Thumbs up or thumbs down? Detecting sentiment and opinion automatically

The web is now the place to find opinions, ideas and new trends. As marketers, politicians and strategists already know, the success or failure of a "product", widely understood, is often dependent on what people say about it on-line. Part of my research focuses on how we can automatically extract sentiment. Research on opinion and subjectivity in text has grown considerably in the last few years. New methods are being created to distinguish objective from subjective statements in a text, and to determine whether the subjective statements are positive or negative with respect to the particular subject matter. In this talk, I will describe current work that aims at determining the sentiment of a text by examining its discourse structure.
