| Abstract(in English) | Text mining technique is classified into “birds-eye type”, in which words with much frequency of appearance are payed attention and “pinpoint focus type”, in which words with important meaning in a particular context in spite of little frequency of appearance are payed attention. In this article, authors propose the technique that users for text mining discover at pinpoint the text block every five sentences where solution is written, and express its meanings as “basic phrase”. To put it concretely, first, basic phrase with dependency relation is created from text block which is more likely to contain solutions. Next, a few of text blocks similar to this text block are discovered based on cluster analysis, and basic phrase is evolved, refering to these text blocks. In this way, only necessary parts are extracted from enormous text data including ambiguity, and deep and rich knowledge can be acquired. |
