| Outline of Final Research Achievements |
The purpose of this study is to classify document data and give annotation words for each classification. In order to achieve this purpose, we introduce an index called "Cohesiveness" that developed the concept of cluster coefficients, and proposed a classification and annotation word assignment method based on it. In order to evaluate the validity of the proposed method, we performed computer experiments and empirical evaluations. In the empirical evaluation, we applied it to the data set of KindaiShinbun articles. In computer experiments, validity was evaluated by applying it to various data existing on the Web. In addition, the scope of application was extended to data other than document data, and it was also applied to agricultural environmental data etc.From the above, the usefulness of the proposed method became clear.
