:44,399
let's just go through it you can see you

392
00:16:43,019 --> 00:16:46,100
can have an image that images from

393
00:16:44,399 --> 00:16:48,779
Wikimedia Commons

394
00:16:46,100 --> 00:16:51,060
and can be used to to illustrate the

395
00:16:48,779 --> 00:16:52,440
item you can run queries when you I'll

396
00:16:51,060 --> 00:16:53,279
show you a bit about running queries

397
00:16:52,440 --> 00:16:55,440
later

398
00:16:53,279 --> 00:16:58,920
uh but you can actually sort of do

399
00:16:55,440 --> 00:17:01,680
queries on photos and uh and I'll tell

400
00:16:58,920 --> 00:17:04,279
you a bit more about structured data in

401
00:17:01,680 --> 00:17:04,279
images

402
00:17:04,980 --> 00:17:08,640
there's even a map of the coordinates of

403
00:17:07,500 --> 00:17:12,000
Perth

404
00:17:08,640 --> 00:17:13,140
um populations locator Maps the coat of

405
00:17:12,000 --> 00:17:16,079
arms

406
00:17:13,140 --> 00:17:18,059
so on so and so on and many many dialing

407
00:17:16,079 --> 00:17:20,819
codes and down the bottom they'll be

408
00:17:18,059 --> 00:17:23,640
identifiers so identifiers can be for

409
00:17:20,819 --> 00:17:25,280
people but they can also be for places

410
00:17:23,640 --> 00:17:28,380
organizations

411
00:17:25,280 --> 00:17:30,840
Concepts all sorts of things and it's

412
00:17:28,380 --> 00:17:34,679
just really useful to have these links

413
00:17:30,840 --> 00:17:36,539
to to other data sets

414
00:17:34,679 --> 00:17:37,679
if you just have all those data sets

415
00:17:36,539 --> 00:17:40,260
separately

416
00:17:37,679 --> 00:17:42,000
uh you know they'll have sort of they'll

417
00:17:40,260 --> 00:17:43,740
contain different data they might have

418
00:17:42,000 --> 00:17:46,980
different people with the same name

419
00:17:43,740 --> 00:17:48,600
being confused and this is this is a

420
00:17:46,980 --> 00:17:50,700
really good way wikidata is a really

421
00:17:48,600 --> 00:17:51,799
good way to to make sure that you know

422
00:17:50,700 --> 00:17:55,080
that that

423
00:17:51,799 --> 00:17:56,820
item refers to that person and there's

424
00:17:55,080 --> 00:17:58,740
no duplicates I mean of course there are

425
00:17:56,820 --> 00:18:00,900
some duplicates because sometimes an

426
00:17:58,740 --> 00:18:02,400
import is done and a duplicate is made

427
00:18:00,900 --> 00:18:04,260
but one that's one of the things that

428
00:18:02,400 --> 00:18:06,720
the volunteers are working on and sort

429
00:18:04,260 --> 00:18:10,220
of you know cleaning that up merging

430
00:18:06,720 --> 00:18:10,220
duplicated items

431
00:18:10,380 --> 00:18:16,620
so I've talked a bit about querying so

432
00:18:13,140 --> 00:18:18,600
this is the wikidata query service it

433
00:18:16,620 --> 00:18:22,760
uses a query language called the

434
00:18:18,600 --> 00:18:26,760
delightfully named Sparkle s-p-a-r-ql

435
00:18:22,760 --> 00:18:28,919
it's a bit like SQL or SQL but not quite

436
00:18:26,760 --> 00:18:30,720
so you'll see some familiar terms in

437
00:18:28,919 --> 00:18:34,799
there like select distinct

438
00:18:30,720 --> 00:18:36,720
order by and so on but then it is a

439
00:18:34,799 --> 00:18:37,799
quite it is a bit different and it's

440
00:18:36,720 --> 00:18:40,320
quite different because it's not looking

441
00:18:37,799 --> 00:18:42,299
at a relational database wikidat is kind

442
00:18:40,320 --> 00:18:43,080
of a rdf database so it's more like a

443
00:18:42,299 --> 00:18:45,299
graph

444
00:18:43,080 --> 00:18:47,760
graph system with nodes and it's all

445
00:18:45,299 --> 00:18:49,940
about linking one item to another item

446
00:18:47,760 --> 00:18:53,400
or a value

447
00:18:49,940 --> 00:18:55,200
so yeah it's I'm not going to explain or

448
00:18:53,400 --> 00:18:57,419
teach you how to do Sparkle which is a

449
00:18:55,200 --> 00:19:00,179
bit complicated if you do know SQL it's

450
00:18:57,419 --> 00:19:01,559
a bit it's a little bit easier what I

451
00:19:00,179 --> 00:19:04,020
would recommend if you're interested in

452
00:19:01,559 --> 00:19:05,880
in using it there's a query Builder you

453
00:19:04,020 --> 00:19:08,640
can see it at the top bar there

454
00:19:05,880 --> 00:19:10,799
so it's sort of a visual query Builder

455
00:19:08,640 --> 00:19:12,600
you can use a web form to to sort of

456
00:19:10,799 --> 00:19:14,460
build a query and it will actually

457
00:19:12,600 --> 00:19:16,440
translate that into the sparkle language

458
00:19:14,460 --> 00:19:19,440
so that you can and you can actually

459
00:19:16,440 --> 00:19:22,679
paste a permanent link it'll generate a

460
00:19:19,440 --> 00:19:24,720
short spots for Link Link shortcut URL

461
00:19:22,679 --> 00:19:27,559
and you can use that and go back to your

462
00:19:24,720 --> 00:19:27,559
query anytime

463
00:19:29,039 --> 00:19:33,600
it'll also translate it into Sparkle So

464
00:19:31,440 --> 00:19:35,640
if you want to you know tweak that query

465
00:19:33,600 --> 00:19:37,200
later you can do it what I'd also

466
00:19:35,640 --> 00:19:39,360
recommend you look at is these examples

467
00:19:37,200 --> 00:19:41,400
there's hundreds of examples of of

468
00:19:39,360 --> 00:19:43,200
queries that other people have written

469
00:19:41,400 --> 00:19:44,820
and if you can find one that does

470
00:19:43,200 --> 00:19:47,460
something similar to what you want to do

471
00:19:44,820 --> 00:19:50,900
it'll bring up the sparkle code for you

472
00:19:47,460 --> 00:19:54,720
and you can edit it and make changes so

473
00:19:50,900 --> 00:19:58,220
you might want to say uh

474
00:19:54,720 --> 00:19:58,220
so I had a look at one before

