Opinion Mining in Information Retrieval

This book discusses in detail the latest trends in sentiment analysis,focusing on "how online reviews and feedback reflectthe opinions of users and have led to a major shift in the decision-making process at organizations." Social networking has become essential in today's society. In the past, people's decisions tobuy certain products (and companies' efforts to sell them) were largely based onadvertisements, surveys, focus groups, consultants, and the opinions of friends and relatives. But now this is no longer limited to one's circle of friends, family or small surveys;it has spread globally to online social media in the form of blogs, posts, tweets, social networking sites, review sites and so on. Though not always easy, the transition from surveys to social media iscertainly lucrative. Business analytical reports have shown that many organizations have improved their sales, marketingand strategy, setting up new policies and making decisions based on opinion mining techniques.
