[Wikidata-l] Platypus, a speaking interface for Wikidata
by Thomas Tanon 25 Feb '15

25 Feb '15

Hello everyone, I and some other students from the ENS de Lyon have created a query answering tool [1] based on Wikidata. Its goal is to provide an improved version of Wiri [2] with advanced natural language processing techniques. Thanks to Lydia there is a now a blog post on wikimedia.de blog to introduce it: https://blog.wikimedia.de/2015/02/23/platypus-a-speaking-interface-for-wiki… A side feature that may especially interest the Wikidata community is the power user's query syntax [3] that allows to do easily queries on Wikidata content. It is currently powered by WikidataQuery [4] but we should switch to our own query engine [5] in a few days.

[Wikidata-l] ViziData
by Georg Wild 25 Feb '15

25 Feb '15

Hello Wikidatans, I'd like to quickly introduce you ViziData [1], a data visualization app that I wrote as part of my bachelors thesis last year and will work on improving in the coming months. It displays the geographical and temporal location of events (currently only births and deaths of humans are available in the prototype). The data is extracted from Wikidata with Wikidata Toolkit. The tool means to show an interesting use of the data in Wikidata (especially larger amounts) and can also give an impression about the quality and completeness of the collected data on a larger scale. Planned improvements include: * other datasets to display * more efficient and useful timeline widget * embedded tile map for orientation * canvas rendering for performance * information about events (e.g. listing persons who were born at selected point) * code quality :S The source is available on Github under the MIT license [2] and the corresponding paper can be read online [3] (in German only though). If you have any questions or concerns about this project, feel free to contact me :] Georg [1] http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/ [2] https://github.com/gordelwig/ViziData [3] https://ddll.inf.tu-dresden.de/web/Thema3412 (German only) -- ☘ excellentiā excelsiōre ☘

[Wikidata-l] Using mw.wikibase.getEntity? Read on!
by hoo 20 Feb '15

20 Feb '15

Hi Everyone, We provide an interface for the Scribunto extension (Lua modules) in Wikibase for quite some time now. Our integration with Scribunto was very basic initially and not future proof enough for things like arbitrary access or very big items. Due to that we at some point deprecated the old Lua function to access entities mw.wikibase.getEntity[0] in favor of mw.wikibase.getEntityObject[1] which is much more than just a plain Lua table and allowed us to introduce various convenience functions and to improve performance. We plan to extend on that in the near future to make arbitrary access possible, especially from a performance point of view. As that's not possible with the legacy mw.wikibase.getEntity function it would be nice if you could replace all of your usages of that function with the new function. Migrating shouldn't be hard, but there are two breaking changes between the output format of the two functions which you need to be aware of and potentially adopt your modules to. First of all the old entity format, as obtained from mw.wikibase.getEntity, includes all claims twice once with upper and once with lower case keys (so both "P123" and "p123" are present as keys). That has been removed in the new format in favor of just upper case keys ("P123"). The other breaking change is that in the new entity format the Lua tables are no longer numbered from 0 on, but from 1 on (which is the native Lua table enumeration). You can find a list of all Lua modules (potentially) using the old function sorted by number of transclusions on https://phabricator.wikimedia.org/P272. Cheers, Marius [0]: https://www.mediawiki.org/wiki/Extension:Wikibase_Client/Lua#mw.wikibase.ge… [1]: https://www.mediawiki.org/wiki/Extension:Wikibase_Client/Lua#mw.wikibase.ge…

[Wikidata-l] Missing dumps with history
by Lukas Benedix 20 Feb '15

20 Feb '15

Hi, Since the dumps without history show a tremendous increase in size, I assume something interesing happened in the recent history: 3.5G Oct 12 10:13 wikidatawiki-20141009-pages-articles.xml.bz2 3.9G Nov 9 10:11 wikidatawiki-20141106-pages-articles.xml.bz2 3.9G Dec 8 05:25 wikidatawiki-20141205-pages-articles.xml.bz2 4.6G Jan 16 23:27 wikidatawiki-20150113-pages-articles.xml.bz2 But there seems to be a problem with the latest dumps with complete history, so it is not possible to investigate this events. The last dump that is available is: wikidatawiki-20141106-pages-meta-history.xml.bz2 Can someone have a look at the dump process and tell we when the next actual dump with history will be available? Lukas

[Wikidata-l] interlanguage links not updated on the mobile site
by Amir E. Aharoni 19 Feb '15

19 Feb '15

[ Crossposting to mobile and wikidata lists. Sorry about the inconvenience. You may want to use "Reply to all". ] Hi, The articles about the musician Eviatar Banai in Hebrew and English Wikipedias exist fr years. On 2015-02-04 I created one in Catalan. Today I created one in Russian. If I look at the Hebrew Wikipedia, I see interlanguage links to Catalan, English and Russian: https://he.wikipedia.org/wiki/%D7%90%D7%91%D7%99%D7%AA%D7%A8_%D7%91%D7%A0%D… *Now here's the really fun part:* If I look at the mobile Hebrew Wikipedia, I only see an interlanguage link to English. https://he.m.wikipedia.org/wiki/%D7%90%D7%91%D7%99%D7%AA%D7%A8_%D7%91%D7%A0… I guess that it's a caching issue, but: 1. A link from Hebrew to Catalan doesn't appear after *two weeks*. 2. It's quite surprising that links for mobile and for desktop are cached separately. #2 may be OK if it helps with performance or something, but #1 seems exaggerated to me. Does it really have to take two weeks or is it a bug? Thanks :) -- Amir Elisha Aharoni · אָמִיר אֱלִישָׁע אַהֲרוֹנִי http://aharoni.wordpress.com ‪“We're living in pieces, I want to live in peace.” – T. Moore‬
