How may I use CRF in NLTK?

Question

In NLTK like HMM tagger, there seems to be CRF tagger also. But I am not finding any tutorial or help. How should I do it?

Answer 1

Really really late answer on this one, but just in case you wanted to have an example, you can find one here. Also note that this CRF interface is not an interface to Mallet, but it is an interface to CRFsuite
