Respected Sir,

http://wordnet.princeton.edu/wordnet/download/current-version/
i have downloaded (Download tar-bzip2'ed: WordNet-3.0.tar.bz2)
i extract it in the folder wordnet.
i have so many problems :
1 When i use it in the rapid miner it gave me sentiment =0, for the input text=  "this movie is good".
2) For pos tagging when i try to tag the text. it gave me nothing.
3) For filter token (jj.*) , again i didnot get the expected results