475
00:19:58,440 --> 00:20:03,480
a list of computer file formats

476
00:20:01,200 --> 00:20:05,340
so that's the the sparkle code for this

477
00:20:03,480 --> 00:20:07,620
query

478
00:20:05,340 --> 00:20:09,960
play

479
00:20:07,620 --> 00:20:11,419
around the query and you've got about

480
00:20:09,960 --> 00:20:13,860
thirteen thousand

481
00:20:11,419 --> 00:20:18,080
file extensions

482
00:20:13,860 --> 00:20:21,000
media types the on the left is the qid

483
00:20:18,080 --> 00:20:23,880
next column is the extension the my

484
00:20:21,000 --> 00:20:26,100
media type and then the the full full

485
00:20:23,880 --> 00:20:27,660
name of that

486
00:20:26,100 --> 00:20:29,220
um and it's fairly quick that was like

487
00:20:27,660 --> 00:20:32,280
about five seconds

488
00:20:29,220 --> 00:20:35,100
um to bring up 13 000 results there are

489
00:20:32,280 --> 00:20:36,900
some um issues with the the query engine

490
00:20:35,100 --> 00:20:38,580
it is it can be a bit slow and it can

491
00:20:36,900 --> 00:20:40,140
time out with very very complicated

492
00:20:38,580 --> 00:20:42,179
queries in as you can imagine with a

493
00:20:40,140 --> 00:20:45,480
data set of this size or a database of

494
00:20:42,179 --> 00:20:46,980
this size that can be quite slow if you

495
00:20:45,480 --> 00:20:47,900
do want to do something that's really

496
00:20:46,980 --> 00:20:51,120
really really

497
00:20:47,900 --> 00:20:53,940
uh complicated and requires a lot of

498
00:20:51,120 --> 00:20:56,580
data you can actually download dumps of

499
00:20:53,940 --> 00:20:59,160
the whole wikidata Corpus and you can

500
00:20:56,580 --> 00:21:01,640
you can read it in and process that how

501
00:20:59,160 --> 00:21:01,640
you want it

502
00:21:03,299 --> 00:21:07,020
and there's just some exciting projects

503
00:21:05,760 --> 00:21:09,179
that are

504
00:21:07,020 --> 00:21:11,100
um that are using wikidata obviously

505
00:21:09,179 --> 00:21:12,480
there's all the wikipedias the many

506
00:21:11,100 --> 00:21:15,660
language editions of Wikipedia

507
00:21:12,480 --> 00:21:17,460
structured data on Commons so Peter

508
00:21:15,660 --> 00:21:20,400
showed you about Commons as a central

509
00:21:17,460 --> 00:21:22,500
image Library uh contains millions and

510
00:21:20,400 --> 00:21:23,240
millions of photographs diagrams and so

511
00:21:22,500 --> 00:21:26,820
on

512
00:21:23,240 --> 00:21:28,919
and a new project that has been put in

513
00:21:26,820 --> 00:21:31,500
using wikidata is structured data so

514
00:21:28,919 --> 00:21:33,539
that you can actually use these triples

515
00:21:31,500 --> 00:21:37,220
that you'd use in wikidata of what

516
00:21:33,539 --> 00:21:39,840
something depicts or where it was taken

517
00:21:37,220 --> 00:21:41,760
where a photo was taken for example who

518
00:21:39,840 --> 00:21:44,100
who took the photo or painted the

519
00:21:41,760 --> 00:21:44,820
painting and so on you can you can build

520
00:21:44,100 --> 00:21:47,600
up

521
00:21:44,820 --> 00:21:50,039
structured data about an image

522
00:21:47,600 --> 00:21:52,980
in Wikimedia Commons and that's using

523
00:21:50,039 --> 00:21:55,620
the the wiki data or the wikibase engine

524
00:21:52,980 --> 00:21:57,240
that's really useful for all sorts of

525
00:21:55,620 --> 00:21:59,940
things obviously it makes searching for

526
00:21:57,240 --> 00:22:02,640
images easier than just searching for

527
00:21:59,940 --> 00:22:05,460
names or descriptions you can actually

528
00:22:02,640 --> 00:22:08,220
do structured and complex queries for

529
00:22:05,460 --> 00:22:11,400
images it could also be used for for

530
00:22:08,220 --> 00:22:13,980
training image models in machine

531
00:22:11,400 --> 00:22:16,260
learning so you can you can use that

532
00:22:13,980 --> 00:22:19,140
that structured data that's sitting

533
00:22:16,260 --> 00:22:21,720
behind all those images there's a new

534
00:22:19,140 --> 00:22:24,600
project that's not complete yet it's

535
00:22:21,720 --> 00:22:26,100
still a work in progress called abstract

536
00:22:24,600 --> 00:22:27,960
Wikipedia

537
00:22:26,100 --> 00:22:28,740
that's using

538
00:22:27,960 --> 00:22:30,179
um

539
00:22:28,740 --> 00:22:33,299
so I mentioned that there's the

540
00:22:30,179 --> 00:22:35,940
multilingual aspect of wikidata where it

541
00:22:33,299 --> 00:22:38,840
you have all those languages for

542
00:22:35,940 --> 00:22:38,840
for everything

543
00:22:42,419 --> 00:22:46,260
so languages for the labels and

544
00:22:44,340 --> 00:22:48,360
descriptions but there's also a new type

545
00:22:46,260 --> 00:22:50,760
you can see here lexographical data

546
00:22:48,360 --> 00:22:51,960
create a new lexime so there's a whole

547
00:22:50,760 --> 00:22:54,000
section of wikidata which is about

548
00:22:51,960 --> 00:22:57,000
leximes which is about creating tensors

549
00:22:54,000 --> 00:23:00,000
and sensors of terms and and words in in

550
00:22:57,000 --> 00:23:01,559
as many languages as possible and where

551
00:23:00,000 --> 00:23:03,539
that's going to become useful is that

552
00:23:01,559 --> 00:23:05,159
the Wikimedia Foundation is working on a

553
00:23:03,539 --> 00:23:09,140
project called abstract Wikipedia and

554
00:23:05,159 --> 00:23:11,400
Wiki functions and that is uh will allow

555
00:23:09,140 --> 00:23:13,799
wikipedias and Wikipedia articles to be

556
00:23:11,400 --> 00:23:17,159
generated using wikidata and using the

557
00:23:13,799 --> 00:23:20,400
leximes and using Wiki functions to

558
00:23:17,159 --> 00:23:23,580
generate articles sort of Wikipedia

559
00:23:20,400 --> 00:23:25,860
