python-crfsuite is a python binding to CRFsuite.
pip install python-crfuite
python-crfsuite is licensed under MIT license. CRFsuite C/C++ library is licensed under BSD license.
Development happens at github: https://github.com/tpeng/python-crfsuite
python-crfsuite now detects the featue format (dict vs list of strings) automatically - it turns out the performance overhead is negligible.
- Trainer.append_stringslists and Trainer.append_dicts methods are replaced with a single pycrfsuite.Trainer.append() method;
- Tagger.set_stringlists and Tagger.set_dicts methods are removed in favor of pycrfsuite.Tagger.set() method;
- feature_format arguments in pycrfsuite.Tagger methods and constructor are dropped.
Many changes; python-crfsuite is almost rewritten.
