This is a C++ implementation of the part-of-speech (POS) tagging algorithm by Tsuruoka et.al. This is trainable with your own POS-annotated corpus.

cd lapos-X.X/ make

Prepare the input in one-sentence-per-line format, then run the "lapos" command:

echo "He opened the window." | ./lapos -t -m ./model_wsj02-21 He/PRP opened/VBD the/DT window/NN ./. How to build a tagging model with your own annotated corpus

Please see the README file.
