摘要：Much research on textual information processing focused on mining and retrieval of factual information, like information retrieval, Web search, text classification, text clustering and related text mining and natural language processing tasks. Opinions are subjective expressions describing people�s sentiments, appraisals/feelings to entities, events and their properties. A definition of opinion is very broad. In this paper, it is proposed to extract the feature set from reviews and the reviews are classified as positive or negative using Na�ve Bayes, Ada Boost and Fuzzy Lattice reasoning classifier.
