[Wikidata-l] Hello from the YAGO team
by Fabian M. Suchanek 14 Apr '12

14 Apr '12

Dear Wikidata team, I am writing on behalf of the YAGO team at the Max Planck Institute for Informatics in Saarbruecken [1]. We have heard about the Wikidata project, and we are very excited to learn that you aim to launch a free knowledge base in the spirit of Wikipedia. We would like to get in touch with you -- also to see whether or how we could help on the long run. Let me briefly tell you what we have on our side: As you might know, YAGO is knowledge graph that has been extracted automatically from the infoboxes and categories of Wikipedia. We have evaluated YAGO manually and achieved a precision of 95%, meaning that statistically speaking, only 5 out of 100 statements in the knowledge graph are extracted wrongly. We also have a link of the Wikicategories to the WordNet taxonomy (again with 95% precision), and type checking methods for the extracted statements. Should these things ever be useful to you, we would be happy to help. I will be at the WWW conference next week. In case some of you are there, too, I'd be happy to get in touch to learn more about your current work. Thanks Fabian [1] http://yago-knowledge.org -- Thanks Fabian -- Fabian online: http://suchanek.name

[Wikidata-l] weekly summary #1
by Lydia Pintscher 13 Apr '12

13 Apr '12

Heya folks :) I'll be doing weekly summaries of what's been happening around Wikidata. This is the first one. The plan is to collect them and then make a blog post out of them every month. The wiki version of this can be found at http://meta.wikimedia.org/wiki/Wikidata/Status_updates/2012_04_13 = Development = * drafted http://meta.wikimedia.org/wiki/Wikidata/Data_model * drafted http://meta.wikimedia.org/wiki/Wikidata/Notes/API * http://meta.wikimedia.org/wiki/Wikidata/Development has useful infos for setting up a dev environment (but you probably want to wait a bit with that still until we've worked out some more quirks) * finished first scrum cycle: http://meta.wikimedia.org/wiki/Wikidata/Development/Scrum_cycle_archive ** implemented the data grid view which basically is an overview page for the data of one Wikidata item ** implemented basic functionality for editing some of the information in data grid dynamically (item label and description) with a JavaScript generated user interface ** lots of struggling with git ** created proper base for Wikibase and Wikibase Client extensions, including things such as i18n files, settings files, and a skeleton for the API ** created skeleton pages for the extensions on MediaWiki.org: https://www.mediawiki.org/wiki/Extension:Wikibase and https://www.mediawiki.org/wiki/Extension:Wikibase_Client ** WikibaseClient extension has its basic functionality implemented. Whenever a page is rendered, the extension loads the information about interlanguage links from the repository, sorts the links, and displays them. ** WikibaseClient extension also defines a new magic word/parser function {{NOEXTERNALINTERLANG}}. It can disable fetching the links from the repository completely (when used on its own as {{NOEXTERNALINTERLANG}} or with asterisk as a parameter as {{NOEXTERNALINTERLANG:*}}), or just remove the links for certain languages (for example {{NOEXTERNALINTERLANG:de|fr}} will remove the links to German and French). It remains possible to add new interlanguage links just like it is now and the new links will be sorted together with the external interlanguage links. * start of second scrum cycle: http://meta.wikimedia.org/wiki/Wikidata/Development/Current_scrum_cycle You can follow commits at https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/WikidataClient… and https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/WikidataRepo.g… (stuff not merged into master yet isn't included there) = Diskussions/Press = * Kurier: https://de.wikipedia.org/wiki/Wikipedia_Diskussion:Kurier#Wikidata (This will probably be archived soon. I will summarize and address the comments there in a blog post in the next days.) * The Atlantic: http://www.theatlantic.com/technology/archive/2012/04/the-problem-with-wiki… (please also read Denny's important comment there) * Signpost: http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2012-04-09/Wikida… = Events = * held first office hours on IRC (logs at http://meta.wikimedia.org/wiki/Wikidata/Events#IRC_office_hours) * attended/presented at the Berlin Semantic Web meetup: http://www.meetup.com/The-Berlin-Semantic-Web-Meetup-Group/events/56299712/ * upcoming: WWW2012: http://meta.wikimedia.org/wiki/Wikidata/Events = other stuff = * published team intro: http://blog.wikimedia.de/2012/04/04/meet-the-wikidata-team/ * published some basic assumptions and requirements: http://meta.wikimedia.org/wiki/Wikidata/Notes/Requirements * search for an initial logo: http://meta.wikimedia.org/wiki/Talk:Wikidata#WikiData_logo_candidate and http://commons.wikimedia.org/wiki/Category:Wikidata_logo_proposals (still have to get to promoting this and making this less painful) * volunteer page started: http://meta.wikimedia.org/wiki/Wikidata/Volunteers * collecting use-cases: http://meta.wikimedia.org/wiki/Wikidata/Queries and http://meta.wikimedia.org/wiki/Wikidata/Infoboxes If you have anything to add please share it.

