[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

[Wikidata-l] Complete Datamodel in WON
by Jeroen De Dauw 18 Sep '12

18 Sep '12

Hey, I have some questions/remarks on the "Complete Datamodel in WON" section Markus wrote up yesterday: https://meta.wikimedia.org/wiki/Wikidata/Data_model#Complete_Datamodel_in_W… There are several things we have not modelled yet, which I'm currently not going to comment on. For those we did already implement or thought about implementing, there are a few things that do not match what's written in this section. > SiteLanguageCode All occurrences of this should be replaced by GlobalSiteIdentifier, as it's NOT a language code. > ItemDescription := 'ItemDescription(' Item {TitleRecord} [MultilingualTextValue] [MultilingualTextValue] {Statement} ')' This is missing the aliases stuff, which would be { UserLanguageCode String }. > GeoCoordinatesValue := 'GeoCoordinatesValue(' decimal decimal decimal ')' Altitude is probably something we will not have in many cases, so I think this ought to be optional. Another optional argument would be the globe to which the coordinates belong. Different globes have different ways of measuring coordinates, so a specific set of coordinates that is valid on one might mean something else on another and simply be invalid on a third. > PropertyDescription := 'PropertyDescription(' Property {TitleRecord} [MultilingualTextValue] [MultilingualTextValue] ')' Right now the Property interface is very similar to the Item one, except that Item has what we're calling sitelinks (in the here discussed WON it's called TitleRecords), and property does not. That's the first difference. Copy paste error? Or am I misinterpreting the notation? As with Item, it's missing the aliases. Although we have not implemented this yet, the Entity interface implies that it contains a list of statements. I added this after some discussion with Denny. As a result, both Items and Properties have a list of statements. That's the third difference with the WON stuff. Here the question is if non-Item Entities should have statements or not. There is no consensus on this within the team yet, so I will start a new thread about it so we can discuss it in more detail. Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic.

[Wikidata-l] Entities, statements and claims
by Jeroen De Dauw 17 Sep '12

17 Sep '12

Hey, There is some disagreement regarding the interface to access statements in various entities. == Current implementation == This is not fully implemented yet, but it's what the interface implies will be done. Entities contain a list of statements. In other words, all items, properties and queries can have statements. Obvious objection: "statements" for properties and queries should not have associated rank and references. They could just have a list of claims. Original reason to go with this approach anyway: the alternative is to put statement handling in Item and add claim handling in either both Property and Query or in a common base. This would result in duplication and loss of common interface for the Entities. == New proposal == I think we can accommodate all the concerns listed above as follows: * All Entities provide access to a list of claims. * Properties and Queries contain a list of claims. * Items contain a list of statements to which they provide access both as list of statements and list of claims. The apparent list of claims would correspond to a filter on rank=primary followed by a map from statement to it's claim on the list of statements. Any objections to implementing it like that? Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic. Don't be evil. --

[Wikidata-l] Schema.org markup in Wikidata concepts.
by Klein,Max 15 Sep '12

15 Sep '12

Hello all, I was wondering, now that Wikidata breaks the assumption that pages store wikitext, has it been considered that Wikidata concept pages could actually use schema.org markup? Wikidata could possibly read in data from other web pages which use schema.org markup, but what about the Wikidata pages themselves having the markup?

[Wikidata-l] CFP 10th ESWC 2013 - Semantics and Big Data - Montpellier, France.
by Cord Wiljes 14 Sep '12

14 Sep '12

10th ESWC 2013 -- Semantics and Big Data May 26-30, 2013, Montpellier, France. http://2013.eswc-conferences.org/ General Chair: Philipp Cimiano (Bielefeld University, DE) Program Chairs Valentina Presutti (STLab, ISTC-CNR, IT) Oscar Corcho (UPM, ES) ==== *Call for Papers* ==== ESWC is the premier European-based annual conference for researchers and practitioners in the field of semantic technologies. ESWC is the ideal venue for the discussion of the latest scientific insights and novel applications of semantic technologies. The leading motto of the 10th edition of ESWC will be "Semantics and Big Data". A crucial challenge that will guide the efforts of many scientific communities in the years to come is the one of making sense of large volumes of heterogeneous and complex data. Application-relevant data often has to be processed in real time and originates from diverse sources such as Linked Data, text and speech, images, videos and sensors, communities and social networks, etc. ESWC, with its focus on semantics, can offer an important contribution to global challenge. ESWC 2013 will feature nine thematic research tracks (see below) as well as an in-use and industrial track. In line with the motto "Semantics and Big Data", the conference will feature a special track on "Semantic Technologies for Big Data Analytics in Real Time". In order to foster the interaction with other disciplines, this year's edition will also feature a special track on "Cognition and Semantic Web". For the research and special tracks, we welcome the submission of papers describing theoretical, analytical, methodological, empirical, and application research on semantic technologies. For the In-Use and Industrial track we solicit the submission of papers describing the practical exploitation of semantic technologies in different domains and sectors. Submitted papers should describe original work, present significant results, and provide rigorous, principled, and repeatable evaluation. We strongly encourage and appreciate the submission of papers including links to data sets and other material used for the evaluation as well as to live demos or source code for tool implementations. Submitted papers will be judged based on originality, awareness of related work, potential impact on the Semantic Web field, technical soundness of the proposed methods, and readability. Each paper will be reviewed by at least three program committee members in addition to one track chair. This year a rebuttal phase has been introduced in order to give authors the opportunity to provide feedback to reviewers' questions. The authors' answers will support reviewers and track chairs in their discussion and in taking final decisions regarding acceptance. ** Important Dates (11:59pm Hawaii Time) ** Abstract submission: December 5th, 2012 Full paper submission: December 12th, 2012 Authors' rebuttals: February 11th-12th, 2013 Acceptance Notification: February 22nd, 2013 Camera ready: March 9th, 2013 Conference: May 26th-30th, 2013 ** Submission information ** All papers and abstracts have to be submitted via the conference submission page:https://www.easychair.org/conferences/?conf=eswc2013 Each submitted paper must be associated with one of the available tracks. Abstract submission is a strict requirement. Papers will be published by Springer in the Lecture Notes in Computer Science (LNCS) series. Papers must be in English, should not exceed fifteen (15) pages in length and must be formatted according to the LNCS guidelines. More information about Springer's LNCS series are available on the Springer LNCS Web site. Papers must be submitted in PDF (Adobe's Portable Document Format) format and will not be accepted in any other format. Papers that exceed 15 pages or do not follow the LNCS guidelines can be rejected automatically without a review. Authors of accepted papers will be required to provide semantic annotations for the abstract of their submission at the time of acceptance. At least one author of each accepted paper must register for the conference and present the paper there. All tracks and associated chairs are listed below.
