[Wikidata-l] Dexbot problem
by Andy Mabbett 02 Oct '13

02 Oct '13

There's a problem with Dexbot adding bogus values. For example, place of death = "Welsh People" on the entry for Catrin Collier (still very much alive): http://www.wikidata.org/w/index.php?title=Q13416998&diff=72279065&oldid=497… Since I have no broadband, due to an ISP failure, I can't post about this on-Wiki. -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk

[Wikidata-l] ESWC 2014 Call for Tutorials
by essepuntato＠cs.unibo.it 01 Oct '13

01 Oct '13

** apologies for cross-posting ** ==== Call for Tutorials ==== http://2014.eswc-conferences.org/important-dates/call-tutorials ESWC 2014 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, cultural heritage, 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 tutorial 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 22, 2013 - 23:59 Hawaii Time Notification of acceptance: Dec 6, 2013 - 23:59 Hawaii Time Tutorial Web site due: Dec 16, 2013 - 23:59 Hawaii Time Camera-ready material due: Apr 25, 2014 - 23:59 Hawaii Time Tutorial days: May 25 and May 26, 2014 Responsibilities ----------- Organizers of accepted tutorials are responsible for preparing and maintaining a Web site that describes the tutorial and includes all relevant information. Organizers are also responsible for submitting the material for attendees (slide sets, additional teaching material, software installation and usage guides for practical hands-on sessions, etc.) to the Tutorial Chair. The ESWC 2014 Organizing Committee is responsible for providing publicity for the tutorials as part of the conference publicity activities, and on-site logistical support to the organizers and attendees. Tutorial attendees must pay the ESWC 2014 workshop registration fee, as well as the conference registration fee. General Information ----------- Each tutorial will have one reduced registration fee (pre-conference days registration will be free i.e. one of the chairs will only have to pay the main conference fees). In the interest of the overall quality of the conference, the Tutorial Chair reserves the right to merge tutorials and/or adjust the scope thereof in case a mimimum number of registrations is not reached by the early registration deadline. Submission details ----------- Tutorial proposals should not exceed 5 pages, using an 11 pt font for the body of the text of the proposal and should contain the following information: - Abstract (200 words maximum, for inclusion on the ESWC 2014 website). - Tutorial description: More specifically, it should specify the objectives of the tutorial and relevance to ESWC 2014, include enough details on the scope of the material to be covered and the depth to which it will be covered and specify the intended audience and any prerequisite knowledge. Appropriate references to the material to be covered by the tutorial must be included. - Tutorial length. The tutorial can be full or half day (if the tutorial can be either length, please be sure to identify which material is included for each length). - Specify other venues to which the tutorial or part thereof has or will be presented, in addition to explaining how the current tutorial differs from the other editions. Links to the slides of those tutorial editions should be included in the proposal. - Brief professional biography of the presenter(s) indicating previous training and speaking experience (such as teaching and tutorial presentation). Each proposal will be reviewed by the members of the tutorial programme committee, and ranked based on the overall quality of the proposal and the tutorial's fit to the conference. Their recommendation will determine the final decision on the acceptance/rejection of each proposal. Submission ----------- Submission will be through the Easychair system (please note that it is the same site to submit workshops and tutorials) https://www.easychair.org/conferences/?conf=eswc2014workshops-tutorials Tutorials Chair Nathalie Aussenac-Gilles (IRIT-CNRS, Toulouse, Fr) email: aussenac(a)irit.fr

[Wikidata-l] ESWC 2014 Call for Workshops
by essepuntato＠cs.unibo.it 01 Oct '13

01 Oct '13

** apologies for cross-posting ** ==== 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: The title and brief technical description of the workshop, specifying its goals and motivation. A brief discussion of why the topic is of particular interest at this time. A brief description of why and to whom the workshop is of interest, the workshop audience, as well as the expected number of participants. 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. A list of (potential) members of the program committee (at least 50% have to be known and confirmed at the time of the proposal). An indication of whether the workshop should be considered for a half-day or full-day event. 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). 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).

[Wikidata-l] Wikidata Toolkit: call for feedback/support
by Markus Krötzsch 01 Oct '13

01 Oct '13

Dear Wikidatanions (*), I have just drafted a little proposal for creating more tools for external people to work with Wikidata, especially to build services on top of its data [1]. Your feedback and support is needed. Idea: Currently, this is quite hard for people, since we only have WDA for reading/analysing dumps [2] and Wikidata Query as a single web service to ask queries [3]. We should have more support for programmers who want to load, query, analyse, and otherwise use the data. The proposal is to start such a toolkit to enable more work with the data. The plan is to kickstart this project with a small team using Wikimedia's Individual Engagement program. For this we will need your support -- feel free to add your voice to the wiki page [1]. Of course, comments of all sorts are also great -- this email thread will be linked from the page. If you would like to be involved with the project, that's great too; let me know and I can add you to the proposal. The proposal will already be submitted tomorrow, but support should also be possible after that, I hope. Cheers, Markus (*) Do we have a demonym yet? Wikipedian sounds natural, Wikidatan less so. Maybe this should be another thread ... ;-) [1] https://meta.wikimedia.org/wiki/Grants:IEG/Wikidata_Toolkit [2] http://github.com/mkroetzsch/wda [3] http://208.80.153.172/wdq/ -- Markus Kroetzsch, Departmental Lecturer Department of Computer Science, University of Oxford Room 306, Parks Road, OX1 3QD Oxford, United Kingdom +44 (0)1865 283529 http://korrekt.org/