style articles in in any language even

560
00:23:23,580 --> 00:23:29,419
in small languages with not many

561
00:23:25,860 --> 00:23:29,419
articles on on their Wikipedia

562
00:23:30,659 --> 00:23:37,200
there's also Wiki site Wiki site is a

563
00:23:33,780 --> 00:23:39,960
project Creator bibliographic database

564
00:23:37,200 --> 00:23:42,480
and actually if you click on random item

565
00:23:39,960 --> 00:23:45,059
in wikidata they'll deserve that you'll

566
00:23:42,480 --> 00:23:49,799
you'll come across pretty quickly a um

567
00:23:45,059 --> 00:23:51,600
a scientific article or academic Journal

568
00:23:49,799 --> 00:23:53,640
article

569
00:23:51,600 --> 00:23:55,440
um because uh there's a lot of work done

570
00:23:53,640 --> 00:23:59,100
on this and it's quite a that's a huge

571
00:23:55,440 --> 00:24:03,240
task to to bring in every uh academic

572
00:23:59,100 --> 00:24:05,820
scientific scholarly article to link

573
00:24:03,240 --> 00:24:09,179
those articles to the authors the

574
00:24:05,820 --> 00:24:12,120
scientists or the the um the academics

575
00:24:09,179 --> 00:24:14,220
who wrote them the University or the

576
00:24:12,120 --> 00:24:16,679
organization those those people work for

577
00:24:14,220 --> 00:24:19,140
the authors work for and so on

578
00:24:16,679 --> 00:24:21,679
um so about half of wikidata is probably

579
00:24:19,140 --> 00:24:25,039
uh these sort of Articles and uh

580
00:24:21,679 --> 00:24:27,960
academic and bibliographic information

581
00:24:25,039 --> 00:24:29,640
that allows a really amazing this tool

582
00:24:27,960 --> 00:24:31,740
called scolia which allows you to to

583
00:24:29,640 --> 00:24:33,480
produce a to you know you can put an

584
00:24:31,740 --> 00:24:35,340
academic or a scientist or someone who

585
00:24:33,480 --> 00:24:39,000
writes articles in and it will produce

586
00:24:35,340 --> 00:24:40,440
dozens of visualizations of uh of their

587
00:24:39,000 --> 00:24:42,419
work and what they've they've written

588
00:24:40,440 --> 00:24:44,580
about

589
00:24:42,419 --> 00:24:46,620
speaking of visualizations in the query

590
00:24:44,580 --> 00:24:48,659
service so I've bought a to run that

591
00:24:46,620 --> 00:24:52,919
query here and there's it's brought up a

592
00:24:48,659 --> 00:24:55,799
a tabular list of what I asked it for

593
00:24:52,919 --> 00:24:57,600
but built in there's also a huge number

594
00:24:55,799 --> 00:25:00,179
of visualizations so it's got table

595
00:24:57,600 --> 00:25:01,860
there by by default but you can also do

596
00:25:00,179 --> 00:25:03,539
a grid of images if you're searching

597
00:25:01,860 --> 00:25:06,020
doing a search for particular types of

598
00:25:03,539 --> 00:25:08,880
images or images to depict a particular

599
00:25:06,020 --> 00:25:12,419
thing like you might do flags with a

600
00:25:08,880 --> 00:25:14,340
lion or flags with the the um the Union

601
00:25:12,419 --> 00:25:17,039
Jack on it or something like that and it

602
00:25:14,340 --> 00:25:18,840
will bring all those up but the whole

603
00:25:17,039 --> 00:25:21,960
you know line charts bar charts scatter

604
00:25:18,840 --> 00:25:23,820
charts bubble charts Maps so Geographic

605
00:25:21,960 --> 00:25:25,559
Maps if the items that you're coming up

606
00:25:23,820 --> 00:25:26,760
in your query have Geographic

607
00:25:25,559 --> 00:25:30,000
coordinates

608
00:25:26,760 --> 00:25:31,559
or even boundary data that's loaded into

609
00:25:30,000 --> 00:25:33,659
Wikimedia Commons

610
00:25:31,559 --> 00:25:35,340
you can you can actually bring up maps

611
00:25:33,659 --> 00:25:37,260
and display those on a on a map of the

612
00:25:35,340 --> 00:25:39,720
world using openstreetmap

613
00:25:37,260 --> 00:25:42,000
an openstreetmap links very well to to

614
00:25:39,720 --> 00:25:46,500
wikidata wikidata links to openstreetmap

615
00:25:42,000 --> 00:25:50,340
relations and also and nodes lines and

616
00:25:46,500 --> 00:25:53,760
so on but also openstreetmap very widely

617
00:25:50,340 --> 00:25:55,620
uses Wiki data for for many purposes

618
00:25:53,760 --> 00:25:58,440
um including you know just for for

619
00:25:55,620 --> 00:26:00,779
showing logos of companies or

620
00:25:58,440 --> 00:26:03,140
um and for linking to the the Wikipedia

621
00:26:00,779 --> 00:26:03,140
articles

622
00:26:09,600 --> 00:26:14,220
me

623
00:26:10,919 --> 00:26:16,799
and so you can download the the results

624
00:26:14,220 --> 00:26:18,620
of your queries as some

625
00:26:16,799 --> 00:26:23,220
Json

626
00:26:18,620 --> 00:26:24,480
tsv tabs operated values CSV or an HTML

627
00:26:23,220 --> 00:26:27,720
table

628
00:26:24,480 --> 00:26:31,260
and best of all there's a code

629
00:26:27,720 --> 00:26:31,860
option so you have all these options to

630
00:26:31,260 --> 00:26:37,080
um

631
00:26:31,860 --> 00:26:41,900
generate code in HTML PHP JavaScript

632
00:26:37,080 --> 00:26:45,539
Java Perl python Ruby R Matlab

633
00:26:41,900 --> 00:26:47,039
listeria is a um is a particular module

634
00:26:45,539 --> 00:26:48,179
for Wikipedia projects to generate

635
00:26:47,039 --> 00:26:51,059
tables

636
00:26:48,179 --> 00:26:53,820
and and map frames so

637
00:26:51,059 --> 00:26:57,080
um yeah that's uh I'll show you a

638
00:26:53,820 --> 00:26:57,080
example and say python

639
00:27:00,000 --> 00:27:04,440
so you might have to install

640
00:27:01,980 --> 00:27:06,020
um you know some some libraries and

641
00:27:04,440 --> 00:27:09,840
plugins to to

642
00:27:06,020 --> 00:27:11,760
communicate with the the wiki data API

643
00:27:09,840 --> 00:27:13,440
but yeah once you've done that you can

