I want to analyze the sentiment of some books review. The db contains
- code of the book
- name of the reader
- comment.

what I would like is to give a sentiment for each reviw and then have the average of the sentiments by book, but I can't find literature about it. Someone can help me?

    Did you try the Extract Sentiment operator of Operator Toolbox extension?
