[Wikidata-l] Access other "In Other Languages"
by Derric Atzrott 20 Aug '14

20 Aug '14

Is there a better way to get at more items in the "In Other Languages" section than to change the interface language with ?setlang= ? I had an item I wanted to give the name in Italian for (it was mentioned in the English Wikipedia article) and I discovered that the only way I could find to get access to the form field for Italian name was to change Wikidata to Italian. I didn't see anything immediately upon Googling. Thank you, Derric Atzrott

[Wikidata-l] Come to present Wikidata in Finland!
by Susanna Ånäs 20 Aug '14

20 Aug '14

Wikimedia Finland calls for a Wikidata developer/advocate to present Wikidata at Avoin Suomi 2014 fair http://avoinsuomi2014.fi/ September 15–16. The event is organized by the Prime Minister's Office in collaboration with several public sector actors and open knowledge organizations. Wikimedia Finland has a booth, and will present projects in GLAM and education, and the Wikimedia sister projects with focus on Wikidata. To take advantage of the presence of the skilled wikidatan, we plan to arrange a Wikidata hands-on workshop before or after the event. The closer you are to Finland the better, but Finnish language is not a requirement. Please contact susanna.anas(a)wikimedia.fi if you are interested. You may forward this to a person you know might be interested. Looking forward to talking with you!

[Wikidata-l] A note on "instance of:Wikipedia disambiguation page"
by Markus Krötzsch 20 Aug '14

20 Aug '14

Hi all, We have a lot of statements saying that something is an instance of a "Wikipedia disambiguation page" (Q4167410). Unfortunately, this kind of information says something about a particular Wikipedia article in a particular language, and often is not true for other languages. Moreover, even if there is a language where the according article is marked as disambiguation page, it is still common that the page gives a description of a real item. Example (bad use of instance of:Wikipedia disambiguation page) ============================================================== https://www.wikidata.org/wiki/Q247819 (VW Polo) Enwiki (like many languages) has a normal article here that is not a disambiguation page. It says "The Volkswagen Polo is a supermini car produced by the German manufacturer Volkswagen". That's very different from "The Volkswagen Polo is a disambiguation page." Even Wikipedias where the VW-Polo article is marked as disambiguation page do not claim that the thing they are talking about is the disambiguation page. For instance, frwiki has the article in Catégorie:Homonymie, yet it says: "Volkswagen Polo est une automobile, de la gamme des polyvalentes, de la marque allemande Volkswagen" Again, it is not said that VW Polo is a disambiguation page, even though the page (not the car) is marked as one. Proper use of instance of:Wikipedia disambiguation page ======================================================= Now there are also many proper disambiguation pages. They do not have a joint concept, other than the ambiguous title in a particular language. Examples: https://en.wikipedia.org/wiki/Jaguar_(disambiguation) and, entertainingly: https://en.wikipedia.org/wiki/Disambiguation_(disambiguation) An item that is "instance of:Wikipedia disambiguation page": * should not have sitelinks to pages that are not disambiguation pages (an item can either be about a Wikipedia page or about a car, but these should be kept separate), * should always use the exact page title as the label (because this is the real label of the page; the page "Jaguar (disambiguation)" is not called "Jaguar" by anybody), * should hardly have any statements at all, since there is almost nothing that you can truthfully say about a group of pages in many different languages, and since we want to avoid project-specific statements (that's one reason we have badges as part of site links). Whether disambiguation pages should have more than a single sitelink at all is another question. In my view, if we are talking about a "page", it is not the same page in French as it is in English (most properties that pages could naturally have, such as authors, language, creation date, etc. apply to a single page only). However, I can see that it is practical to group such pages nonetheless. Conclusion ========== It would be nice if somebody could analyse this problem in more detail (how many of our "disambiguation page" items have statements that are obviously not about a page but about a car make, animal, etc.). We might need some manual effort to clean this up (basically, a kind of un-merging game). The immediate conclusion is that we need to be much more careful importing this type of information from one Wikipedia, since it is (by its very nature) not project-independent and not universal across languages. Cheers, Markus

[Wikidata-l] Announce: WikiProject Structured Data for Commons
by James Heald 20 Aug '14

