Improved keyword extraction for short documents
I have a large database of historic events with descriptions that are on the order of 10-30 words each. I'm trying to build a keyword extractor that will tag each document with 1-3grams sensibly with regard to the database as a whole, so that tags will be re-used as much as possible.
TF-IDF is what first comes to mind, but I'm having poor results with, i.e., Natural.js's TFIDF tool (which doesn't use n-grams).
I've seen a lot of interesting research on more advanced ML techniques (Biterm Topic Model, unsupervised clustering, etc.) but I can't seem to find any useful implementations. Is there something out there I'm missing?
