[Wikidata-l] Old properties are now invalid
by Jeroen De Dauw 02 Oct '12

02 Oct '12

Hey, The DataType code that recently got merged into Wikibase now enforces properties to have a DataType. Calling getProperty or toArray on a Property without a DataType will get your an exception. This means that if you created properties before the new code got introduced they will now be invalid. Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic. Don't be evil. --

[Wikidata-l] comparison articles
by Amir E. Aharoni 30 Sep '12

30 Sep '12

Hi, Geekiness warning: this email mentions software in general and free software licenses in particular. It mentions them because it's a useful example, but the ideas can be applied to many other domains. Automatic generation of list articles is frequently named as one of the main use cases of Wikidata. There is, however, a particular type of list articles for which Wikidata may be even more useful: Comparison articles. You can find many examples of these at Category:Software comparisons in the English Wikipedia. It can be used for comparing cars, athletes, political candidates and many other things. I frequently use such articles to help myself choose software that I will use. Here's what I do today to search for software, and what I would love to see supported better using Wikidata: * I always prefer to try Free Software first. Today I usually go to such an article, sort the table by the license column, and then start comparing features that are important to me. * Very often the different groups of features appear in different tables, so I have to scroll up and down a lot. * Very often I quickly narrow down my search to a small number of products, but there's no easy way to remove the products that I decided not to use from the view, so again I have to scroll up and down a lot. Doing the above using a query would be very useful. I would be able to quickly eliminate rows (products) and columns (features) that don't interest me. -- Amir Elisha Aharoni · אָמִיר אֱלִישָׁע אַהֲרוֹנִי http://aharoni.wordpress.com ‪“We're living in pieces, I want to live in peace.” – T.

by Lydia Pintscher 27 Sep '12

27 Sep '12

Heya folks :) We've updated the demo system again. We're getting into phase 2 territory now but that's not very visible yet. What you can give a try however is that changes on the repository should now show up in the recent changes of the client. The git tag is fb4f3e9af2e43b0035b05fcf8ad88c887bfc95d8. http://wikidata-test.wikimedia.de Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Community Communications for Wikidata Wikimedia Deutschland e.V.

[Wikidata-l] Call for Workshops - 10th ESWC 2013 - Semantics and Big Data - May 26-30, 2013 - Montpellier, France.
by Cord Wiljes 20 Sep '12

20 Sep '12

10th ESWC 2013 -- Semantics and Big Data May 26-30, 2013. Montpellier, France. http://2013.eswc-conferences.org/ ==== Call for Workshops ==== The organizers the 10th ESWC 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 Web technologies. Co-located workshops at ESWC conferences are distinguished meeting points for discussing ongoing work and latest ideas related to semantics 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 such as heterogeneity, scalability and distribution, - 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. *** 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 2013. 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 (refer to http://www.eswc-conferences.org). - 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. - They are clearly focused. - There is potentially a significant community interested in the workshop's topic. - Workshop duration can be half a day or a full day. - We 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 and call for papers), and proceedings production. They will be required to closely cooperate with the Workshop Chair and the ESWC 2013 local organizers to finalize all organizational details. Workshop attendees must pay the ESWC 2013 workshop registration fee, as well as the conference registration fee. Organizers of workshops and tutorials will get a free registration for workshop and tutorials, i.e. they will only have to pay the main conference fees. Further, each workshop or tutorial that attracts more than 15 registered participants (excluding the organizers) will get one full registration for the conference. This registration can be used for example to pay for an invited speaker. *** Submission Guidelines *** Workshop proposals have to be submitted via Easychair (https://www.easychair.org/conferences/?conf=eswc2013workshops). Each proposal must consist of a single PDF document, 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 such as paper presentations, invited talks, panels, hacking session, or general discussion. 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. If there have been previous editions of the workshop, their short description, including URLs as well as some statistics about submissions and acceptance rate, plus number of participants. 8. The names and contact information (web page, email address) of the proposed organizing committee and short description of their relevant experience. Preferably a single contact person per submission. The best papers of each workshop will be included in the supplementary proceedings of ESWC 2013, which will appear in the Springer LNCS series. *** Workshop Chair *** Johanna Völker (University of Mannheim, DE) voelker(a)informatik.uni-mannheim.de *** Programme Committee *** Chris Bizer (University of Mannheim, DE) Dieter Fensel (University of Innsbruck, AT) Aldo Gangemi (CNR Institute of Cognitive Sciences and Technology, IT) Asuncion Gomez-Perez (Universidad Politécnica de Madrid, ES) Frank van Harmelen (VU University Amsterdam, NL) Pascal Hitzler (Kno.e.sis Center, Wright State University, Dayton, US) Enrico Motta (The Open University, Milton Keynes, UK) *** Important Dates *** Workshop proposals due: Nov 23, 2012 - 23:59 Hawaii Time Notification of acceptance: Dec 7, 2012 - 23:59 Hawaii Time Workshop Web site due: Dec 17, 2012 - 23:59 Hawaii Time Workshop camera-ready proceedings due: Apr 29, 2013 - 23:59 Hawaii Time Workshop days: May 26 and May 27, 2013 *** Suggested Timeline for Workshops *** Submission deadline: March 4, 2013 Notifications: April 1, 2013 Camera ready version: April 15, 2013

10th ESWC 2013 -- Semantics and Big Data May 26-30, 2013. Montpellier, France. http://2013.eswc-conferences.org/ ==== Call for Tutorials ==== ESWC 2013 invites tutorials that address the interests of its varied audience: people new to the Semantic Web, Semantic Web researchers and practitioners that wish to learn new technologies, users of Semantic Web technologies, and representatives of government and funding agencies as well as potential private investors in Semantic Web technologies. We welcome submissions of tutorial proposals on all major topics related to semantic technologies. We especially solicit proposals for tutorials of the following types: - Tutorials with a coherent theme providing an introduction to new semantic technologies and trends. - Tutorials describing the application of semantic technologies in specific domains (e.g., life-sciences, e-government, e-commerce etc.). - Tutorials presenting techniques from other research fields that are of relevance for Semantic Web research especially in relationship to the tracks of the conference (e.g., techniques from social science, database techniques, NLP techniques etc.). Tutorials can be half a day or a full day. We advise having more than one presenter and no more than three, preferably from different institutions, bringing different perspectives to the workshop topic. Tutorials may focus entirely on theoretical aspects; however, we encourage organisers to incorporate hands-on sessions where appropriate. The tutorials should reach a good balance between the topic coverage and its relevance to the community. Timeline for Tutorials ---------------------- Proposals due: Nov 23, 2012 - 23:59 Hawaii Time Notification of acceptance: Dec 7, 2012 - 23:59 Hawaii Time Tutorial Web site due: Dec 17, 2012 - 23:59 Hawaii Time Camera-ready material due: Apr 29, 2013 - 23:59 Hawaii Time Tutorial days: May 26 and May 27, 2013 Responsibilities ---------------- Organizers of accepted tutorials are responsible for preparing and maintaining a Web site that describes the tutorial and includes all relevant information.
