we have a large database of texts (e.g. product descriptions)
and we want to extract multiple types of information (e.g. brand, release date, features, price, etc.)
what's a good library to use?
I have found many general purpose HMM libraries (such as HMM in R, GHMM, Jahmm, etc.) but I wonder which is the best suited for our problem (i.e. input is text and there are many types of "targets").
