To featurize pos tagged train set:
python extract_features.py train.gold.pos train.gold.feats
python extract_features.py dev.gold.pos dev.gold.feats
To train model using Mallet:
./mallet-tag.sh --train true --model-file <MODEL_FILE> train.gold.feats
NOTE: To use the mallet-tag.sh, set MALLET_HOME to where you installed Mallet.
To tag using trained model:
/mallet-tag.sh --model-file <MODEL_FILE> dev.gold.feats > output.txt
To evaluate results:
python evaluate.py <GOLD_FILE> output.txt