20 Aug '14

https://www.wikidata.org/wiki/Wikidata:WikiProject_Structured_Data_for_Comm… The aim of of the WikiProject Structured Data for Commons is: * To develop templates that draw directly on Wikidata (and in future also on Commons Wikibase), that will act as drop-in replacements for templates currently in use on Commons. * To develop new templates that can bring new functionality to Commons filepages (eg "topics" listings) * To support the cataloguing of particularly idiosyncratic templates currently in use on Commons (eg institutional credit/backlink templates, and other source templates), and try to produce more generalised, standardised forms that can draw on Wikidata. * To work with other WikiProjects on Wikidata to understand, document and develop the data models on Wikidata, and make sure that they are sufficient to accommodate the needs of GLAM organisations and others currently or in future uploading or maintaining metadata on Commons. * To start to port existing such data that can be represented in structured form, and is appropriate to do so, from Commons to Wikidata * To examine the divide between what should be stored on Wikidata and what should be stored on the proposed Commons Wikibase. * To support, as a user-space community, the work of the staffers developing Commons Wikibase and other aspects of the Foundation initiative for Structured Data for Commons in any way we can. Sign up now! Talk-page comments, or wholescale re-editing, of this essay at https://commons.wikimedia.org/wiki/Commons:Wikidata/How_GLAMs_can_help_the_… also very welcome. -- J.

[Wikidata-l] new features deployed \o/
by Lydia Pintscher 20 Aug '14

20 Aug '14

Hey folks :) As announced last week we just deployed a number of new features. Those are: * Wikinews is now able to manage its sitelinks via Wikidata. https://www.wikidata.org/wiki/Wikidata:Wikinews for questions/coordination/... * Wikidata is now also its own client. This means you can for example add a sitelink to Wikidata:Help to the item for all main help pages. You are able to make use of the data in items on other pages in Wikidata with Lua. (Arbitrary access has been enabled for Wikidata for this but when data in an item changes we will not be able to purge the page using the data yet.) * Sitelinks for projects with just one sitelink in the group (like Commons, Wikidata and in the future Meta for example) are now grouped together in one sitelink group. * Badges for good and featured articles can be stored on Wikidata right next to the sitelink. We have badges for featured and good articles. More can be added on request later. Thanks to Bene* and lazowik for this feature. * Redirects between items can be created. When two items are merged one of them can be turned into a redirect. This way our identifiers can be considered much more stable by 3rd parties for example. It also makes it unnecessary to delete duplicate items. This will reduce the workload of our admins considerably. * We have the new datatype monolingual text. This allows you to make statements with a string and an associated language. Known issues/limitations: * Redirects can so far only be created via the API * Arbitrary access on Wikidata to the data on Wikidata itself is only possible via Lua. The parser function still needs to be adapted. * Badges can not yet be shown on the Wikipedias etc. This will follow next week. * Diffs for badges changes have a link to a wrong target (https://bugzilla.wikimedia.org/show_bug.cgi?id=69758) Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

[Wikidata-l] Linking to Redirects
by Derric Atzrott 19 Aug '14

19 Aug '14

There was an RFC last year about linking interwiki linking to redirect pages on the various Wikipedias: https://www.wikidata.org/wiki/Wikidata:Requests_for_comment/A_need_for_a_re… ion_regarding_article_moves_and_redirects#new_Proposal_zero Any idea what ever happened to that? Was a bug opened eventually, was there another discussion where it was decided not to do it? Is it still just a work in progress? Thank you, Derric Atzrott

[Wikidata-l] badges support on Wikidata
by Lydia Pintscher 19 Aug '14

19 Aug '14

Hey folks :) Just an update on badges support on Wikidata. We will be rolling out support for badges on Wikidata on August 19th. At this point you will be able to store the information that a given article is a good or featured article on English Wikipedia for example. More badges can be added on request. One week later we will enable showing those badges on Wikipedia/Wikisource/Wikiquote in the language links in the sidebar. If your Wikipedia wants them to be removed from the wikitext please get in touch with Amir. He has a bot to do it for you. You can try out the Wikidata-side of it on our test system: https://test.wikidata.org/wiki/Q296 Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

[Wikidata-l] 2nd LIDER Hackathon Preparation call: today at 14:00
by Sebastian Hellmann 19 Aug '14

