With the rapidly increasing consumer-generated content on the web, there is
great demand for automatic analysis of the sentiment expressed in this
content. Companies are interested in how the consumers rate and evaluate their
products and services, politicians are interested in perceptions of their
campaigns, and regular web users are interested in customer reviews when
shopping online. Over the past several years, the number of studies in sentiment and subjectivity detection has increased accordingly, and so have its applications.
