Sentiment analysis from product reviews using SentiWordNet as lexical resource

In the current social, technological and economic context, customers make their decisions based mostly on the opinion of other consumers. On the other side, companies need quick feedback from their customers in order to adapt to their needs in real time. The effective connection between these two aspects relies on opinion mining tools, which automatically process consumers' reviews and opinions about products or services. This paper presents a semantic approach for a sentiment analysis application, which is based on using the SentiWordNet lexical resource. The experimental validation proved a 61% average rate of success of the application.
