[Wikidata-l] Fwd: [Wikitech-l] Deployment of Wikidata
by Lydia Pintscher 06 Aug '12

06 Aug '12

Heya folks This hasn't made it to this list yet sorry. The Hungarian Wikipedia community has stepped up to be the first one to use Wikidata in production once we're ready to deploy the code. They rock :D We're keeping track of the deployment plans here: http://meta.wikimedia.org/wiki/Wikidata/Notes/Deployment Cheers Lydia ---------- Forwarded message ---------- From: Bináris <wikiposta(a)gmail.com> Date: Tue, Jul 24, 2012 at 1:52 PM Subject: Re: [Wikitech-l] Deployment of Wikidata To: Wikimedia developers <wikitech-l(a)lists.wikimedia.org> 2012/7/14 Lydia Pintscher <lydia.pintscher(a)wikimedia.de> > > Just to keep everyone updated: We have discussed this here at > Wikimania together with a few of the admins of the Hungarian > Wikipedia.

(22 of them in the first 24 hours.) As I wrote earlier, this is an enthusiastic community. So huwiki is looking forward to test Wikidata. :-) Let's do it! -- Bináris _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l -- Lydia Pintscher - http://about.me/lydia.pintscher Community Communications for Wikidata Wikimedia Deutschland e.V.

[Wikidata-l] Wikidata links
by Gregor Hagedorn 03 Aug '12

03 Aug '12

On https://meta.wikimedia.org/wiki/Wikidata/Notes/URI_scheme#Proposal_for_Wiki… I am missing the arguments why Wikidata needs the multitude of URI forms. The list needs commenting and arguments why "URIs should be canonical within Wikimedia projects" is given up. ---- (Of lesser importance, I wonder why the internal opaque ID has to be prefixed by a letter (Q) - why not a simple number?) ---- At them moment I believe a choice should be made between: http://{site}.wikidata.org/wiki/{title} and http://wikidata.org/title/{site}:{title} but perhaps the argument why both are needed could be added. ---- On the issue of interlanguage/interwiki linking, I believe the semantics should not be opposite in Wikidata and Wikipedias, see my comment https://meta.wikimedia.org/wiki/Talk:Wikidata/Notes/Wiki_links Gregor

[Wikidata-l] on-wiki newsletter
by Lydia Pintscher 01 Aug '12

01 Aug '12

Heya folks :) One of the suggestions that came up at Wikimania was to have a newsletter for Wikidata. The idea is that people can sign up and then have important stuff posted to their user talk pages by a bot. Is anyone able to help me set this up?

[Wikidata-l] New client storyboards
by Katie Filbert 31 Jul '12

31 Jul '12

We have created an updated set of storyboards for adding and editing interlanguage wiki links on Wikipedia. These incorporate feedback we've gotten and are an attempt to simplify the process. I'm sure there are some further changes that could be done to improve it, especially in the scenario where a Wikipedia page includes interlanguage wiki links from both Wikidata and from the local wikitext. http://meta.wikimedia.org/wiki/Wikidata/Development/Storyboard_for_linking_… Please provide feedback. Cheers, Katie -- Katie Filbert Wikidata Developer Wikimedia Germany e.V. | NEW: Obentrautstr. 72 | 10963 Berlin Phone (030) 219 158 26-0 http://wikimedia.de Wikimedia Germany - Society for the Promotion of free knowledge eV Entered in the register of Amtsgericht Berlin-Charlottenburg under the number 23 855 as recognized as charitable by the Inland Revenue for corporations I Berlin, tax number 27/681/51985.

[Wikidata-l] ANN: Multilingual Linked Open Data for Enterprise (MLODE) Leipzig, September 23-24-25, 2012
by Sebastian Hellmann 24 Jul '12

