Fwd: SPARQL users' survey
by Andy Mabbett 20 Mar '18

20 Mar '18

Some of you may be interested in this, from the W3C's Semantic web mailing list: ---------- Forwarded message ---------- From: Paul Warren <paul.w.warren(a)btinternet.com> Date: 20 March 2018 at 15:27 Subject: SPARQL users' survey To: semantic-web(a)w3.org Dear Semantic Web group members I have created a questionnaire to help understand how people are using SPARQL. As many of you will know, there have been a number of analysis of SPARQL query logs, which offer some insight into the nature of queries but little insight into the requirements and thought processes of those initiating the queries. This questionnaire attempts to get a better insight into how SPARQL is being used and what difficulties are being experienced. The questionnaire, which takes around 20 minutes, is available at: https://openuniversity.onlinesurveys.ac.uk/sparql-survey All responses to this survey are extremely valued. The results will be made available in the public domain and this group will be notified. The closing date for the questionnaire is 14th April. Many thanks Paul Warren, Knowledge Media Institute, Open University, U.K. -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk

Your ideas of projects for the Wikimedia hackathon
by Léa Lacroix 16 Mar '18

16 Mar '18

Hello all, This year, the Wikimedia hackathon <https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2018> will take place on 18-20 May in Barcelona. Several Wikidata volunteers and members of the development team will attend. Like last year, there will also be a documentation sprint <https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2018/Documentation> where people can work on improving documentation. - If you are attending, which Wikidata-related projects do you plan to work on? - Do you have ideas of features or fixes that should be worked on during the hackathon? - Are there documentation pages that need to be improved? (you can also participate remotely) Feel free to add your ideas here <https://www.wikidata.org/wiki/Wikidata:Project_chat#Your_ideas_of_projects_…>, you can link to Phabricator tickets. Note that the hackathon is only a 3-days event and some projets need a longer time to be achieved ;) Cheers, -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.

Election data
by Amir E. Aharoni 14 Mar '18

14 Mar '18

Hi, Different countries have different processes for elections: registration of political parties and candidates, the form of the ballot, the system for counting the votes and dividing the seats in the legislature, etc. I was surprised not to find almost any data about electoral history for Israeli political parties. I also couldn't find it for other famous political parties around the world, like CDU (Germany), Syriza (Greece), or GOP (U.S.). Representing it in Wikidata is somewhat challenging because of the differences between the countries, because parties, candidates lists, and fractions are different things, etc. But only somewhat: it definitely doesn't sound impossible. Is there any country whose electoral processes and history are represented comprehensively in Wikidata? If not, were there any attempts to even discuss it? Thanks! -- Amir Elisha Aharoni · אָמִיר אֱלִישָׁע אַהֲרוֹנִי http://aharoni.wordpress.com ‪“We're living in pieces, I want to live in peace.” – T. Moore‬

Generating info-boxes from Wikidata: the importance of values!
by Aidan Hogan 13 Mar '18

13 Mar '18

Hi all, Tomás and I would like to share a paper that might be of interest to the community. It presents some preliminary results of a work looking at fully automated methods to generate Wikipedia info-boxes from Wikidata. The main focus is on deciding what information from Wikidata to include, and in what order. The results are based on asking users (students) to rate some prototypes of generated info-boxes. Tomás Sáez, Aidan Hogan "Automatically Generating Wikipedia Infoboxes from Wikidata". In the Proceedings of the Wiki Workshop at WWW 2018, Lyon, France, April 24, 2018. - Link: http://aidanhogan.com/docs/infobox-wikidata.pdf We understand that populating info-boxes is an important goal of Wikidata and hence we thought we'd share some lessons learned. Obviously a lot of work is being put into populating info-boxes from Wikidata, but the main methods at the moment seem to be template-based and require a lot of manual labour; plus the definition of these templates seems to be a difficult problem for classes such as person (where different information will have different priorities for people of different professions, notoriety, etc.). We were just interested to see how far we could get with a fully automated approach using some generic ranking methods. Also we thought that something like this could perhaps be used to generate a "default" info-box for articles with no info-box and no associated template mapping. The paper presents preliminary results along those lines. One interesting result is that a major factor in the evaluation of the generated info-boxes was the importance of the value. For example, Barack Obama has lots of awards, but perhaps only something like the Nobel Peace Prize might be of relevance to show in the info-box (<- being intended as an illustrative example rather than a concrete assertion of course!). Another example is that sibling might not be an important attribute in a lot of cases, but when that sibling is Barack Obama, then that deserves to be in the info-box (<- how such cases could be expressed in a purely template-based approach, we are not sure, but it would seem difficult). We assess the importance of values with PageRank. Assessing the importance not only of attributes, but of values, turned out to be a major influence on how highly our evaluators assessed the quality of the generated info-boxes. This initial/isolated observation might be interesting since, to the best of our understanding, the current wisdom on populating info-boxes from Wikidata focuses on what attributes to present and in which order, but does not consider the importance of values (aside from the Wikidata rank feature, which we believe is more intended to assess relevance/timeliness, than importance). Hence one of the most interesting (and surprising, for us at least) results of the work is to suggest that it appears to be important to rank *values* by importance (not just attributes) when considering what information the user might be interested in. (There are limitations to PageRank measures, however, in that they cannot assess, for example, the importance of a particular date, or, more generally, datatype values.) In any case, we are looking forward to presenting these results at the Wiki Workshop at WWW 2018, and any feedback or thoughts are welcome! Cheers, Aidan

How to eliminate items not having a label in a particular language from the Wikidata query results
by abdelwaheb turki 12 Mar '18

12 Mar '18

Dear Mr. or Ms., I thank you for your efforts. I have written the following query to find the languages that have a label in Tunisian in Wikidata: SELECT ?_tre_humain ?_tre_humainLabel WHERE { SERVICE wikibase:label { bd:serviceParam wikibase:language "aeb-arab". } ?_tre_humain wdt:P31 wd:Q34770. } However, I found that many languages not having a label in Tunisian are sorted as well. For these languages, the featured label is the Wikidata ID of the language. I ask about how to eliminate these languages from the results of my wikidata query. Yours Sincerely, Houcemeddine Turki