[Wikidata-l] WpIAF and WdIAF?
by John Erling Blad 30 Sep '13

30 Sep '13

It seems like some GLAM institutions are starting to use URLs to Wikipedia articles as common identifiers for classes of items in collections. I guess this will change over time to be URLs to Wikidata instead. This is pretty much as expected, but it is although a bit strange that they are using Wikipedia and that no-one seems to have noticed this from our side. Is there anyone that know how common this is? Så far I have only heard about a few of them, and I'm not even sure they have any clear understanding why they do it.. John / jeblad

I know of a couple of Swedish museums/institutions which do it. Either manually or bed on which pages/images contains links pointing back to specific items in their collections. Essentially they use it as a "you might also be interested in" suggestion. Also know that a few of their authority files includes wikipedia links as "same_as" properties. /André ------ André Costa GLAM-tekniker Wikimedia Sverige Den 27 sep 2013 08:43 skrev "John Erling Blad" <jeblad(a)gmail.com>: It seems like some GLAM institutions are starting to use URLs to Wikipedia articles as common identifiers for classes of items in collections.

Re: [Wikidata-l] Cooperation between Wikidata and DBpedia and Wikipedia
by Christian Bizer 25 Sep '13

Hi Gerard and all, Von: Gerard Meijssen [mailto:gerard.meijssen@gmail.com] Gesendet: Mittwoch, 25. September 2013 10:26 An: Kingsley Idehen Cc: Discussion list for the Wikidata project.; Chris Bizer; Samuel Klein; Sören Auer; Christian Bizer Betreff: Re: [Wikidata-l] Cooperation between Wikidata and DBpedia and Wikipedia Hoi, Congratulations on the new version of DBpedia :) .. This makes it an auspicious occasion to talk about future collaboration. At this time several Wikimedians are busy harvesting data from Wikipedia and loading it into Wikidata. Yes, we did see this and of course all these Wikimedians are more than welcome to reuse parts of our code for building their harvesters (the DBpedia extraction framework does a lot of little things around data cleaning and recognizing different variations of values as well as normalizing units of measurements that I guess would also be useful for the other harvesters.) You are harvesting data from Wikipedia and loading it into DBpedia. As we are including data into Wikidata, it goes into DBpedia as well... We might as well work together on this. One of the best parts (as far as I am concerned) is your knowledge of fields used in infoboxes and knowing how they are the same / related to fields in other infoboxes. This expertise should be easy to absorb into Wikidata Yes, all the information about the infobox to ontology mappings are maintained by the DBpedia community in the mappings wiki (http://mappings.dbpedia.org/index.php/Main_Page) and of course Wikidata is more than welcome to use them. As far as I know the mappings wiki also already contains mappings from DBpedia classes/properties to the corresponding Wikidata classes/properties for about 1/3 of all classes/properties (Sebastian Hellmann cc’ed knows more about this). So it would be very simple for you to use the mappings to fill your repository. In Wikidata we use qualifiers, will you adopt qualifiers in DBpedia? At this time qualifiers are not handled by the harvesting software I am familiar with. What kind of qualifiers? Do you mean provenance information? To me these are the two issues that determine how easy it will be to effectively collaborate on great content for Wikidata. To me the most important aspect of Wikidata is that it is actually used. Information added becomes available in many places. Consequently more data for Wikidata, data that fits in well and is closely related to the 100+ wikipedias you are harvesting will ensure a rich experience in so many places. Yes.

Re: [Wikidata-l] Cooperation between Wikidata and DBpedia and Wikipedia
by Gerard Meijssen 25 Sep '13

Hoi, I have been blogging a lot the last two days with DBpedia in mind. My understanding is that at DBpedia a lot of effort went into making something of a cohesive model of properties. Now that the "main type GND" is about to be deleted, it makes sense to adopt much of the work that has been done at DBpedia. The benefits are: - we will get access to academically reviewed data structures - we do not have to wait and ponder and get in to thebusiness enriching the data content of DBpedia - we can easily compare the data in DBpedia and Wikidata - more importantly, DBpedia has spend effort in connecting to other resources Yes, we can import data from DBpedia and we can import data from Wikipedia. Actually we can do both. The one thing that needs to be considered is that we need data before we can curate it. With more data available it becomes more relevant to invest time in tools that compare data. We can start doing this now and, over time this will become more relevant. But now we need more properties and the associated date. What do you think? Thanks, GerardM http://ultimategerard.blogspot.com
