WCRFT is a morphosyntactic tagger for Polish. The tagger brings together Conditional Random Fields (CRF) and tiered tagging.

The code is written in Python, but using C++ components:

  • CRF++ classifier,
  • WCCL: formalism for morphosyntactic feature generation (and its implementation),
  • corpus2: a library for rapid NLP application development, supporting positional tagsets.
