I have a set of phrases that lead to a binary outcome (accept/reject) and I was wondering what techniques are most helpful for extracting key phrases that are most likely to determine the outcome, given that I have a training set of data that has the English-language phrase and the observed outcome.
To illustrate the idea let me give a simple example:
Accepted
- Sounds great
- That would be great
- That's fine
key words: great, fine
Rejected
- I'm not sure
- I don't think so
- No way
key words: not, don't, no
