<P>PROBLEM TO BE SOLVED: To provide a lexical analysis method, a lexical analysis program, and a lexical analysis system, which calculate correlations between a plurality of themes to calculate data for objectively determining differences between them. <P>SOLUTION: The lexical analysis system is provided with an operation means and an extraction result storage means, and the operation means compares text data stored in an evaluation sentence storage means with vocabularies stored in a vocabulary storage means and extracts the same vocabularies from the text data to detect the number of vocabularies, and extracted vocabularies and the number of vocabularies are stored in the extraction result storage means. Text data is inputted from a text data input means and is stored in the evaluation sentence storage means, and the operation means extracts vocabularies from the text data and extracts the same vocabularies as evaluation reference vocabularies stored in the vocabulary storage means and detects the number of extracted vocabularies, and the degree of correlation is calculated which is a ratio of the number of vocabularies extracted from the text data and that stored in the evaluation sentence storage means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
