Part-of-Speech Tagging
Our part-of-speech tagger uses the generalized model from dynamic model selection and utilizes ambiguity classes trained on a large corpus. It processes over 82K tokens per second on an Intel Xeon 2.30GHz machine and shows the state-of-the-art accuracy (97.64% on the WSJ corpus).
