[Wikidata-l] ISO/TC 37 Terminology and other language and content resources
by John Erling Blad 26 Mar '12

26 Mar '12

It could be interesting to check out if any of the standards published by ISO/TC 37 (http://en.wikipedia.org/wiki/ISO/TC_37) apply to this project, like * ISO 12620:2009 Terminology and other language and content resources—Specification of data categories and management of a Data Category Registry for * ISO 12200:1999 Computer applications in terminology —- Machine-readable terminology interchange format (MARTIF) —- Negotiated interchange * ISO 16642:2003 Computer applications in terminology —- Terminology Mark-up Framework (TMF) There could be others in addition to these.

Re: [Wikidata-l] [Wikitech-l] Topic Maps
by John McClure 23 Mar '12

23 Mar '12

Markus- Congrats because SMW 1.7 is a real bellringer - can't wait to upgrade. I was thinking that "named subobjects" can parallel wiki pagenames, [[#interwiki:en:ns:pgnm]]. Some namespaces would be nice to reserve would be #Dublin Core:, #OWL:, #SKOS:, #Topic Map: etc and their information elements easily defined. And should SF be able to associate forms with subobject namespaces (and categories), it seems a page can maintain a virtual wiki. What a coup! Topic maps distinguish type, subjects, scopes, names, associations & occurrences - an ISO model of an index at the back of any reference book. A minimalist implementation is to associate subjects, like categories, in a page's #DublinCore:Subject property. Subjects can be SKOS objects defined in Subject: namespace, where eg the Library of Congress Subject Headings are defined. Markup is just [[Subject:subjectname]] on any page or within any subobject. [By within, I mean a #^text property for content that's copied into a page should it be "moved" from subobject to page -- this text can contain category and subject markup too]. To be fully wiki, {{pgnm#DublinCore}} might transclude the same material as {{pgnm/DublinCore}} using this #^text property. Their idea of "type" in <xtm:scope>:<xtm:type>:<xtm:name> maps to wiki namespaces more naturally than categories can. Today, categories confuse plural lists of things with singular types of thing, causing a few practical problems. Singular nouns seem best defined in Type namespace with instances located in an appropriately named MW namespace or MW namespace alias. Note, MW can handle 64K namespaces, maybe for a seriously good dictionary of common nouns and noun-phrases like Wiktionary? A few grammatical ideas. A tilde unary operator that does a "like" page or object selection, and filters for categories and subjects that apply to pages & subobjects alike, seems valuable. A magic word {{ANAMESPACE}} ("A" prefix = "A-box") might be nice too to identify a subobject's namespace. page filters [[~{{FULLPAGENAME}}#DublinCore:]] [[Category:Active]][[Subject:LCSH Science]] subobject filters [[~{{FULLPAGENAME}}#DublinCore:]] [[#Category:Active]][[#Subject:LCSH Science]] both filters [[{{NAMESPACE}}:+]] [[Category:Active ]][[Subject:LCSH Science]] [[#Category:Active]][[#Subject:LCSH Science]] One alternative subobject naming is {{FULLPAGENAME}}#{{FULLPAGENAME}} which is a Dublin Core object ie [{{FULLPAGENAME}}#{{FULLPAGENAME}}] |?Contributor|?Coverage...|?Subject|?Title|?Type So [[Subject:pgnm]] markup for a page can be stored in the Subject property in a {{FPN#FPN}} or {{FPN#DublinCore}} object. Another approach is that mediawiki build a Category-like mechanism, with its own set of tables and indexes, for Subjects. This may boil down to which part of the wiki stack a [[Subject:pgnm]] tag best processed. I think a [[Subject:pgnm]] could be a useful addition to wiki markup so I hope that doesnt get obscured. Wikidata may want to incorporate ideas concerning Topic Maps - strategically it's possibly an easy big win, so I'll bother them too. >-----Original Message----- >From: Markus Krötzsch [mailto:markus@semantic-mediawiki.org] >Sent: Wednesday, March 21, 2012 7:43 AM >To: jmcclure(a)hypergrove.com >Subject: Re: [Wikitech-l] Topic Maps > > >On 21/03/12 13:06, John McClure wrote: >> (1) official ISO versions are purchaseable while unofficial >versions are >> foss. > >Ok, that's a pity.

