First Claim
Patent Images
1. A system comprising:
- a text mining tool to process text in an electronic document to identify a topical expression and a polar expression in the electronic document;
a text classifier to determine a topic of the topical expression and a polarity of the polar expression, to identify a relevance of the polar expression to the topical expression, and to generate a confidence score associated with the relevance of the polar expression to the topical expression; and
a user interface to display the topical expression with the polar expression and the confidence score to a user.

Abstract
The present application presents methods for performing topical sentiment analysis on electronically stored communications employing fusion of polarity and topicality. The present application also provides methods for utilizing shallow NLP techniques to determine the polarity of an expression. The present application also provides a method for tuning a domain-specific polarity lexicon for use in the polarity determination. The present application also provides methods for computing a numeric metric of the aggregate opinion about some topic expressed in a set of expressions.
