Re: Any successful experiences for text classification ?
hi chee wu :
the easiest way is to realize ur goal i think. but the carrot2 's
performance is not very good. and the another important thing is that u
should input the data with as little spam as possible , or u will get
useless result.

that's right, carrot2 just used to clustering documents, but not to classify
them.

Carrot2 performs document clustering, which, as opposed to document
classification, is an unsupervised technique (no predefined categories).
Therefore, Carrot2 doesn't seem suitable for this particular problem.
Thanks,