[Wikidata-l] TREC KBA - Mining Content Streams to Recommend Page Updates to Editors
by John R. Frank 19 Mar '12

19 Mar '12

Data Wikipedians, The talk submission below explains my interest in structuring wikipedia for interaction with machines, so consider it my introduction to this list. I hope WikiData will provide a foundation for KBA-type algorithms (see below), and am looking forward to learning more about APIs from WikiData. -jrf http://wikimania2012.wikimedia.org/wiki/Submissions/TREC-KBA-Mining-Content… TREC KBA - Mining Content Streams to Recommend Page Updates to Editors Abstract: We have organized a new session in NIST's Text Retrieval Conference (TREC) called Knowledge Base Acceleration (KBA). TREC KBA challenges computer science researchers to develop algorithms that mine content streams, such as news and blogs, to recommend edits to knowledge bases (KB), such as Wikipedia. We consider a KB to be "large" if the number of entities described by the KB is larger than the number of humans maintaining the KB. As entities change and evolve in the real world, large KBs often lag behind by months or years. Such large KBs are an increasingly important tool in several industries, including biomedical research, law enforcement, and financial services. TREC KBA aims to develop algorithms for helping KB editors stay abreast of changes to the organizations, people, proteins, and other entities described by their KBs. In this technical presentation, we will give an overview of the TREC KBA data sets and tasks for 2012 and future years. In addition to developing text analytics, we are also working on a wikipedia bot for connecting KBA-type systems to users' talk pages in mediawiki. After presenting the current state of our bot development, we hope to engage the audience in an open discussion about how such algorithms might be most fruitfully employed in the Wikipedia community. http://trec-kba.org/ (Consider putting your name on the "interested" list in the page linked above.)

[Wikidata-l] Import from external sources
by John Erling Blad 19 Mar '12

19 Mar '12

Is there anyone that has considered how to import data from external sources, especially those that do not have any prepared an well-defined API? A rather simple example from the website for Statistics Norway is an article on a website like this http://www.ssb.no/fobstud/ and a table like this http://www.ssb.no/fobstud/tab-2002-11-21-02.html In that example you must follow a link to a new page which you then must monitor for changes. Inside that page you can use Xpath to to extract a field, and then optionally use something like a regexp to identify and split fields. As an alternate solution you might use XLT to transform the whole page. Anyhow, this can quite easily be formulated both as a parser function and a tag function. At the same site there is something called "Statistikkbanken" (http://statbank.ssb.no/statistikkbanken/) where you can (must) log on and then iterate through a sequence of pages. Similar data as in the previous example can be found in http://statbank.ssb.no/statistikkbanken/selectvarval/Define.asp?MainTable=F… But it is very difficult to formulate a kind of click-sequence inside that page. Any idea? Some kind of click-sequence recording? Statistics Norway publish statistics about Norway for free reuse as long as they are credited as appropriate. http://www.ssb.no/english/help/ John

[Wikidata-l] Introduction
by Gerard Meijssen 15 Mar '12

15 Mar '12

Hoi, The WikiData project is of real interest to me. It is very much the second coming of what is still a great idea. Providing an environment where in one central environment data is maintained. In essence data can be expressed in triples and with such a statement you get firmly into semantic web and into language technology. The original Wikidata was about "solving" the issue that Wiktionary is doing the same thing over and over again. Consider, a word like "travel" is linked on 37 wiktionaries and in essence they all say that it is an English word, a verb and has a particular meaning with translations ... on a high level all this data is the same. When you look at a word like "Nederland" at OmegaWiki, you will agree that Amsterdam is the capital of my country and this can be expressed as a "triple" and all the two other elements in this triple can be translated. Check out the word, check it out in other languages (like Arabic or Russian or Dutch) and you will find the kind of functionality that will be a challenge for this new project. Data projects, software projects have one big problem. They typically do not consider their use in other languages. They find it surprising that you can not really add all this language stuff in at a later time. Wikidata will be used by Wikipedia and Wikipedia is at this moment only some 283 languages. Not one, not two and not fifty. There are over 7000 languages in the ISO-639-3... <grin> I have been asked to be an advisor to this project and I accepted </grin> An advisor advises and my advise is to make WikiData II a tools for all our projects from the start. At OmegaWiki we learned a lot and we LOVE to share our knowledge with you. Thanks, GerardM http://en.wiktionary.org/wiki/travel http://www.omegawiki.org/Expression:Nederland
