I'm working on a page explaining how to Extend the Code Base for other analysis of Wiki dumps.

combinestatfiles.ml has been fixed (for some reason, it was not working right). You can find the fix in the unstable branch of git (we will move the fix to the stable branch in a little while). As a side note, development is proceeding fast these days, so you may want to make the "unstable" branch your main one.

We have a major new release of wikitrust out. The release does not contain yet on-line evaluation code: we are still working on that. However, the release contains the following improvements:
The reputation and trust algorithms have been made resistant to many form of Sybil attack. See the publications listed on UCSC Wiki Lab for further information.
Files now keep track automatically of the command line arguments, code version, and input data, used to produce them. For each file.ext generated, the tool now also writes a file file.ext.info.xml containing in xml detailed information on the software version, data, and command lines used to compute file.ext . No more loose data files nobody remembers how they were produced!
- Many small improvements and bug-fixes.
We are going to further test this revision over memorial weekend. Oh, important: to use it, you need an updated copy of OcamlLdaLibs as well!

We released a new version of the code that fixes a bug in the way reputation was computed on the basis of edit analysis. This upgrade is recommended for everybody. The bug did not affect our published results, as those were obtained before the bug was introduced.
We are working on the implementation of an on-line system for author reputation and text trust for wikis. The code will be able to color new article revisions according to trust in real-time, as the revisions are created by users. There is already some prototype code in an online directory, but that code does not work as of now. The code is still in development. The only code that works so far is the one for the batch system.

We have released the code! Most of the code is covered by the BSD license, with some Mediawiki plugins being GPL. We are currently developing an on-line version of the code, that can compute author reputation and text trust in real time, as edits are made. --Luca

We have solved our performance issues! For those of you who could not get the demo to load in the past, please try again now. --Ian

The server is up again. --Luca

Power to the campus is up again, but the server has not come up properly. We will investigate. --Luca

The demo is down, as is the main School of Engineering web site. We have had problems due to storms, and due to electrical power delivery to the campus, so we had to shut down most computers in the machine rooms. --Luca

The demo is back up! Many thanks to Heidi Sitton! The demo will be occasionally unavailable in the coming days, as work on electrical power lines on campus progresses, but hopefully the outages will be of short duration. --Luca

Unfortunately, the server we are using for the demo did not come up properly. We are investigating the problem, and we are unsure when the demo will be back up. --Luca
Dec 17, 2007
Most of the campus lost power, and the server hosting the demo did not come up after the black-out. Hopefully, the database has not been corrupted by the outage, and the server has not been damaged. We hope the demo will be back up soon. --Luca

The new demo is up! The demo consists of all the pages of the Wikipedia, as of the February 6, 2007 snapshot, the last complete snapshot we have. The next thing to do is to release the code. It should be done in a few hours. --Luca

Due to problems on one of the servers, we had to move this wiki to another server, and for a while, the URL http://trust.cse.ucsc.edu/ was not working. Our apologies! --Luca
Dec 12, 2007
All that separates us from the release of the code and the demo is a few symbolic links. Tomorrow is the day! --Luca