Re: [Wikidata-l] Fwd: [Wiki-research-l] Wikidata opinion piece in The Atlantic

Apparently people like to criticize :) To discuss something fundamental is not criticizing. This article raises a problem we know very well à the different (linguistic, telecom, network) strata below (diversity, orthotypography, normalization, informatics, canonization, globalization, internationalization, etc. ) which now touches the semantical and intellectual strata. Engineering issues, as discussed here, are for the technical processes to work better. The problem is to determine what "better" societaly means in an "antropobotical" society (persons/robots) like ours - broadly influenced by its daily experience of Wikipedia. This leads to fundamental questions on the Freedom of Knowledge. The difficulty is the resulting ethical/technical loop and the impact on engineering orientations. jfc

[Wikidata-l] JSON-LD Provenance use case
by Gregg Kellogg 13 Apr '12

13 Apr '12

I updated the JSON Talk page [1] with an example of using the JSON-LD named-graph syntax to express provenance information about some facts, based on a discussion of the use case in the W3C RDF Working Group [2] trying to express the following: ParisFact1 expresses "Paris locatedIn France ." ParisFact1 hasReference EncyclopediaBritannica, Wikipedia, Brockhaus. ParisFact2 Paris hasPopulation 7000000^^int ParisFact2 hasReference Wikipedia The JSON-LD looks like the following: { "@context": { "rdf": "http://www.w3.org/1999/02/22-rdf-syntax-ns#", "ex": "http://example.org/", "xsd": "http://www.w3.org/2001/XMLSchema#", "ex:locatedIn": {"@type": "@id"}, "ex:hasPopulaton": {"@type": "xsd:integer"}, "ex:hasReference": {"@type": "@id"} }, "@graph": [ { "@id": "http://example.org/ParisFact1", "@type": "rdf:Graph", "@graph": { "@id": "http://example.org/location/Paris#this", "ex:locatedIn": "http://example.org/location/France#this" }, "ex:hasReference": ["http://www.britannica.com/", "http://www.wikipedia.org/", "http://www.brockhaus.de/"] }, { "@id": "http://example.org/ParisFact2", "@type": "rdf:Graph", "@graph": { "@id": "http://example.org/location/Paris#this", "ex:hasPopulation": 7000000 }, "ex:hasReference": "http://www.wikipedia.org/" } ] } Which could be expressed in TriG as: @prefix ex: <http://example.org/> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . { ex:ParisFact1 a rdf:Graph; ex:hasReference <http://www.britannica.com/>, <http://www.wikipedia.org/>, <http://www.brockhaus.de/> . ex:ParisFact2 a rdf:Graph; ex:hasReference <http://www.wikipedia.org/> . } ex:ParisFact1 { <http://example.org/location/Paris#this> ex:locatedIn <http://example.org/location/France#this> . } ex:ParisFact2 { <http://example.org/location/Paris#this> ex:hasPopulation 7000000 . } Note that JSON-LD recently added support for named graphs [3].

[Wikidata-l] Wikidata FAQ translated, and proposing my help.
by Nicolas Torzec 12 Apr '12

12 Apr '12

Dear Wikidata, I just wanted to let you know that I have spent a couple of hours translating the Wikidata FAQ into French. => See http://meta.wikimedia.org/wiki/Wikidata/FAQ/fr I also went after the first Wikidata documentation and published an introduction to the project, as a proof that I did my due diligence :) => http://zecdata.com/2012/04/09/wikidata-one-common-source-of-structured-data… I would be happy to help and collaborate if needed. (I have worked on various related topics at Yahoo! Labs and other places over the past 10+ years. So I may be of some help. Feel free to look me up on LinkedIn) Best, Nicolas.

[Wikidata-l] Data format to consider - CAP
by Pete O'Dell 11 Apr '12

11 Apr '12

The Wikidata project sounds like it can be an amazing source of information over the long term. Key to that is interoperable data with known formats that will last the test of time. If you want an electronic copy of my book (Silver Bullets) on this topic, email me and I'll send along gratis. One standard format I'd highly recommend is Common Alerting Protocol (CAP), which has been driven by OASIS (www.oasis-open.org) . CAP is becoming a worldwide standard for notification and alerting - used by FEMA, NOAA, USGS in the US gov, Australia, Canada, Sri Lanka and many other countries. Google uses CAP alerts as a basis for their new public safety alerting, and many commercial products and companies are incorporating CAP. These alerts/notifications also are useful for a historical look at events past - you can accumulate all the earthquake data for an area over a period of years.

[Wikidata-l] RDFa, Microdata and Microformats
by James HK 11 Apr '12

11 Apr '12

Hi Denny, I know everyone is still trying to organize this project but nevertheless we wanted to have some clarification about how WikiData will proceed in terms of representation of data embedded in wiki pages. Several descriptor frameworks are available [0] and MediaWiki have seen some discussions about it before [1], [2] but since this project is about semantic data it would be nice to have directional guidance about how WikiData will proceed.

by Gregor Hagedorn 10 Apr '12

10 Apr '12

Would the Word "assertion" be a possible replacement for the neonym "Snak"?
