[Wikidata-l] new search backend ready for testing
by Lydia Pintscher 06 Nov '13

06 Nov '13

Hey everyone, Progress! We now have the long awaited new search backend up and running for testing on Wikidata. It will still need some tweaking but please do try it and give feedback. It is running in parallel to the old one. You will need to visit a special page to use it: https://www.wikidata.org/w/index.php?search=athens&button=&title=Special%3A… Please let me know about any issues you can still find with it so this so we can soon make it the default. Thanks to Chad and Katie for working on this. Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

Hey everyone, The next sister project to get language links via Wikidata is Wikisource. We're currently planning this for January 13. The coordination is happening at https://www.wikidata.org/wiki/Wikidata:Wikisource On this page we're also looking for ambassadors to help spread the messages to the different language editions of Wikisource. Please help if you can. Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

[Wikidata-l] classes and qualifiers
by Thomas Douillard 06 Nov '13

06 Nov '13

Hey, I got an ontology question. Classes are, in semantic web framework and their foundations like Description Logic, if I'am not wrong, something like a lohic predicate that intensionaly or extentionaly defines the properties of their instances. They are usually not qualified, but in Wikidata, as of now they are properties like the others, who can also be qualified. So the question is : could we use qualifier on classes to add predicates on the class definition ? For example if <George Bush> is an instance of <United States President> [<from> 1980 <to> 1984] (random years), this would mean that the instanciation add some predicates on the other predicates we have on the <president of the united states> ? Just a random thought, I just realise I just qualified the instanciation, not the class itself. --TomT0m

[Wikidata-l] Questions about statement qualifiers
by Antoine Zimmermann 05 Nov '13

05 Nov '13

Hello, I have a few questions about how statement qualifiers should be used. First, my understanding of qualifiers is that they define statements about statements. So, if I have the statement: Q17(Japan) P6(head of government) Q132345(Shinzō Abe) with the qualifier: P39(office held) Q274948(Prime Minister of Japan) it means that the statement holds an office, right? It seems to me that this is incorrect and that this qualifier should in fact be a statement about Shinzō Abe. Can you confirm this? Second, concerning temporal qualifiers: what does it mean that the "start" or "end" is "no value"? I can imagine two interpretations: 1. the statement is true forever (a person is a dead person from the moment of their death till the end of the universe) 2. (for end date) the statement is still true, we cannot predict when it's going to end. For me, case number 2 should rather be marked as "unknown value" rather than "no value". But again, what does "unknown value" means in comparison to having no indicated value? Third, what if a statement is temporarily true (say, X held office from T1 to T2) then becomes false and become true again (like X held same office from T3 to T4 with T3 > T2)? The situation exists for Q35171(Grover Cleveland) who has the following statement: Q35171 P39(position held) Q11696(President of the United States of America) with qualifiers, and a second occurrence of the same statement with different qualifiers. The wikidata user interface makes it clear that there are two occurrences of the statement with different qualifiers, but how does the wikidata data model allows me to distinguish between these two occurrences? How do I know that: P580(start date) "March 4 1885" only applies to the first occurrence of the statement, while: P580(start date) "March 4 1893" only applies to the second occurrence of the statement? I could have a heuristic that says if two "start date"s are given, then assume that they are the starting points of two disjoint intervales. But can I always guarantee this?