24 Jul '12

*Save the date: Leipzig, Germany 23-24-25 September 2012 http://sabre2012.infai.org/mlode Co-located with the Leipziger Semantic Web Day: http://aksw.org/lswt ====== Multilingual Linked Open Data for Enterprises ====== MLODE will bring together developers, data producers, academia and enterprises and connect people, communities, data and industrial use cases. The workshop will be very interactive and you are expected to help us achieve common goals: * bootstrap and build a Linguistic Linked Open Data Cloud (LLOD): http://linguistics.okfn.org/resources/llod/ * establish best practices for multilingual linked open data * create incentives for businesses and lower the barrier for participation in LOD for natural language processing and internationalisation and localisation enterprises. We are expecting intensive participation by members of the following communities (these are teasers, see the **detailed descriptions for each community** further below): * DBpedia ( http://dbpedia.org <about:blank>): DBpedia International now has over 10 language-specific chapters (such as http://el.dbpedia.org <http://el.dbpedia.org/>). At the MLODE workshop there will be a DBpedia Developers meetup. We will discuss the "Future of DBpedia" and create a common Road Map. If you want to get more involved in DBpedia, the workshop will be a good opportunity to meet the team. * Working Group for Open Data in Linguistics (OWLG, http://linguistics.okfn.org <http://linguistics.okfn.org/%29> ): Now is the time to get your data into the LLOD cloud! We have created a development team that will convert your data to RDF and help establish links: http://code.google.com/p/mlode/. Please submit your data sets soon! (Furthermore we will have a legal session to discuss licensing issues.) * Multilingual Web ( http://www.multilingualweb.eu <http://www.multilingualweb.eu/>): Free, open data and lexica; we will have a session discussing best practices for multilingual linked open data (http://mlode.okfnpad.org/best-practices-multilingual-lod) and compatability with the RDF world with ITS 2.0. * Apache Stanbol ( http://incubator.apache.org/stanbol/): Enterprises will have the chance to present their use cases during lightning talks and we will have a Apache Stanbol Booth and an install fest to show hands-on how combined usage of public and closed data can be achieved and what benefits firms can gain from using these rapidly increasing data pools. * Ontolex W3C Community Group ( http://www.w3.org/community/ontolex/): Monnet Challenge will provide a data bounty for developers who convert data sets using lemon. * Also: NLP2RDF (http://nlp2rdf.org <http://nlp2rdf.org/>) - the NIF project, DBpedia Spotlight (http://spotlight.dbpedia.org <http://spotlight.dbpedia.org/>), Wiktionary2RDF (http://dbpedia.org/Wiktionary) How you can contribute: * Contact us if you are an enterprise and want to prepare a small presentation/lightning talk about your business use cases (using LOD) or problems you have (please see below for details) * Contact us if you want to give a short presentation on a relevant topic * We are looking for a sponsor for a DBpedia Booth * Submit your data sets for the LLOD: http://code.google.com/p/mlode/ * Become a sponsor of the workshop: http://sabre2012.infai.org/mlode/funding?&#sponsorship * Or donate money and help the individual communities: http://sabre2012.infai.org/mlode/Funding DBpedia is a good example of a freely available and open data set that was generated by crowd-sourcing and academia, but it has provided an immense value to businesses and industry. We want to build on and continue this success for the areas of natural language processing enterprises and the internationalisation and localisation industries. The goal of the workshop is to bootstrap a Multilingual Linked Open Data cloud by bringing together many different linked open data sets and by creating synergy among different research and business communities. This workshop is aimed at researchers and industry and commercial consumers of data produced by research. We hope for mutual benefits between (potentially non-commercial) data providers and enterprises: Open-source and open-licences for software have shown that they can be successful in a commercial environment. How can we transfer these models to Multilingual Linked Open Data? And how can the transformation of currently monolingual Linked Open Data sources into a Multilingual Web of Open Data spur cross-linguistic research, and commercial applications in internationalisation and localisation enterprises? ===== Sponsors ===== We would like to thank our sponsors for supporting the workshop: * The **Working MultilingualWeb-LT Working Group** - http://www.w3.org/International/multilingualweb/lt/ * The **Interactive Knowledge Stack (IKS) EU Research Project** - http://www.iks-project.eu/ * The **Monnet Project** - http://www.monnet-project.eu/ ===== Monnet Challenge ===== The Monnet Project (http://www.monnet-project.eu/) is offering the following bounties for the conversion of existing linguistic resources into linked data, in particular focussing on the **lemon format** (http://www.monnet-project.eu/lemon) . **Bounties are 600, 400, 200, 100, 50 Euros** . The selection of winners will be done by a committee of Ontolex community members. Core criteria: * Number of triples (relative to other submissions). Emphasis is of course on number of triples containing a URI from //lemon// . * Expressiveness and quality of lemon used (How many properties and classes of //lemon// are you using? Are you using them correctly?) * Impact (Is the data set you converted important and central to our cause? We also rate data sets for less-spoken languages higher, because of the rarity effect.) Additional criteria: * Note that you can convert and submit more than one data set. You will be rated for the combined data you converted (so each person can only make one submission). * You will be given extra points if you publish converted data early and other people build upon your work (e.g. fix errors). * All submissions will be considered for inclusion in the data post-proceedings. Detailed