All scores are (0,0)

[ayushidalmia]

Hi,

I have used senti_classifier before and it worked fine. However, I had reinstalled it and since then it is giving zero score for anything and everything. Can anyone please help?

Seems to me that it is not able to read the pickle of sentiwordnet. Thanks, will do over the weekend.
Anyways this library has some performance issues, so I have been thinking about rewriting much wiser on ruby and pack it into gem

Have you had a chance to look at what is causing this? Thanks!

Hi @ayushidalmia @cderche
Sorry guys, I had been busy. Its a dirty fix but for now the scores will cooperate !
Somehow I am not able to pickle the sentiwordnet like I was able to before. I have created a new issue for that and, will fix it (

sentiment_classifier/src/senti_classifier/senti_classifier.py

Lines 220 to 224 in cf72550

	# Fix me: TypeError: can't pickle instancemethod objects
	# Not able to dump the pickle somehow. http://stackoverflow.com/questions/16439301/cant-pickle-defaultdict
	# pickle.dump(synsets_scores, open(pickles[0],'wb'))
	#
	# Temporary Fix, just don't pickle them (it takes long time ! its better to pickle)

) soon to boost up the performance. #2

runs the code     print classify( ["The movie was the worst movie"], synsets_scores, bag_of_words)

PS: Although I have pushed the latest version of SentiWordNet 8a44b86, you can download it yourself too
