Demo: coloring the text of the Wikipedia according to its trust
by Luca de Alfaro 01 Aug '07

01 Aug '07

Dear All: I would like to tell you about a demo we set up, where we color the text of Wikipedia articles according to a computed value of trust. The demo is available at http://trust.cse.ucsc.edu/ The trust value of each word of each revision is computed according to the reputation of the original author of the text, as well as the reputation of all authors that subsequently revised the text. We have uploaded a few hundred pages; for each page, we display the most recent 50 revisions (we analyzed them all, but we just uploaded the most recent 50 to the server). Of course, there are many other uses of text trust (for example, one could have the option of viewing a "recent high-trust version" of each page upon request), but I believe that this coloring gives an intuitive idea of how it could work. I will talk about this at Wikimania, for those of you who will be there. I am looking forward to Wikimania! Details: We first analyze the whole English Wikipedia, computing the reputation of each author at every point in time, so that we can answer questions like "what was the reputation of author with id 453 at 5:32 pm of March 14, 2006". The reputation is computed according to the idea of content-driven reputation <http://www.soe.ucsc.edu/%7Eluca/papers/07/wikiwww2007.html>. For new portions of text, the trust is equal to (a scaling function of) the reputation of the text author. Portions of text that were already present in the previous revision can gain reputation when the page is revised by higher-reputation authors, especially if those authors perform an edit in proximity of the portion of text. Portions of text can also lose trust, if low-reputation authors edit in their proximity. All the algorithms are still very preliminary, and I must still apply a rigorous learning approach to optimize the computation. Please see the demo page for more details. All the best, Luca de Alfaro http://www.soe.ucsc.edu/~luca

Question
by Tatiana Mitrokhina 29 Jul '07

29 Jul '07

Hello dear Wikipedians, my name is Tatiana. I've installed German and English wikipedia locally and tried to find out, how the Tables "Page" and "Langlinks" in the database are connected. Do you know, how it functions? I've made some attemts to get at least a title of the article and correcponding titles of it in other languages. So I took a piece of XML dump (German): - <page> <title>Actinium</title> <id>3</id> - <revision> <id>27364210</id> <timestamp>2007-02-04T20:15:45Z</timestamp> - <contributor> <username>PortalBot</username> <id>146374</id> And the numerous ids didnt let me to get the result. The matter is: In the table page page_title is Actinium and page_id is 1368. In the table langlinks ll_from is 3 In XML <title>Actinium</title> <id>3</id> . As far as I understand from the scheme of the DB table langlinks is connencted only to page table , but how? How page_id= 1368 turns to ll_from=3 and in XML id= 3. I would appreciate your help greatly. Tatiana --------------------------------- Heute schon einen Blick in die Zukunft von E-Mails wagen? Versuchen Sie´s mit dem neuen Yahoo! Mail.

New Python parser for research
by Felipe Ortega 05 Jul '07

05 Jul '07

Hi. I've just released the 'research' version of the Python parser of WikiXRay. See additional details at http://meta.wikimedia.org/wiki/WikiXRay and http://meta.wikimedia.org/wiki/WikiXRay_Python_parser This weekend, I'm uploading new graphics. I'm working on the 'plain' version of the parser, to serve as a standard info loader (including the text of all revisions, and only current versions of pages).
