I need filtration to read tweets by keywords and Bayesian classification. Could you suggest me any client with these functions? Especially welcome if they can filtrate expanded information from links in tweets and they work on a server as CGI, or something like it.

I found a related article:

I’m very interested in the comment by Ian Mercer, but not found any related article in his site.
