Automatic Domain Sentiment Expansion

摘要

Methods and systems for automatically extending a sentiment dictionary are provided. Starting with an initial set of elements (e.g., words, emoticons, etc.) having a known sentiment, messages can be analyzed for words frequently appearing in association with such words. As a result the frequently appearing words may then be associated with a sentiment and used to help determine the sentiment of a message.
