texai.org
Stephen Reed is doing some interesting research at texai.org. This project is interesting to me because there is a lot of overlap with my own KBSportal.com project (which I am currently re-writing in Ruby and Ruby on Rails: the first two versions were in Common Lisp and Java): RDF, Sesame, knowledge representation, and NLP.
For me, working on KBSportal.com has been a learning process, and I think that texai also serves that purpose for Stephen.

RapidMiner machine learning, data mining, and visualization tool
When analyzing data for customers I usually start with a tool like Weka or occasionally write custom analysis code. The GUI tool RapidMiner (used to be called YALE) provides a nice environment for setting up experiments by selecting operations and models to apply to your data sets. RapidMiner uses Weka, libsvm, JAMA, and several graphics visualization libraries. RapidMiner has data loaders for relational databases, spreadsheets, comma delimited files, etc.
It is well worth watching the demo video for a quick introduction before working through the tutorial.
