Is there a JavaScript lib/toolkit that does sentiment analysis or NLP?

Question

I've been searching around this morning, trying to find whether anyone has put together a JS lib that does either sentiment analysis (or even full on NLP) but haven't lucked into anything other than the Java lib that seems to be the standard and some ruby bits and bobs. Wondered if anyone has come across anything in JS that does more than NLP on dates?

update: I found this which seems like a reasonable PoS tagger: http://code.google.com/p/jspos/ and this may be all I need, but still welcome anyone else's finds for anything more fully featured.

Answer 1

NLP is quite heavy subject for such a lightweight language as JS. If subject is more important than the language, I'd suggest you to check out python nltk.