644
00:27:11,760 --> 00:27:16,440
you can run your query in Sparkle which

645
00:27:13,440 --> 00:27:18,059
you said you can generate it and uh and

646
00:27:16,440 --> 00:27:19,980
um and then we'll get this you can

647
00:27:18,059 --> 00:27:24,500
download put this code into your

648
00:27:19,980 --> 00:27:24,500
software and load that as a data frame

649
00:27:30,059 --> 00:27:35,520
and as I said you can generate a

650
00:27:32,900 --> 00:27:36,860
permanent link to your query so if you

651
00:27:35,520 --> 00:27:40,020
want to

652
00:27:36,860 --> 00:27:41,520
post it you don't it can be on Wikimedia

653
00:27:40,020 --> 00:27:43,020
but you can post it on a you know if you

654
00:27:41,520 --> 00:27:45,059
want to put it on a blog or email it to

655
00:27:43,020 --> 00:27:46,039
someone and just say here's a query I've

656
00:27:45,059 --> 00:27:49,980
done

657
00:27:46,039 --> 00:27:52,679
for this topic

658
00:27:49,980 --> 00:27:55,320
um yeah so

659
00:27:52,679 --> 00:27:59,000
that's

660
00:27:55,320 --> 00:27:59,000
the demo

661
00:28:03,900 --> 00:28:10,200
the types of tools a heap number tools

662
00:28:07,559 --> 00:28:13,860
so the tools use the wiki data and

663
00:28:10,200 --> 00:28:16,380
wikibase API if you want to build your

664
00:28:13,860 --> 00:28:19,020
own tools like I said you can become

665
00:28:16,380 --> 00:28:21,299
okay with that API but there's dozens

666
00:28:19,020 --> 00:28:24,000
and dozens of tools I've been using

667
00:28:21,299 --> 00:28:26,220
wikidata for years and every even every

668
00:28:24,000 --> 00:28:28,380
time I meet meet someone who is also

669
00:28:26,220 --> 00:28:30,000
interested in this they they find that

670
00:28:28,380 --> 00:28:31,260
they haven't uh

671
00:28:30,000 --> 00:28:33,720
um you know they tell me about tools

672
00:28:31,260 --> 00:28:37,020
that I haven't heard of and

673
00:28:33,720 --> 00:28:38,880
yeah the wikidata is amazing for doing

674
00:28:37,020 --> 00:28:40,440
research on Wikipedia like I said

675
00:28:38,880 --> 00:28:43,200
because it kind of forms the backbone of

676
00:28:40,440 --> 00:28:46,020
Wikipedia a lot of researchers and

677
00:28:43,200 --> 00:28:49,500
academics doing work about how Wikipedia

678
00:28:46,020 --> 00:28:52,080
works can use wikidata to do queries of

679
00:28:49,500 --> 00:28:53,880
of things like um you know how many

680
00:28:52,080 --> 00:28:56,520
edits an article has got or when it was

681
00:28:53,880 --> 00:29:00,179
started when it was created or when it

682
00:28:56,520 --> 00:29:02,220
when it got to the most edits

683
00:29:00,179 --> 00:29:04,620
the whole Community there that Peter

684
00:29:02,220 --> 00:29:06,120
mentioned the the Wikimedia Community is

685
00:29:04,620 --> 00:29:07,140
always willing to help you and if you do

686
00:29:06,120 --> 00:29:08,820
have a

687
00:29:07,140 --> 00:29:11,220
not sure how to write a query and you

688
00:29:08,820 --> 00:29:14,240
can't find an example in the those

689
00:29:11,220 --> 00:29:16,500
examples or

690
00:29:14,240 --> 00:29:19,140
it's too complicated for the query

691
00:29:16,500 --> 00:29:21,480
visual query Builder you can absolutely

692
00:29:19,140 --> 00:29:23,880
ask click on that help

693
00:29:21,480 --> 00:29:26,700
and it will take you to a page where you

694
00:29:23,880 --> 00:29:29,700
can you can ask for someone to develop a

695
00:29:26,700 --> 00:29:32,840
query for you and they'll usually get

696
00:29:29,700 --> 00:29:32,840
back to you within a day or two

697
00:29:36,299 --> 00:29:43,460
in the instance instances and subclasses

698
00:29:39,559 --> 00:29:43,460
on a on an article

699
00:29:43,620 --> 00:29:46,679
um

700
00:29:44,279 --> 00:29:49,320
what makes this really powerful is it's

701
00:29:46,679 --> 00:29:51,539
uh the subclasses could be can be

702
00:29:49,320 --> 00:29:52,740
recursive and that means that you can

703
00:29:51,539 --> 00:29:53,460
you can actually

704
00:29:52,740 --> 00:29:56,640
um

705
00:29:53,460 --> 00:29:59,100
do a query that uh you know sort of goes

706
00:29:56,640 --> 00:30:00,960
as more as detailed or as or as far back

707
00:29:59,100 --> 00:30:03,000
as you like and it can sort of actually

708
00:30:00,960 --> 00:30:04,860
recurse into that so Peter showed you

709
00:30:03,000 --> 00:30:06,840
the big things and there are subclass of

710
00:30:04,860 --> 00:30:08,940
sculpture or a subclass of tourist

711
00:30:06,840 --> 00:30:10,380
attraction you could sort of do a query

712
00:30:08,940 --> 00:30:12,120
for tourist attractions and it would

713
00:30:10,380 --> 00:30:13,919
find things that are an instance of

714
00:30:12,120 --> 00:30:15,779
something that is a type of tourist

715
00:30:13,919 --> 00:30:17,940
attraction

716
00:30:15,779 --> 00:30:21,419
um it just means you can use it as a to

717
00:30:17,940 --> 00:30:23,940
build up ontologies and vocabularies

718
00:30:21,419 --> 00:30:27,360
um uh so you know and and that can be

719
00:30:23,940 --> 00:30:29,340
that can be searched and scanned

720
00:30:27,360 --> 00:30:31,880
um in the in the graph that it's uh

721
00:30:29,340 --> 00:30:31,880
stored in

722
00:30:33,240 --> 00:30:38,460
okay so um that's all to show you today

723
00:30:37,679 --> 00:30:41,720
um

724
00:30:38,460 --> 00:30:41,720
is there any questions

725
00:30:42,179 --> 00:30:44,659
anything else

726
00:30:51,480 --> 00:30:53,480
um

727
00:31:02,640 --> 00:31:07,440
song

728
00:31:04,860 --> 00:31:09,659
hello uh hello

729
00:31:07,440 --> 00:31:13,320
um thank you that was very interesting

730
00:31:09,659 --> 00:31:15,059
um you mentioned Imports and an API and

