Sentiment Analysis

Implementation of sentiment analysis of app comments has begun.  We are using Python's NLTK library for tasks such as tokenization and part of speech tagging.  SentiWordNet is used as a data set for the sentiment classification of various English words.  Various algorithms that assign a positive or negative sentiment analysis score to a comment are being looked at, and some simple algorithms have been implemented.  To test the suitability of various algorithms, we are comparing the 1-5 star rating associated with the comment to the output of the sentiment analyzer.
