[Wikidata-l] Provenance tracking on the Web with NIF-URIs
by Sebastian Hellmann 23 Jun '12

23 Jun '12

Dear all, (Note: I could not find the document, where your requirements regarding the tracking of facts on the web are written, so I am giving a general introduction to NIF. Please send me a link to the document that specifies your need for tracing facts on the web, thanks) I would like to point your attention to the URIs used in the NLP Interchange Format (NIF). NIF-URIs are quite easy to use, understand and implement. NIF has a one-triple-per-annotation paradigm. The latest documentation can be found here: http://svn.aksw.org/papers/2012/WWW_NIF/public/string_ontology.pdf The basic idea is to use URIs with hash fragment ids to annotate or mark pages on the web: An example is the first occurrence of "Semantic Web" on http://www.w3.org/DesignIssues/LinkedData.html as highlighted here: http://pcai042.informatik.uni-leipzig.de/~swp12-9/vorprojekt/index.php?anno… Here is a NIF example for linking a part of the document to the DBpedia entry of the Semantic Web: <http://www.w3.org/DesignIssues/LinkedData.html#offset_717_729> a str:StringInContext ; sso:oen <http://dbpedia.org/resource/Semantic_Web> . We are currently preparing a new draft for the spec 2.0. The old one can be found here: http://nlp2rdf.org/nif-1-0/ There are several EU projects that intend to use NIF. Furthermore, it is easier for everybody, if we standardize a Web annotation format together. Please give feedback of your use cases. All the best, Sebastian -- Dipl. Inf.

[Wikidata-l] less hard-core version of the data model
by Lydia Pintscher 23 Jun '12

23 Jun '12

Heya folks :) We've published a version of the data model that is less technical and that should be easier to understand than the very detailed existing one. You can find it at http://meta.wikimedia.org/wiki/Wikidata/Notes/Data_model_primer Feedback welcome!

[Wikidata-l] reworked storyboard for linking Wikipedia articles
by Lydia Pintscher 22 Jun '12

22 Jun '12

Heya :) We reworked the storyboard we published a while ago for how we think linking between Wikipedia articles should work. They can be found here: http://meta.wikimedia.org/wiki/Wikidata/Development/Storyboard_for_linking_… Please have a look and give feedback. Also spread the word to others who are not on this list if you don't mind.

What relation does this have with the RDF model? Will this complex statement with qualifications, references and all that be a RDF molecule of some kind? Or will there be an extension of the RDF model to add reification, or something entirely different?

[Wikidata-l] Collaboration opportunity with MegaJoule.org
by Evan Sherwin 20 Jun '12

20 Jun '12

Dear Wikidata Team, My name is Evan Sherwin and I represent a California-based company called Lumina Decision Systems. We are developing a community-sourced information-sharing website, called MegaJoule.org, that specializes in structured numerical information about energy and energy technology. We are very interested in the Wikidata, and would like to discuss the possibility of collaboration. I am not totally sure who I was the right person to contact, so I hope it is OK that I am mailing this list. Much like Wikidata, MegaJoule.org is a community-sourced hub for structured information. The primary focus of MegaJoule.org is the collection and storage of numerical estimates of quantities like "the projected cost of installing residential solar panels in 2020," or "the current efficiency of utility-scale wind turbines." In addition to a numerical value and units, each estimate contains a wealth of metadata, including the source, technology and metric applicable, along with assumptions, uncertainty information, the year the estimate applies and more. Users create estimate, source, metric and technology records through a form-based interface, resulting in structured and highly searchable data. In addition, users can rate and discuss estimates, their sources, metrics, etc. We have also integrated a graphing tool that allows users to interact more meaningfully with the data in MegaJoule.org. From looking at the description of Wikidata, it seems like there are enough similarities between MegaJoule.org and Wikidata to allow for very fruitful collaboration in the field of energy, and perhaps even some direct data sharing. Would Wikidata be interested in collaborating with MegaJoule.org? Here is a link to our beta version: www.megajoule.org. I have also attached a document that describes the MegaJoule project in more detail. If you have any questions, please let us know. Sincerely, Evan Sherwin Associate Analyst, Lumina Decision Systems evan(a)lumina.com