731
00:31:13,320 --> 00:31:18,240
I was just wondering about some

732
00:31:15,059 --> 00:31:21,480
information about if I assume people are

733
00:31:18,240 --> 00:31:25,080
from that automatically importing data

734
00:31:21,480 --> 00:31:27,179
into this system and I just wanted uh

735
00:31:25,080 --> 00:31:32,340
kind of how that happened technically

736
00:31:27,179 --> 00:31:33,899
and also socially as well yeah yeah it's

737
00:31:32,340 --> 00:31:35,100
a good good question

738
00:31:33,899 --> 00:31:38,039
um so

739
00:31:35,100 --> 00:31:39,240
there are ways to I didn't show it to

740
00:31:38,039 --> 00:31:41,279
you but there's a there's a system

741
00:31:39,240 --> 00:31:43,620
called quick statements where where you

742
00:31:41,279 --> 00:31:46,799
can generate a sort of table or sort of

743
00:31:43,620 --> 00:31:49,260
tab delimited table of these triples

744
00:31:46,799 --> 00:31:51,179
that the wikidata is stored in so you

745
00:31:49,260 --> 00:31:52,980
you have one queue number and then the

746
00:31:51,179 --> 00:31:54,840
property and then another queue number

747
00:31:52,980 --> 00:31:57,600
and so on so it just runs those and

748
00:31:54,840 --> 00:31:59,100
that's a way to sort of do Imports but

749
00:31:57,600 --> 00:32:01,020
yeah you're right socially there there

750
00:31:59,100 --> 00:32:02,640
is an issue if you're just grabbing a

751
00:32:01,020 --> 00:32:06,059
data set you know

752
00:32:02,640 --> 00:32:07,559
importing a huge data set and as I said

753
00:32:06,059 --> 00:32:09,960
it's very important that you have these

754
00:32:07,559 --> 00:32:11,880
things as you know that there's only

755
00:32:09,960 --> 00:32:13,500
sort of one instance of a particular

756
00:32:11,880 --> 00:32:15,419
person or a particular company or a

757
00:32:13,500 --> 00:32:16,380
particular town or you know Village or

758
00:32:15,419 --> 00:32:19,740
something

759
00:32:16,380 --> 00:32:21,720
um in the the system so uh yeah there

760
00:32:19,740 --> 00:32:23,399
are tools to

761
00:32:21,720 --> 00:32:24,299
um so there's a tool called mix and

762
00:32:23,399 --> 00:32:24,960
match

763
00:32:24,299 --> 00:32:27,360
um

764
00:32:24,960 --> 00:32:29,460
which is um I can show you that's on one

765
00:32:27,360 --> 00:32:32,279
of those slides as well

766
00:32:29,460 --> 00:32:34,320
so mix and match uses these uh sort of

767
00:32:32,279 --> 00:32:36,539
has a huge number of thousands of

768
00:32:34,320 --> 00:32:37,520
catalogs so these are essentially data

769
00:32:36,539 --> 00:32:40,260
sets

770
00:32:37,520 --> 00:32:43,940
the system uh so you know you've got a

771
00:32:40,260 --> 00:32:43,940
lot of ones about video games

772
00:32:44,460 --> 00:32:50,039
and uh what it does basically is it

773
00:32:47,100 --> 00:32:54,539
loads the data set in tries to match it

774
00:32:50,039 --> 00:32:56,279
to a wikidata item and uh and then if

775
00:32:54,539 --> 00:32:57,840
the name matches and it's pretty sure

776
00:32:56,279 --> 00:32:59,940
it's the same thing it'll preliminarily

777
00:32:57,840 --> 00:33:01,500
match it but what it wants is a human to

778
00:32:59,940 --> 00:33:03,539
come in you know with someone one of the

779
00:33:01,500 --> 00:33:05,299
volunteers to come in and look at that

780
00:33:03,539 --> 00:33:07,200
and go no that's definitely not the same

781
00:33:05,299 --> 00:33:09,480
person in

782
00:33:07,200 --> 00:33:11,940
wikidata in the data set

783
00:33:09,480 --> 00:33:14,279
um so or you know yes it definitely is

784
00:33:11,940 --> 00:33:15,840
so there's a lot of these there's as I

785
00:33:14,279 --> 00:33:18,179
said there's thousands of these catalogs

786
00:33:15,840 --> 00:33:21,059
for all sorts of data sets from all

787
00:33:18,179 --> 00:33:23,100
sorts of from all over the web

788
00:33:21,059 --> 00:33:25,320
um and uh you know the various levels of

789
00:33:23,100 --> 00:33:27,299
matching so these video games yeah I'll

790
00:33:25,320 --> 00:33:29,159
show you a quick example let's look at

791
00:33:27,299 --> 00:33:32,460
some unmatched ones

792
00:33:29,159 --> 00:33:34,799
90s arcade racer

793
00:33:32,460 --> 00:33:37,860
uh and so so yeah it'll check check

794
00:33:34,799 --> 00:33:40,260
Wikipedia it'll check um Wiki data it'll

795
00:33:37,860 --> 00:33:42,179
um and it'll check other other catalogs

796
00:33:40,260 --> 00:33:44,640
and uh if I go oh well I'm pretty sure

797
00:33:42,179 --> 00:33:47,039
this this item isn't already in Wiki

798
00:33:44,640 --> 00:33:49,559
data I can create a new item and it will

799
00:33:47,039 --> 00:33:51,539
automatically match it to this catalog

800
00:33:49,559 --> 00:33:53,519
so yeah you're right it's very important

801
00:33:51,539 --> 00:33:54,840
that not to just dump a whole data set

802
00:33:53,519 --> 00:33:57,840
in there

803
00:33:54,840 --> 00:34:00,260
um it's good to use tools like this to

804
00:33:57,840 --> 00:34:04,140
to sort of reconcile what is already in

805
00:34:00,260 --> 00:34:06,000
wikidata and Wikipedia with um the the

806
00:34:04,140 --> 00:34:08,779
data set that you're uploading so yeah

807
00:34:06,000 --> 00:34:08,779
excellent questions

808
00:34:12,179 --> 00:34:19,919
used is open refine as well so there's a

809
00:34:16,500 --> 00:34:22,560
plug-in like built into that so it

810
00:34:19,919 --> 00:34:24,839
allows you to query Wiki data directly

811
00:34:22,560 --> 00:34:26,879
and do that reconciliation as well and

812
00:34:24,839 --> 00:34:29,099
it'll generate those quick statements

813
00:34:26,879 --> 00:34:31,080
for you to then then upload as well so

814
