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!
