Lydia, May be you could create and maintain http://meta.wikimedia.org/wiki/Wikidata/Status_updates/ as a menu page for all the monthly reports?

[Wikidata-l] Linked Data Cup - Deadline Extension until April 25th, 2012
by Sebastian Hellmann 13 Apr '12

13 Apr '12

(apologies for multiple posts; please forward; please email i-challenge2012_a_t_easychair.org for questions) ******************** NEWS: - Deadline extension until April 25th, 2012 - The total amount of 2,000 EUR (sponsored by Wolters Kluwer) will be awarded in prizes and split among the most promising applications. - Linked Data Cup Board updated: http://i-challenge.blogs.aksw.org/chairs-committee ******************** Linked Data Cup 2012 http://i-challenge.blogs.aksw.org/ co-located with the I-Semantics 2012 Graz, Austria, 5 - 7 September 2012 http://www.i-semantics.at ******************** The yearly organised Linked Data Cup (formerly Triplification Challenge) awards prizes to the most promising innovation involving linked data. Four different technological topics are addressed: triplification, interlinking, cleansing, and application mash-ups. The Linked Data Cup invites scientists and practitioners to submit novel and innovative (5 star) linked data sets and applications built on linked data technology. Although more and more data is triplified and published as RDF and linked data, the question arises how to evaluate the usefulness of such approaches. The Linked Data Cup therefore requires all submissions to include a concrete use case and problem statement alongside a solution (triplified data set, interlinking/cleansing approach, linked data application) that showcases the usefulness of linked data. Submissions that can provide measurable benefits of employing linked data over traditional methods are preferred. Note that the call is not limited to any domain or target group. We accept submissions ranging from value-added business intelligence use cases to scientific networks to the longest tail [1] of information domains. The only strict requirement is that the employment of linked data is very well motivated and also justified (i.e. we rank approaches higher that provide solutions, which could not have been realised without linked data, even if they lack technical or scientific brilliance). The total amount of 2,000 EUR (sponsored by Wolters Kluwer) will be awarded in prizes and split among the most promising applications. Evaluation Criteria =================== The submissions will be initially evaluated with a well-known five star ranking system [2]. Furthermore, entries will be assessed according to the extent to which they 1. motivate the relevancy of their use case for their respective domain; 2. justify the adequacy of linked data technologies for their solution; 3. demonstrate that all alternatives to linked data would have resulted in an inferior solution; 4. provide an evaluation that can measure the benefits of linked data Topics ====== Ideas for topics include (but are not limited to): * Improving traditional approaches with help of linked data * Linked data use in science and education * Linked data supported multimedia applications * Linked data in the open source context * Web annotation * Generic applications * Internationalization of linked data * Visualization of linked data * Linked government data * Business models based on linked data * Recommender systems supported by linked data * Integrating microposts with linked data * Distributed social web based on linked data * Linked data sensor networks Submission and Reviewing ======================== Submissions to the Linked Data Cup will be reviewed by members of the Linked Data Cup Board and invited experts from the Linked Data community. Submissions should consist of 4 pages and must be original and must not have been submitted for publication elsewhere. Papers should follow the ACM ICPS guidelines for formatting as accepted submissions will be published in the I-SEMANTICS 2012 proceedings in the digital library of the ACM ICP series. Please read the submission page[a] for detailed information on how to submit. Important Dates (Linked Data Cup) 1. Paper Submission Deadline: April 25, 2012 2. Notification of Acceptance: May 21, 2012 3.

[Wikidata-l] Hello from the YAGO team
by Fabian M. Suchanek 13 Apr '12

13 Apr '12

Dear Wikidata team, I am writing on behalf of the YAGO team at the Max Planck Institute for Informatics in Saarbruecken [1]. We have heard about the Wikidata project, and we are very excited to learn that you aim to launch a free knowledge base in the spirit of Wikipedia. We would like to get in touch with you -- also to see whether or how we could help on the long run. Let me briefly tell you what we have on our side: As you might know, YAGO is knowledge graph that has been extracted automatically from the infoboxes and categories of Wikipedia. We have evaluated YAGO manually and achieved a precision of 95%, meaning that statistically speaking, only 5 out of 100 statements in the knowledge graph are extracted wrongly. We also have a link of the Wikicategories to the WordNet taxonomy (again with 95% precision), and type checking methods for the extracted statements. Should these things ever be useful to you, we would be happy to help. I will be at the WWW conference next week. In case some of you are there, too, I'd be happy to get in touch to learn more about your current work. Thanks Fabian [1] http://yago-knowledge.org -- Thanks Fabian -- Fabian online: http://suchanek.name

