"Grouping Text Files"
Next challenge in my attempt to learn RM.
I have a collection of text documents. (Maybe 1,000)
IF possible, I would like to use RM for the following:
1) Automaticaly cluster them. (I've seen great screenshots of the results, but have no idea how to do it.)
2) Do some kind of "best feature" extraction - Use TFIDF or other algorithm to find significant 2-word and 3-word features
3) Maybe do some kind of sentiment analysis. (I read a great press release about how RM was used for looking and consumer opinion of a laundry detergent. That is amazing. How was this don.)
