To extract reputations of own product from Web is important for companies. This paper proposes the method of building feature dictionary for extracting reputation information. Basic method of the dictionary building is expanding dictionaries that consist of feature expressions and evaluation expressions with syntax structure pattern. The principle of our proposed method is based on assigning a certainty factor which represents the probability that extracted words really do express a feature or evaluation expression and registering only words which have a certainty factor greater than a pre-set threshold value. We evaluated the effectiveness of our proposed method with 38,904 web documents about the mobile telephone. |