00:34:29,099 --> 00:34:36,200
it's a very common way what how people

815
00:34:31,080 --> 00:34:36,200
can look at data and match it up as well

816
00:34:43,440 --> 00:34:48,240
so maybe a sort of follow-on question

817
00:34:45,359 --> 00:34:50,700
from that the there's a lot of data in

818
00:34:48,240 --> 00:34:52,200
Wikipedia itself that isn't in Wiki data

819
00:34:50,700 --> 00:34:55,560
so you mentioned Perth and if you look

820
00:34:52,200 --> 00:34:57,720
at Wikipedia itself if you go to the

821
00:34:55,560 --> 00:34:59,880
language drop down it's got perf as an

822
00:34:57,720 --> 00:35:01,980
article in 100 other languages which

823
00:34:59,880 --> 00:35:04,440
isn't in Wiki data

824
00:35:01,980 --> 00:35:06,420
um so maybe there is an API to copy that

825
00:35:04,440 --> 00:35:09,180
across but to me it seems like that's

826
00:35:06,420 --> 00:35:10,980
duplicating data as well and Wikipedia

827
00:35:09,180 --> 00:35:12,839
is kind of a related projects that have

828
00:35:10,980 --> 00:35:14,839
have been like considerations in

829
00:35:12,839 --> 00:35:17,460
actually just store the data in

830
00:35:14,839 --> 00:35:18,359
Wikipedia and then extract it to Wiki

831
00:35:17,460 --> 00:35:20,520
data

832
00:35:18,359 --> 00:35:22,440
yeah um

833
00:35:20,520 --> 00:35:24,720
that's true there's not um I mean not

834
00:35:22,440 --> 00:35:26,820
everything everything in Wikipedia is in

835
00:35:24,720 --> 00:35:28,740
wikidata the languages like where

836
00:35:26,820 --> 00:35:30,599
there's an article in one language in

837
00:35:28,740 --> 00:35:33,540
another that's that's how it is managed

838
00:35:30,599 --> 00:35:36,780
on Wikipedia is using wikidata so

839
00:35:33,540 --> 00:35:39,859
um I could bring back Perth

840
00:35:36,780 --> 00:35:39,859
so all the um

841
00:35:41,760 --> 00:35:46,280
right down the bottom I should have

842
00:35:43,200 --> 00:35:46,280
chosen a shorter one

843
00:35:47,400 --> 00:35:51,119
so these are all the the language

844
00:35:48,980 --> 00:35:54,500
editions of Wikipedia with an article

845
00:35:51,119 --> 00:35:54,500
about this this item

846
00:35:55,380 --> 00:36:00,420
but yeah not everything uh in all of

847
00:35:58,500 --> 00:36:01,800
those languages or in all bits of data

848
00:36:00,420 --> 00:36:03,240
even sort of relevant bits of data are

849
00:36:01,800 --> 00:36:05,280
necessarily in those languages and yeah

850
00:36:03,240 --> 00:36:07,079
that's that's you know something that

851
00:36:05,280 --> 00:36:10,079
can be built up um as I mentioned there

852
00:36:07,079 --> 00:36:12,420
is a Wikimedia API so it's not just

853
00:36:10,079 --> 00:36:15,540
using wikidata but there's a tool called

854
00:36:12,420 --> 00:36:18,720
pet scan and that actually can use

855
00:36:15,540 --> 00:36:20,960
um all sorts of aspects of uh and

856
00:36:18,720 --> 00:36:23,579
metadata about Wikipedia articles

857
00:36:20,960 --> 00:36:25,740
Wikimedia Commons and Wiki data will all

858
00:36:23,579 --> 00:36:27,180
combined so it's very powerful tool it's

859
00:36:25,740 --> 00:36:28,920
not just doing a query but you can

860
00:36:27,180 --> 00:36:31,560
include queries from wikidata and

861
00:36:28,920 --> 00:36:33,540
combine them with with information so as

862
00:36:31,560 --> 00:36:36,000
she said if you're doing you know if you

863
00:36:33,540 --> 00:36:37,920
do want information about the Wikipedia

864
00:36:36,000 --> 00:36:39,839
article when it was created and you know

865
00:36:37,920 --> 00:36:42,000
how many page views it got and so on you

866
00:36:39,839 --> 00:36:44,339
can use these tools to sort of

867
00:36:42,000 --> 00:36:47,420
um to sort of combine all those

868
00:36:44,339 --> 00:36:47,420
resources and tools together

869
00:37:00,359 --> 00:37:04,140
um this is more of a comment but this

870
00:37:02,460 --> 00:37:06,440
conference doesn't have a Wiki data

871
00:37:04,140 --> 00:37:06,440
entry

872
00:37:06,720 --> 00:37:11,880
what if people want to go and create one

873
00:37:09,780 --> 00:37:13,500
it'd probably be useful

874
00:37:11,880 --> 00:37:15,119
excellent point and I did I did you're

875
00:37:13,500 --> 00:37:16,619
right I did find that five minutes ago

876
00:37:15,119 --> 00:37:19,560
uh we got about to you know 10 minutes

877
00:37:16,619 --> 00:37:21,359
before I was just going to going to edit

878
00:37:19,560 --> 00:37:22,440
and then so it wasn't on it so yes we

879
00:37:21,359 --> 00:37:25,820
can definitely do something about that

880
00:37:22,440 --> 00:37:25,820
thanks for pointing it out

881
00:37:27,660 --> 00:37:31,760
yeah anyone can add that yeah

882
00:37:32,280 --> 00:37:36,240
I can't see any questions so I'll pop

883
00:37:35,099 --> 00:37:37,920
one in

884
00:37:36,240 --> 00:37:41,099
um one of the things that I sometimes

885
00:37:37,920 --> 00:37:43,200
consult on Wikipedia is the edit history

886
00:37:41,099 --> 00:37:44,520
and discussion page because there are

887
00:37:43,200 --> 00:37:46,079
some things that not settled and

888
00:37:44,520 --> 00:37:48,000
obviously reading them

889
00:37:46,079 --> 00:37:50,160
reveals what's silver and what's not

890
00:37:48,000 --> 00:37:52,440
like this is a repository a facts I

891
00:37:50,160 --> 00:37:54,660
presume the same sort of disputes arise

892
00:37:52,440 --> 00:37:57,060
is is it have a similar mechanism you

893
00:37:54,660 --> 00:37:58,619
can consult over what's in dispute and

894
00:37:57,060 --> 00:38:00,060
what's certain yeah it's very similar

895
00:37:58,619 --> 00:38:02,040
it's almost you know exactly the same

896
00:38:00,060 --> 00:38:05,280
