Usage

To train models:

$ ./trainer.py -k 1 -s laplace -f savefiles/somefile -p data/corpora/posrev_train.txt -n data/corpora/negrev_train.txt

(will create/overwrite the file "savefiles/somefile")

To classify a review using trained models:

$ ./classifier.py -f savefiles/somefile

This will wait for input from stdin. Example:

$ ./classifier.py -f savefile
"This movie sucks balls"
NEGATIVE

or:

$ echo "This movie sucks balls" | ./classifier.py -f savefile
NEGATIVE

To make a full test of the trained models:

./tester.py -f savefiles/somefile -p data/corpora/posrev_test.txt -n data/corpora/negrev_test.txt
