As some of you might remember, we have been working on author reputation and text trust systems for wikis; some of you may have seen our demo at WikiMania 2007, or the on-line demo http://wiki-trust.cse.ucsc.edu/
Since then, we have been busy at work to build a system that can be deployed on any wiki, and display the text trust information. And we finally made it!
We are pleased to announce the release of WikiTrust version 2!
With it, you can compute author reputation and text trust of your wikis in real-time, as edits to the wiki are made, and you can display text trust via a new "trust" tab. The tool can be installed as a MediaWiki extension, and is released open-source, under the BSD license; the project page is http://trust.cse.ucsc.edu/WikiTrust
WikiTrust can be deployed both on new, and on existing, wikis. WikiTrust stores author reputation and text trust in additional database tables. If deployed on an existing wiki, WikiTrust first computes the reputation and trust information for the current wiki content, and then processes new edits as they are made. The computation is scalable, parallel, and fault-tolerant, in the sense that WikiTrust adaptively fills in missing trust or reputation information.
On my MacBook, running under Ubuntu in vmware, WikiTrust can analize some 10-20 revisions / second of a wiki; so with a little patience, unless your wiki is truly huge, you can just deploy it and wait a bit. Go to http://trust.cse.ucsc.edu/WikiTrust for more information and for the code!
Feedback, comments, etc are much appreciated!

Luca, this is very good news, Congratulations! Are you in touch with the developers of media-wiki and do they know about your release? Have you any work about this being put in trial for possible deployment on wikimedia foundation projects?
Finally, I remember at your presentation in taipei you spoke about something along the lines of a "test instance". That is, the idea that every time an article is read it undergoes a test for accuracy by the reader. The more readers that don't change the text, the more "test instances" the text has passed, the more trusted that text is - This is the principle of your system correct? Well, could you tell me please what is the correct terminology for what I am calling a "test instance" and where are the (if any) academic papers/references to this concept?
I am including this trust colouring and this concept in my own thesis and can't for the life of me remember the correct terminology or find the proper reference.
All the best, -Liam Wyatt
