Osmot Search Engine

"Because learning from implicit preference data is almost as good as learning by osmosis!"

Osmot is an open-source search engine for learning ranked retrieval functions and evaluating the learned rankings. For relevant papers, see my main research page, in particular the KDD 2005 paper.

For this reason, you need to enter your email address to get instructions for downloading Osmot. The only reason I ask for this is so that I can keep track of who is using this release and notify you of any important changes.

There are three tutorials available to help you get set up running osmot:
