Abstract(in English) | Our paper proposes a method, based on content-based recommendation, for extracting feature terms that can express product features from customer reviews on e-commerce sites. We define the features of a product as those features that reviewers considered them to be the advantages and disadvantages of a product. Therefore we extract them as features of the product that made a sufficiently strong impression on reviewers. The approach involves extracting opinion sentences from customer reviews, and recognizes each evaluated term as a candidate for product features. Using the positive opinion ratio of each candidate as the extent of how divided reviewers' opinions are, we extract the feature terms of the selected product by considering the feature score based on the positive opinion ratio. We conducted an experiment to evaluate the usefulness of extracted feature terms. |
