Hi all! I'm looking for references about text mining methods (or text categorization in general), as much detailed as possible: algorithms, test cases, examples... of course better if using PgSQL and/or FTS ;)
Why: I'm studing a categorization method using Support Vector Machines (then supervisioned classification) and I'm using PgSQL extensively, mainly the FTS functionalities, of course ;) My method is a little bit unstable and "rough" in categorization, so I'm looking for a "trigger" to improve it. Thank you!
