Evaluating Usefulness of Reviews based on Evaluation Standpoints of Consumers

概要

Browsing product reviews is an important information resource for taking actions such as choosing and purchasing a product. However, there are a large number of reviews on electronic commerce sites; hence, it is necessary to efficiently judge the usefulness of reviews to obtain pertinent information. Conventional judging methods make the assumption that all reviews contain useful information. However, it is apparent that some reviews do not contain useful evaluation standpoints of consumers. That is, the conventional methods have the potential to not evaluate the usefulness of the reviews accurately. In this paper, we propose a method for judging the usefulness of reviews from the evaluation standpoints of consumers. To grasp the evaluation standpoints of consumers, we utilize both comprehensiveness and specificity (also known as true positive rate and positive predictive value, respectively), which can be estimated from contributory factors influencing the usefulness of reviews.
