Text mining method, text mining program, and text mining apparatus

摘要

To display a screen including a co-occurrence network by simple operation when designating an attention word.SOLUTION: A text mining method includes: a step for extracting a word from text data; a step for generating a co-occurrence matrix for the extracted word; a step for generating a co-occurrence network on the basis of the generated co-occurrence matrix; and a step for displaying a screen including the generated co-occurrence network. When an instruction for designating an attention word is input in a first screen including a first co-occurrence network on the basis of the whole of the designated text data, the text mining method extracts the word from limited text data constituted of a part including the attention word among the designated text data, generates a second co-occurrence matrix by using the limited text data for the extracted word, generates a second co-occurrence network on the basis of the second co-occurrence matrix, and displays a second screen including the second co-occurrence network.SELECTED DRAWING: Figure 3
