| Research Abstract |
The aim of this study is located in discovering the technique of text mining, which contributes to planning valid "selection and concentration" strategy of Japanese companies. In general, studies of text mining technique face to difficulties that a few important or critical words are hidden in a huge quantity of noise or meaningless words. Our study proposed two ideas or techniques in order to solve this difficulty. First, in order to make mining more accuate, original text data are given a variety of value added in digital space by attaching annotation such as words set, underline, linking origina text data with another data and so on. Second, word set are evolved in digital space or relational database in to the unmistaken direction. Finally, multivariate analysis and network analysis are applied to this coincidence matrix. Our technique is expected to discover a lot of knowledge, which will play important role in planning "selection and concentration" strategy in Japan.
