Opinion Mining and Sentiment Analysis are natural language processing tasks which aims at:

  • detecting the presence of opinions within a resource; and,
  • classifying this resource according to the opinion they express about a given subject.

Generally speaking, opinion mining and sentiment analysis aim at determining the attitude of a speaker or a writer with respect to a topic or the overall tonality of a document. In the recent years, the exponential increase in the use of the Web for exchanging public opinions about events, facts, products, etc. led to an extensive usage of opinion mining and sentiment analysis approaches, especially for marketing and social purposes.