19 Aug '14

Apologies for cross-posting. This is a kind reminder about the weekly Google Hangout to prepare for the LIDER Hackathon in Leipzig (Sept 1st). The preparation Hangouts will happen each Tuesday at 2pm Leipzig time until the event. Links to join can be found here: http://mlode2014.nlp2rdf.org/hackathon/ You are still able to submit topics for hacking. Please add them to this document: https://docs.google.com/document/d/13riJU5LY50Q6AeHzlkIqln9enlq9a1EDsOyp6C4… or send an email to Bettina Klimek <klimek(a)informatik.uni-leipzig.de> Currently we have the confirmed topics below. Furthermore we have experts available that will help you to get in touch with Linked Data and RDF and help you to bring your own tools to the Semantic Web world. T7: [Confirmed] Roundtrip conversion from TBX2RDF and back The idea of this is to work on a roundtrip conversion from the TBX standard for representing terminology to RDF and back. The idea would be to build on the existing code at bitbucket: https://bitbucket.org/vroddon/tbx2rdf Potential industry partner: TILDE (Tatiana) Source code: https://bitbucket.org/vroddon/tbx2rdf TBX Standard: http://www.ttt.org/oscarstandards/tbx/ Contact person: Philipp Cimiano, John McCrae, Victor Rodriguez-Doncel T8: [Confirmed] Converting multilingual dictionaries as LD on the Web The experience on the creation of the Apertium RDF <http://linguistic.linkeddata.es/apertium/>dictionaries will be presented. Taking as starting point a bilingual dictionary represented in LMF/XML, a mapping into RDF was made by using tools such as Open Refine <http://openrefine.org/>. From each bilingual dictionary three components (graphs) were created in RDF: two lexicons and a translation set. The used vocabularies were lemon <http://lemon-model.net/>for representing lexical information and the translation module <http://linguistic.linkeddata.es/def/translation/>for representing translations. Once they were published on the Web, some immediate benefits arise such as: automatic enrichment of the monolingual lexicons each time a new dictionary is published (due to the URIs ruse), simple graph-based navigation across the lexical information and, more interestingly, simple querying across (initially) independent dictionaries. The task could be either to reproduce part of the Apertium generation process, for those willing to learn about lemon and about techniques for representing translations in RDF, or to repeat the process with other input data (bilingual or multilingual lexica) provided by participants. Contact person: Jorge Gracia T9: [Confirmed] Based on the NIF-LD output of Babelfy we can try to deploy existing RDF visualizations out of the box and query the output with SPARQL Babelfy <http://babelfy.org/>is a unified, multilingual, graph-based approach to Entity Linking and Word Sense Disambiguation. Based on a loose identification of candidate meanings, coupled with a densest subgraph heuristic which selects high-coherence semantic interpretations, Babelfy is able to annotate free text with with both concepts and named entities drawn from BabelNet <http://www.babelnet.org/>’s sense inventory. The task consists of converting text annotated by Babelfy into RDF format. In order to accomplish this, participants will start from free text, will annotate it with Babelfy and will eventually make use of the NLP2RDF NIF module <http://site.nlp2rdf.org/>. Data can also be displayed using visualization tools such as RelFinder <http://www.visualdataweb.org/relfinder/relfinder.php>.

[Wikidata-l] Fwd: Compare person data
by Gerard Meijssen 19 Aug '14

19 Aug '14

Hoi, Amir has created functionality that compares data from en.wp de.wp and it.wp. It is data about "humans" and it only shows differences where they exist. It compares those four Wikipedias with information in Wikidata. The idea is that the report will be updated regularly. The problem we face is: what should it actually look like. Should it just splatter the info on a page or is more needed. At this time we just have data [1]. Please help us with something that works easily for now. Once we have something, it can be prettified and more functional. Thanks, GerardM [1] http://paste.ubuntu.com/8079742/

Sure, the list should be the result of the first automatic matching attempts and currently the only human validator is the GSoC student. > Is there any way that we can collaborate to increase the number of matches > or does it have to do with qualifiers? Of course, and we definitely should collaborate! Both the Wikidata and the DBpedia communities can strongly benefit from each other. The DBpedia ontology is based on a wiki as well, i.e., the mappings wiki [1]. All you have to do is to create an account and request editor rights on our mailing list [2] (please subscribe first). > And do you plan to document 1:1 > matches on your OntologyProperty namespace? Sure, we will add an 'owl:equivalentProperty' assertion pointing to the matching Wikidata property. BTW, it should be partially implemented for classes too, e.g. 'Person' [3]. This is reflected in the data. See for instance the 'rdf:type' property in this Italian chapter example [4], which has links to Wikidata classes. Cheers!
