Introduction
Texts generated by Web users are vehicles of facts, (i.e. objective expressions about entities, events and their attributes in he real world), as well as opinions, (i.e. subjective expressions of sentiments, feelings, attitudes, emotions or appraisals toward entities, events or attributes). Sentiment analysis (also called Opinion Mining) refers to the application of natural language processing and text analysis technologies to the identification and extraction of subjective information in source materials.