[Wikidata-l] Wikidata Roundtable in Washington, DC
by Nicholas Michael Bashour 18 Jun '12

18 Jun '12

Dear all, Some of you may know, but some of you may not, that Wikimedia District of Columbia along with Sunlight Labs will be hosting a roundtable discussion on Wikidata and global open data this Thursday at the Sunlight Foundation offices in Washington, DC (see here: http://wikidataroundtable.eventbrite.com/). Katie Filbert, one of our Board of Directors members who's also on the development team for Wikidata, will be one of the speakers. If anyone on this list is in or near Washington, DC, please RSVP and join the discussion on Thursday. If not, please use this threat to discuss questions that you might want raised during the brainstorming session, or comments that you want to share with everyone there about Wikidata and its potential role in the global open data movement, etc. This discussion will not be focused solely on the technology or the development process of Wikidata, but also what features may make it useful to open data and other NGOs around the world, how to maximize its usefulness, how to ensure its success upon launch, and how to get the most people involved. We hope that following this event and before Wikimania, we will write a report with a set of suggestions and comments that we can deliver to the Wikidata team members who will be in attendance at Wikimania in July. Sincerely, Nicholas Michael Bashour President Wikimedia District of Columbia Washington, DC, USA

[Wikidata-l] Beyond phase 3: charts, table filtering and sorting etc.
by Jan Kučera 18 Jun '12

18 Jun '12

Hi there, it is probably to early to think about phase #3 (lists), but success of this phase will largely be in integrating the wikidata output into Wikipedia tables nicely. I think about various live tables with all sorts smart functions available, like column filtering, dynamic calculations (counting sums, average values etc.), charting etc. I know big part of this functionalities will be on Wikipedia side, but I fear there simply will not be wikidata integration enough in this was if your project does not take it into account... Has anyone been thinking about this issue? Kozuch

Von: Nadja Kutz <nadja(a)daytar.de> Datum: 14. Juni 2012 11:21:28 MESZ An: "Discussion list for the Wikidata project." <wikidata-l(a)lists.wikimedia.org> Betreff: Re:Re: [[meta:wikitopics]] updated Hello Evan Sherwin We just had a discussion in this thread (see http://article.gmane.org/gmane.org.wikimedia.wikidata/618) about companies who might be interested in a standartized way to represent meta-information. In fact since some while I am trying to make people think about the importance of a mathematical sound structuring and presentation of RDF standards for science and engineering applications, especially with respect to environmental issues, please see the article: http://www.azimuthproject.org/azimuth/show/Examples+of+semantic+web+applica… It might be interesting for you to hear that sofar the math and physics community did not react much on that - eventually this may be because it is a rather tedious, unrewarding work to implement such standards ? But there is in general and globally not so much support especially of mathematics, so it just may that it is right now a bit too much of a burden to the math community, next to the normal math tasks. And as you can see by our discussion in the thread the ISO seems to be equally hesitating. The above article is currently only located at the Azimuth project www.azimuthproject.org, which is a circle of mostly scientists who try to openly gather and structure environmental data. In the article there is also a description of a student project where visualization tools for RDF data where created. I had hoped that the students would put their software on sourceforge or so (and that I could announce this in the article about the semantic web applications), but they seem to be very busy these times, eventually they might even be now in internships at rather wellknown giant californian software industries :) The promotion of the article as a publication on the Azimuth project was sofar not so big. This may be because Azimuths public outreach program may not yet be overly advanced :). So my plan is currently to put the article on arxiv.org with the hope that some more mathematicians/scientists may get interested in these kind of tasks.
