As a result, there has been a trend to develop systems that can automatically summarize opinions from a set of reviews. In this respect, the automatic classification and information extraction from users’ comments, also known as sentiment analysis (SA) becomes vital to offer users the best responses to users’ queries, based on their preferences. In this paper, a novel system hat offers personalized user experiences and solves the semantic-pragmatic gap was presented.
