Aspects Regarding Detection of Sentiment in Web Content

Applications Of Sentiment Analysis

Opinions are important for humans because it influence their behavior and are a base for decision making. An important part of getting knowledge in a market field represents finding what people think about that field. People search online for comment and reviews posted by others when they want to make a buying transaction or want to inform themselves in a specific topic.

Identifying consumer opinions on a company's products is as important as knowing sales volumes, but often it is more difficult to obtain. Companies can no longer rely only on internal data in their business analysis. Current research in sentiment analysis addresses these needs of expanding the amount of information collected by companies, by analyzing the huge volume of information generated by the online social networks (Facebook, Twitter, Google+), the comments from e-commerce sites (Amazon.com) and reviews on products or services on specific platforms (Yassine, 2010).