here so which item has a talk page but I

897
00:38:02,040 --> 00:38:07,980
guess they're not as widely used as

898
00:38:05,280 --> 00:38:09,000
was on Wikipedia and meant that's why

899
00:38:07,980 --> 00:38:10,619
maybe that's a good thing they probably

900
00:38:09,000 --> 00:38:12,720
don't the the discussions don't get as

901
00:38:10,619 --> 00:38:13,619
heated as they may on Wikipedia I think

902
00:38:12,720 --> 00:38:15,540
that's one thing I do like about

903
00:38:13,619 --> 00:38:17,400
wikidata it's a lot less uh you know

904
00:38:15,540 --> 00:38:20,520
there's a very collaborative Community

905
00:38:17,400 --> 00:38:24,119
but it's uh you know not not as uh I

906
00:38:20,520 --> 00:38:26,220
guess um prone to to edit Wars and

907
00:38:24,119 --> 00:38:28,619
arguments uh you know it is Data it's

908
00:38:26,220 --> 00:38:30,599
supposed to be factual so

909
00:38:28,619 --> 00:38:32,579
um and but just like Wikipedia every

910
00:38:30,599 --> 00:38:34,619
there's a history edit history and you

911
00:38:32,579 --> 00:38:36,599
can put you know edit comments in and so

912
00:38:34,619 --> 00:38:39,119
on so it's very similar in that regard

913
00:38:36,599 --> 00:38:41,460
everything's logged uh if you did say

914
00:38:39,119 --> 00:38:44,220
import something and and it was wrong

915
00:38:41,460 --> 00:38:47,400
like I once imported all these Heritage

916
00:38:44,220 --> 00:38:49,859
items in Perth in Fremantle and and uh I

917
00:38:47,400 --> 00:38:51,720
got the coordinates I rounded the off

918
00:38:49,859 --> 00:38:53,579
the coordinates too much and so you know

919
00:38:51,720 --> 00:38:55,920
but it's very easy to if it's easy to

920
00:38:53,579 --> 00:38:59,280
put it in it's also easy to

921
00:38:55,920 --> 00:39:00,920
um remove it or remove sort of bits of

922
00:38:59,280 --> 00:39:03,119
data like that too so

923
00:39:00,920 --> 00:39:04,619
and yeah as I said it's all it's all

924
00:39:03,119 --> 00:39:06,180
logged and you can roll things back and

925
00:39:04,619 --> 00:39:08,280
revert them to to where they were if

926
00:39:06,180 --> 00:39:10,500
someone does do do any vandalism

927
00:39:08,280 --> 00:39:12,720
vandalism yeah

928
00:39:10,500 --> 00:39:15,240
um the other part of that is the whole

929
00:39:12,720 --> 00:39:17,400
entire ontology and information model is

930
00:39:15,240 --> 00:39:19,800
also Community built as well so there's

931
00:39:17,400 --> 00:39:22,260
a lot of discussion around what are the

932
00:39:19,800 --> 00:39:24,300
classes what are the subclasses um how

933
00:39:22,260 --> 00:39:26,940
does that actually work so you know it's

934
00:39:24,300 --> 00:39:28,800
it's not kind of designed perfectly from

935
00:39:26,940 --> 00:39:30,480
from the top down so you know there may

936
00:39:28,800 --> 00:39:32,220
be issues but they're they're worked out

937
00:39:30,480 --> 00:39:34,380
in that same way they're discussed and

938
00:39:32,220 --> 00:39:36,540
talked about and agreed upon so you end

939
00:39:34,380 --> 00:39:38,520
up with something that ultimately should

940
00:39:36,540 --> 00:39:40,619
be should be really useful for the

941
00:39:38,520 --> 00:39:43,500
community so anyone could add an item

942
00:39:40,619 --> 00:39:46,140
like an object or a thing or a concept

943
00:39:43,500 --> 00:39:47,640
but for the properties those are the you

944
00:39:46,140 --> 00:39:48,540
know the things that the middle of the

945
00:39:47,640 --> 00:39:50,099
triple

946
00:39:48,540 --> 00:39:51,839
um they're they're sort of I guess

947
00:39:50,099 --> 00:39:54,060
proposed to the community and the

948
00:39:51,839 --> 00:39:55,740
community discusses whether they're is

949
00:39:54,060 --> 00:39:58,200
it needed is it is there another one

950
00:39:55,740 --> 00:40:00,420
that can be used or in you know yes this

951
00:39:58,200 --> 00:40:01,980
one sounds good we can bring it in so

952
00:40:00,420 --> 00:40:04,859
that's uh yeah that's one of the many

953
00:40:01,980 --> 00:40:07,560
things the community sort of does so

954
00:40:04,859 --> 00:40:09,660
there's a balance between anyone can

955
00:40:07,560 --> 00:40:13,740
edit and can doing anything but some

956
00:40:09,660 --> 00:40:16,260
things are I do have discussions and uh

957
00:40:13,740 --> 00:40:18,740
and the community deciding if that's

958
00:40:16,260 --> 00:40:18,740
appropriate

959
00:40:20,099 --> 00:40:24,260
people you'll get another boring

960
00:40:21,420 --> 00:40:24,260
question from me

961
00:40:24,720 --> 00:40:27,480
it's a smoking gift I might actually ask

962
00:40:26,640 --> 00:40:28,980
one

963
00:40:27,480 --> 00:40:32,760
um speaking of community and consensus

964
00:40:28,980 --> 00:40:35,040
this is a tool comprised of many many

965
00:40:32,760 --> 00:40:36,500
many sophisticated tools could you give

966
00:40:35,040 --> 00:40:39,660
us an overview of

967
00:40:36,500 --> 00:40:43,020
how the community reached consensus to

968
00:40:39,660 --> 00:40:45,619
say create the qid

969
00:40:43,020 --> 00:40:48,720
a lot of effort I'm sure went into that

970
00:40:45,619 --> 00:40:51,240
well that's interesting the qid is um

971
00:40:48,720 --> 00:40:53,280
like um people saying you know why is it

972
00:40:51,240 --> 00:40:54,780
queue who knows it was actually

973
00:40:53,280 --> 00:40:57,720
um

974
00:40:54,780 --> 00:40:59,640
uh a the developer who was who kind of

975
00:40:57,720 --> 00:41:01,380
built the the wikibase software that

976
00:40:59,640 --> 00:41:04,320
wikidata uses

977
00:41:01,380 --> 00:41:06,740
um his girlfriend's name started with Q

978
00:41:04,320 --> 00:41:09,540
