Wikidata-Toolkit: release or snapshot?
by Mike Barretta 18 Aug '15

18 Aug '15

I'm starting to work on a project that will involve me finding specific entities based on names and attributes. In other words, very search-driven. What is the best starting point? Do I go for the 0.4 release or build from the master branch on GitHub? Are snapshots published anywhere? Thanks, Mike

Database of all the people who agree/disagree (e.g. Brexit)
by Hector Perez 18 Aug '15

18 Aug '15

Hi, I'm working on a database of all the people who agree/disagree on issues such the proposed referendum on UK membership of the European Union [1]. I think this is outside the scope of Wikidata (if not, let me know!), but I suppose some people might like it. Would anyone like to help? Kind regards, Hector https://www.linkedin.com/in/hectorperezarenas [1] http://www.agreelist.com/brexit

Wikidata API for fetching images related to a Linked Data Item
by Sachini Herath 14 Aug '15

14 Aug '15

Hi everyone, I’m Sachini Herath, an undergraduate from Sri Lanka. I am working on building Linked Data mapping tools for Drupal 8 as my Google Summer of Code 2015 project. The tools would enable the users to map Drupal entities to Linked Data items. Details of the project can be found in my blog. http://alongthetrail-sachini.rhcloud.com/ To select a Linked Data item, a dropdown element similar to freebase-suggest widget <https://developers.google.com/freebase/v1/search-widget> is being developed, but in a more generic approach so that it can be configured with any Linked Data Provider. For Wikidata, I'm using "*wbsearchentities*" API for querying and " *wbgetentities*" for retrieving information about individual items in json format. However I could not find a way to reconstruct the url of image property for an item, so that I can fetch the image (property P18, P154 etc) for displaying. Are there any APIs or alternative methods to fetch images from Wikidata? I would also like to hear about any optimizations that can be done for the query or alternate APIs. For example an API to return id, label, description and image urls in just one/ few call/s. Thank you Sachini

Data from Netherlands Statistics / CBS on Wikidata?
by Arne Wossink 13 Aug '15

13 Aug '15

Dear list members, Wikimedia Netherlands has been approached by the CBS / Statistics Netherlands (https://en.wikipedia.org/wiki/Statistics_Netherlands), the governmental bureau for statistics, about a possible cooperation to make data available on a (yet to be determined) Wikimedia project. Since this is in a very preliminary stage, we don't have any further details at the moment, but I would be interested to hear if there could be any use of their data on Wikidata, or if similar data from similar institutions elsewhere have already been used. Best, Arne Wossink Projectleider / Project Lead Wikimedia Nederland Tel. +31 (0)6 11000505 *Postadres*: * Bezoekadres:* Postbus 167 Mariaplaats 3 3500 AD Utrecht Utrecht

weekly summary #170
by Lydia Pintscher 09 Aug '15

09 Aug '15

Hey everyone :) Here's what happened around Wikidata over the past week. Hope you're having a good weekend. Discussions - Successful request for oversight rights: Sjoerddebruin Events <https://www.wikidata.org/wiki/Wikidata:Events>/Press/Blogs <https://www.wikidata.org/wiki/Wikidata:Press_coverage> - Wikimedia UK is organizing a Wikidata training session. You can sign up here <https://wikimedia.org.uk/wiki/Wikidata_training_2015>. Other Noteworthy Stuff - Talk pages on Wikidata can now be converted to use Flow. You can request migrating your talk page at d:Wikidata:Flow <https://www.wikidata.org/wiki/Wikidata:Flow>. - Mix-n-Match <https://tools.wmflabs.org/mix-n-match> got a bunch of new catalogs for you to match up with Wikidata. Currently matching is happening at about 500 items per day. Pretty sweet :) - @happybirthdayauthors <https://twitter.com/happybdauthors> is a new Twitter account posting reading suggestions based on Wikidata data. - Arbitrary access <https://www.wikidata.org/wiki/Wikidata:Arbitrary_access> is rolling out to a large number of wikis over the next two weeks. - Duplicity <https://tools.wmflabs.org/wikidata-todo/duplicity.php> can help you match up unlinked Wikipedia articles to a Wikidata item. Did you know? - Newest properties: Erdős number <https://www.wikidata.org/wiki/Property:P2021>, worldfootball.net ID <https://www.wikidata.org/wiki/Property:P2020>, AllMovie artist ID <https://www.wikidata.org/wiki/Property:P2019>, Teuchos ID <https://www.wikidata.org/wiki/Property:P2018>, isomeric SMILES <https://www.wikidata.org/wiki/Property:P2017>, Catalogus Professorum Academiae Groninganae id <https://www.wikidata.org/wiki/Property:P2016>, Hansard ID <https://www.wikidata.org/wiki/Property:P2015> Development - Made some small changes to the style of the edit warning and sitelinks so they are easier to notice and understand - Added error messages for Special:GoToLinkedPage and Special:ItemByTitle so you get a useful message in case no result is found - The Entity Selector now displays alias in brackets behind label - The number of entities loaded via the {{#property:…}} parser function and via Lua will be reported in the “Parser profiling data” (which can be found below a page preview or within the Html of a page) - Prepared for next rounds of arbitrary access rollout - Investigated growing lag of dispatching of changes to Wikipedia and co. We'll need to investigate further and change things so the lag between an edit on Wikidata and it being send to the Wikipedias and other projects is not too high. - Added the property ID to Special:ListProperties - Moved two extensions (Wikidata.org and WikimediaBadges) from Github to Gerrit. More will follow. - We'd like to drop a database table. <https://lists.wikimedia.org/pipermail/wikidata/2015-August/006847.html> Discussion is ongoing.

how to get WD item -> enwiki sitelinks?
by Vladimir Alexiev 07 Aug '15

07 Aug '15

Hi folks! We need a full mapping of WD item -> enwiki sitelinks. 1. We extracted from Dbpedia 2015-04 all statements of the form <http://dbpedia.org/resource/Northern_Ireland> <http://www.w3.org/2002/07/owl#sameAs> <http://wikidata.org/entity/Q26> And the count is 5882410 2. Checked with WDQ: https://wdq.wmflabs.org/api?q=link[enwiki]&noitems=1 "items":6263098 6.08% are missing from DBpedia. That's a lot How to get them from Wikidata? 3. WDQ doesn't seem to return sitelinks. https://wdq.wmflabs.org/api?q=link[enwiki]&props=enwiki returns just item numbers 4. The SPARQL endpoint doesn't seem to have them: http://wdqs-beta.wmflabs.org/ prefix schema: <http://schema.org/> select * {?x schema:about ?y} returns nothing. https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#WDQS_data_d ifferences says "5. Depending on the instance of the service, multi-language labels and sitelinks may or may not be supported." I think this service doesn't have sitelinks: is there one that has them?