Apparently people like to criticize :) To discuss something fundamental is not criticizing. This article raises a problem we know very well à the different (linguistic, telecom, network) strata below (diversity, orthotypography, normalization, informatics, canonization, globalization, internationalization, etc. ) which now touches the semantical and intellectual strata. Engineering issues, as discussed here, are for the technical processes to work better. The problem is to determine what "better" societaly means in an "antropobotical" society (persons/robots) like ours - broadly influenced by its daily experience of Wikipedia. This leads to fundamental questions on the Freedom of Knowledge. The difficulty is the resulting ethical/technical loop and the impact on engineering orientations. jfc

[Wikidata-l] JSON-LD Provenance use case
by Gregg Kellogg 12 Apr '12

12 Apr '12

I updated the JSON Talk page [1] with an example of using the JSON-LD named-graph syntax to express provenance information about some facts, based on a discussion of the use case in the W3C RDF Working Group [2] trying to express the following: ParisFact1 expresses "Paris locatedIn France ." ParisFact1 hasReference EncyclopediaBritannica, Wikipedia, Brockhaus. ParisFact2 Paris hasPopulation 7000000^^int ParisFact2 hasReference Wikipedia The JSON-LD looks like the following: { "@context": { "rdf": "http://www.w3.org/1999/02/22-rdf-syntax-ns#", "ex": "http://example.org/", "xsd": "http://www.w3.org/2001/XMLSchema#", "ex:locatedIn": {"@type": "@id"}, "ex:hasPopulaton": {"@type": "xsd:integer"}, "ex:hasReference": {"@type": "@id"} }, "@graph": [ { "@id": "http://example.org/ParisFact1", "@type": "rdf:Graph", "@graph": { "@id": "http://example.org/location/Paris#this", "ex:locatedIn": "http://example.org/location/France#this" }, "ex:hasReference": ["http://www.britannica.com/", "http://www.wikipedia.org/", "http://www.brockhaus.de/"] }, { "@id": "http://example.org/ParisFact2", "@type": "rdf:Graph", "@graph": { "@id": "http://example.org/location/Paris#this", "ex:hasPopulation": 7000000 }, "ex:hasReference": "http://www.wikipedia.org/" } ] } Which could be expressed in TriG as: @prefix ex: <http://example.org/> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . { ex:ParisFact1 a rdf:Graph; ex:hasReference <http://www.britannica.com/>, <http://www.wikipedia.org/>, <http://www.brockhaus.de/> . ex:ParisFact2 a rdf:Graph; ex:hasReference <http://www.wikipedia.org/> . } ex:ParisFact1 { <http://example.org/location/Paris#this> ex:locatedIn <http://example.org/location/France#this> . } ex:ParisFact2 { <http://example.org/location/Paris#this> ex:hasPopulation 7000000 . } Note that JSON-LD recently added support for named graphs [3].

[Wikidata-l] Wikidata FAQ translated, and proposing my help.
by Nicolas Torzec 12 Apr '12

12 Apr '12

Dear Wikidata, I just wanted to let you know that I have spent a couple of hours translating the Wikidata FAQ into French. => See http://meta.wikimedia.org/wiki/Wikidata/FAQ/fr I also went after the first Wikidata documentation and published an introduction to the project, as a proof that I did my due diligence :) => http://zecdata.com/2012/04/09/wikidata-one-common-source-of-structured-data… I would be happy to help and collaborate if needed. (I have worked on various related topics at Yahoo! Labs and other places over the past 10+ years. So I may be of some help. Feel free to look me up on LinkedIn) Best, Nicolas.