so that's why he chose the letter Q

979
00:41:06,740 --> 00:41:12,300
so so there is a reason for it

980
00:41:09,540 --> 00:41:14,460
um yeah it's I

981
00:41:12,300 --> 00:41:17,700
I guess not in terms of that initial

982
00:41:14,460 --> 00:41:19,079
development it was developed uh by you

983
00:41:17,700 --> 00:41:20,820
know probably of quite a small number of

984
00:41:19,079 --> 00:41:22,460
developers at Wikimedia Deutschland

985
00:41:20,820 --> 00:41:26,099
which is the the German

986
00:41:22,460 --> 00:41:28,260
chapter of the Wikimedia Foundation

987
00:41:26,099 --> 00:41:30,180
um and yeah I think that was it was just

988
00:41:28,260 --> 00:41:32,520
kind of they they produced it as a sort

989
00:41:30,180 --> 00:41:33,839
of proof of concept and then and then

990
00:41:32,520 --> 00:41:35,339
kind of handed it over to the community

991
00:41:33,839 --> 00:41:37,200
so I think there's a lot of things like

992
00:41:35,339 --> 00:41:38,339
you know qids and so on that aren't

993
00:41:37,200 --> 00:41:40,079
necessarily

994
00:41:38,339 --> 00:41:41,940
you know build up for built from the

995
00:41:40,079 --> 00:41:43,680
ground up by the community but uh but

996
00:41:41,940 --> 00:41:45,359
you know there were sort of handed over

997
00:41:43,680 --> 00:41:46,800
to and managed by the community but but

998
00:41:45,359 --> 00:41:48,720
it was probably just yeah it's developed

999
00:41:46,800 --> 00:41:52,440
by some by you know some

1000
00:41:48,720 --> 00:41:54,180
Foss developers in Germany

1001
00:41:52,440 --> 00:41:56,040
and Wikimedia Deutschland in Germany

1002
00:41:54,180 --> 00:41:58,260
still sort of manages I guess a lot of

1003
00:41:56,040 --> 00:42:00,500
the the administration and so on of that

1004
00:41:58,260 --> 00:42:00,500
project

1005
00:42:10,020 --> 00:42:13,859
um you are of any major projects not

1006
00:42:12,119 --> 00:42:15,900
managed by the Wikimedia Foundation that

1007
00:42:13,859 --> 00:42:18,240
make use of this wikidata database and

1008
00:42:15,900 --> 00:42:21,000
what sorts of use cases are you aware of

1009
00:42:18,240 --> 00:42:24,000
for this thing that likewise aren't

1010
00:42:21,000 --> 00:42:25,740
managed by the Wikipedia Foundation

1011
00:42:24,000 --> 00:42:27,420
yeah that aren't

1012
00:42:25,740 --> 00:42:29,160
um

1013
00:42:27,420 --> 00:42:30,599
so I guess the wiki site one that I

1014
00:42:29,160 --> 00:42:32,460
mentioned that was that was I mean it's

1015
00:42:30,599 --> 00:42:33,839
kind of community it was a completely

1016
00:42:32,460 --> 00:42:35,339
Community Driven thing it's actually I

1017
00:42:33,839 --> 00:42:37,260
think I think it's kind of wound up now

1018
00:42:35,339 --> 00:42:39,839
like it's not it did get some funding

1019
00:42:37,260 --> 00:42:41,940
from the Wikimedia Foundation that um

1020
00:42:39,839 --> 00:42:44,520
uh but but you know simply still got

1021
00:42:41,940 --> 00:42:47,180
ongoing on a volunteer basis

1022
00:42:44,520 --> 00:42:47,180
um can you think of any

1023
00:42:47,300 --> 00:42:52,500
incident Foundation

1024
00:42:49,820 --> 00:42:54,720
the other one I can think of is actually

1025
00:42:52,500 --> 00:42:57,480
that example how it showed of the file

1026
00:42:54,720 --> 00:42:58,680
formats there is um I know there's

1027
00:42:57,480 --> 00:43:01,140
um

1028
00:42:58,680 --> 00:43:03,180
a group who have extended that because

1029
00:43:01,140 --> 00:43:04,800
the wiki data didn't have quite enough

1030
00:43:03,180 --> 00:43:06,180
that they needed so they've gone and

1031
00:43:04,800 --> 00:43:08,819
created their own

1032
00:43:06,180 --> 00:43:10,800
um you know equivalent for file formats

1033
00:43:08,819 --> 00:43:13,440
that you can search

1034
00:43:10,800 --> 00:43:15,359
um yeah but they may well be others

1035
00:43:13,440 --> 00:43:17,060
because yeah it is all open source and

1036
00:43:15,359 --> 00:43:20,400
people are actually not just a typical

1037
00:43:17,060 --> 00:43:22,200
so the uh the info you know those info

1038
00:43:20,400 --> 00:43:24,839
boxes I mean Peter showed the ones that

1039
00:43:22,200 --> 00:43:27,960
were in Wikipedia articles but the uh

1040
00:43:24,839 --> 00:43:30,420
the ones that uh the knowledge graph or

1041
00:43:27,960 --> 00:43:31,140
knowledge boxes that are in Google and

1042
00:43:30,420 --> 00:43:33,420
um

1043
00:43:31,140 --> 00:43:36,839
uh you know iOS and so on you know the

1044
00:43:33,420 --> 00:43:39,960
the Siri knowledge boxes there they they

1045
00:43:36,839 --> 00:43:41,640
are generated from from wikidata so

1046
00:43:39,960 --> 00:43:43,740
um yeah there's some things I guess the

1047
00:43:41,640 --> 00:43:45,720
sort of you know big companies that uh

1048
00:43:43,740 --> 00:43:49,579
millions and millions of people use are

1049
00:43:45,720 --> 00:43:49,579
using it so yeah um

1050
00:43:50,520 --> 00:43:54,599
all right people will have to put a bit

1051
00:43:52,440 --> 00:43:57,180
of core close there if we come to the

1052
00:43:54,599 --> 00:43:59,220
end of the time

1053
00:43:57,180 --> 00:44:01,920
um I'd like you to thank Peter and Alex

1054
00:43:59,220 --> 00:44:04,920
uh it was you this is the sort of talks

1055
00:44:01,920 --> 00:44:06,119
I come to these conferences to hear

1056
00:44:04,920 --> 00:44:07,440
about something I've never heard about

1057
00:44:06,119 --> 00:44:10,680
before or

1058
00:44:07,440 --> 00:44:12,720
I knew about rdf but I had no idea that

1059
00:44:10,680 --> 00:44:14,540
it was put to this use so thank you very

1060
00:44:12,720 --> 00:44:19,820
much to both of you thanks

1061
00:44:14,540 --> 00:44:19,820
[Applause]