ESWC 2014 Second Call for Workshops
by speroni＠cs.unibo.it 05 Nov '13

05 Nov '13

** apologies for cross-posting ** ==== Second Call for Workshops ==== http://2014.eswc-conferences.org/important-dates/call-workshops The organizers of the 11th ESWC 2014 cordially invite you to submit a workshop proposal. ESWC is a major venue for discussing the latest scientific results and innovations in the field of semantic technologies on the Web and Linked Data, attracting a high number of high quality submissions and participants from academia and industry alike. Co-located workshops at ESWC conferences are distinguished meeting points for discussing ongoing work and latest ideas related to semantic technologies and the Semantic Web. Of particular interest are workshop proposals with an interdisciplinary standpoint, proposals focusing on a specific technology of general interest, or gathering a sub-community. We encourage the submission of workshop proposals on: * Fundamental problems of the Semantic Web / Linked Data such as ontology mining, heterogeneity, scalability and distribution, uncertainty, etc. * Applications of Semantic Web technologies in specific domains, * Important enabling technologies and their adaptation to the needs of the Semantic Web, and * Aspects of Semantic Web research that have been neglected so far, * Techniques from other research fields that are of relevance for Semantic Web research (e.g., machine learning, NLP, data mining) # General Information and Criteria Each proposal will be reviewed by the members of the workshop programme committee, and ranked based on the overall quality of the proposal and the workshop's fit to the conference as detailed below. Their recommendation will determine the final decision on the acceptance/rejection of each proposal, which is to be taken by the workshop and tutorial chairs as well as by the local and the general chair of ESWC 2014. The criteria for judging the quality of workshop proposals are as follows: * Co-located workshops cover topics falling in the general scope of the ESWC conference. * Workshops are intended to be genuine interactive events and not mini-conferences. * We welcome workshops with creative structures and organizations that attract various types of contributions and ensure rich interactions. * Workshops should have a clear focus on a specific technology, problem or application. * There is potentially a significant community interested in the workshop's topic. * Workshop duration can be half a day or a full day. * We strongly advise having more than one organizer and no more than four, preferably from different institutions, bringing different perspectives to the workshop topic. In case overlapping workshops are proposed, the workshop chair may contact the organisers to discuss the possibility of merging workshops. Please note that the duration of a workshop might need to be adjusted based on the overall number of submissions received. Further, workshops that receive less than 5 submissions or have less than 10 people registered at the early registration deadline might be canceled. The organizers of accepted workshops will be responsible for their own reviewing process, publicity (e.g., website, timelines and call for papers), and proceedings production. They will be required to closely cooperate with the Workshop Chair and the ESWC 2014 local organizers to finalize all organizational details. Workshop attendees must pay the ESWC 2014 workshop registration fee, as well as the conference registration fee. Organizers of workshops and tutorials will get a free registration for workshops and tutorials at the pre-conference days, i.e. they will only have to pay the main conference fee. # Important Dates Workshop proposals due: Nov 22, 2013 - 23:59 Hawaii Time Notification of acceptance: Dec 6, 2013 - 23:59 Hawaii Time Workshop Web site due: Dec 16, 2013 - 23:59 Hawaii Time Workshop camera-ready proceedings due: Apr 25, 2014 - 23:59 Hawaii Time Workshop days: May 25 and May 26, 2014 # Suggested Timeline for Workshops Submission deadline: March 6, 2014 Notifications: April 1, 2014 Camera ready version: April 15, 2014 # Submission Guidelines Workshop proposals have to be submitted via Easychair. Each proposal must consist of a single PDF document written in English, not longer than 3 pages, which contains the following information: 1. The title and brief technical description of the workshop, specifying its goals and motivation. 2. A brief discussion of why the topic is of particular interest at this time. 3. A brief description of why and to whom the workshop is of interest, the workshop audience, as well as the expected number of participants. 4. A brief description (draft outline) of the proposed workshop format, discussing the mix of events and activities such as paper presentations, invited talks, panels, hacking session, or general discussion, and and an approximate timeline. 5. A list of (potential) members of the program committee (at least 50% have to be known and confirmed at the time of the proposal). 6. An indication of whether the workshop should be considered for a half-day or full-day event. 7. Related Workshops and Conferences: Is this the continuation of a workshop series or a new workshop to address an emerging issue? Please provide information about past versions of this workshop and other related workshops (including URLs and submission/acceptance counts, if available). 8. Names and contact information of the workshop organizers/chair(s) (name, affiliation, email address, homepage and short (one paragraph) biography of each chair, explaining the chair's expertise for the workshop including past experience in organizing/facilitating workshops). Preferably a single contact person per submission. The best papers of each workshop will be included in the supplementary proceedings of ESWC 2014, which will appear in the Springer LNCS series. # Workshop Chair Harald Sack (Hasso-Plattner Institute for IT Systems Engineering, DE) email: harald.sack(a)hpi.uni-potsdam.de # Programme Committee Abraham Bernstein (University of Zuerich, CH) Chris Bizer (University of Mannheim, DE) Jerome Euzenat (INRIA Grenoble Rhone-Alpes, FR) Dieter Fensel (University of Innsbruck, AT) Aldo Gangemi (CNR Institute of Cognitive Sciences and Technology, IT) Asuncion Gomez-Perez (Universidad Politecnica de Madrid, ES) Frank van Harmelen (VU University Amsterdam, NL) Manfred Hauswirth (DERI, National University of Ireland, Galway, IE) Pascal Hitzler (Kno.e.sis Center, Wright State University, Dayton, US) Enrico Motta (The Open University, Milton Keynes, UK) Rudi Studer (Karlsruhe Institute of Technology, DE)