information on how to submit can be found on the Monnet Challenge page: http://sabre2012.infai.org/mlode/monnet-challenge Submission will end 10 days before the workshop. The deadline therefore is **September 13th, 2012** ===== Planned Sessions ===== Each session will have an etherpad http://sabre2012.infai.org/mlode/etherpadso that you can already participate in advance. ==== Submit your data today ==== In preparation, from now until September 23rd, we will: * Collect data sets relevant to the Linguistic Linked Open Data Cloud http://code.google.com/p/mlode/ * Provide conversion services and data 'bounties' to convert as much data as possible to RDF before the workshop * Help debugging and hosting your Linked Data We are interested in data that is linguistic in nature, such as corpora and lexica, as well as data that might be used to improve Natural Language Processing methods such as large governmental parallel corpora or entity linking engines. ==== Sun 23th: Community Get Together ==== Community Get Together - no program, just social activities, e.g. barbecue, beach volleyball. Time and place will be announced soon. ==== 24th: Code-Sprint-a-Thon ==== Code-Sprint-a-Thon (hands-on workshop) with data providers, visionaries and developers from all communities. The focus of the Code-Sprint-a-Thon will be on gathering the requirements and use cases from attendees and then developers will start to initiate these ideas with the collected data sets, e.g. interesting cross-data set queries, visualisations, data mash-ups. The result will be more Multilingual Linked Open Data, more links, more tools and more applications. === DBpedia === Many DBpedia developers will be available during this workshop so that you can ask them questions directly. Bring your laptop and they will show you how to download and query DBpedia. === Apache Stanbol === Developers from Apache Stanbol ( http://incubator.apache.org/stanbol/) will be at the Apache Stanbol booth and they will have an install fest to show hands-on how combined usage of public and closed data can be achieved and what benefits firms can gain from using the rapidly increasing data pools. ==== 25th: Announcements ==== * State of the Linguistic LOD Cloud ( http://linguistics.okfn.org/resources/llod/) * NIF 2.0 (http://wiki.nlp2rdf.org/) * Presentation of the results of the Code-Sprint-a-Thon * Announcement of the Monnet Challenge Winners ====25th: Lightning Talks: Use Cases by Enterprises ==== We are looking for companies to present their use cases and/or products that are relevant to the topics of the MLODE workshop. Please contact us if your enterprise would like to present on a topic from this (non-exhaustive) list: * Use cases based on Linked Data (either open or closed) * Solutions that are built with data from the LOD cloud * Problems that constitute barriers for economic exploitation of LOD * Ideas of what could be built with Linguistic/Multilingual LOD We aim to address questions like: * How can we unlock the data created by research and open communities for enterprises? * What is missing? * How can we build bridges? Submission ends on September 13th, which is one week before the workshop. Presentations will be around 3-5 minutes. ====25th: Session on Best Practices for Multilingual Linked Open Data ==== Please have a look at the etherpad: http://mlode.okfnpad.org/best-practices-multilingual-lod <http://mlode.okfnpad.org/best-practices-multilingual-lod?> <http://mlode.okfnpad.org/best-practices-multilingual-lod?> ====25th: Session on Legal Issues ==== Erik Ketzan (http://www.linkedin.com/in/erikketzan) <http://www.linkedin.com/in/erikketzan%29>will present the Clarin Legal Helpdesk and talk about current problems regarding database licences. Please have a look at the etherpad: http://mlode.okfnpad.org/legal-session ==== 25th: Session on DBpedia Roadmap ==== Please have a look at the etherpad: http://mlode.okfnpad.org/DBpedia-roadmap ==== Data post proceedings ==== This workshop will publish a data post proceedings. As this is a new concept, the rules for submission are not yet fixed. We will collect ideas here: http://mlode.okfnpad.org/data-post-proceedings During the discussion at the conference, we will pin down the details. ===== Participating Communities ===== ==== Multilingual Web ==== MLODE Contact: Dominic Jones ( https://www.scss.tcd.ie/dominic.jones/) Many ideas were generated into the best-practice use of Multilingual LOD at the W3C sponsored "Multilingual Web -- Linked Open Data and MultilingualWeb-LT Requirements" workshop held in Dublin, Ireland, June 2012 (http://www.multilingualweb.eu/en/documents/dublin-workshop/dublin-program). One of the aims of MLODE workshop is to continue discussion around the best-practices for application of LOD in the Multilingual Web and the transformation of currently monolingual LOD resources into multiple languages, for example a multi-lingual DBpedia. Topics for discussion and talking points will be carried over from the Dublin workshop and discussed during the MLODE workshop but new ideas or suggestions are of course welcome and requested. We will have a session discussing best practices for multilingual linked open data and compatibility of the RDF world with ITS 2.0. You can already participate in the discussion: http://mlode.okfnpad.org/best-practices-multilingual-lod ==== DBpedia ==== MLODE Contact: Dimitris Kontokostas DBpedia ( http://dbpedia.org <about:blank>): DBpedia International now has over 10 language-specific chapters (such as http://el.dbpedia.org <http://el.dbpedia.org/>) .

[Wikidata-l] chembox and drugbox
by dr.cueppers.gmbh＠arcor.de 24 Jul '12

24 Jul '12

To the question from Vishnu Mohan: I would like to know what will happen to chembox and drugbox? I think this is a wrong question: wikidata don't store complete chemboxes or drugboxes, but only each parameter, that will be used in this boxes (like "smelting point" etc.). So each Wikipedia will have or can have different boxes - but for a given substance all Wikipedias will show the same smelting point. dr.cueppers (redaction for chemistry in German-WP) Dr. Cüppers GmbH Hübnerstraße 2 33104 Paderborn 05254 935700
