INFORMATION ANALYSIS APPARATUS, INFORMATION ANALYSIS METHOD, AND COMPUTER READABLE STORAGE MEDIUM

摘要

An information analysis device (30) comprises a relevant portion identification unit (31) that compares analyzed target text with topic-related text that is written about the same event as the analyzed target text and includes information related to a specific topic, and that specifies a portion of the analyzed target text related to the topic-related text; a potential topic word extraction unit (32) that extracts a word of the specific portion; and a statistical model generation unit (33) that generates a statistical model that estimates a degree of appearance of a word on a specific topic of the analyzed target text. The statistical model generation unit (33) generates a statistical model such that degrees of appearance in a specific topic of the topic-related text word and of the extracted word are higher than those of other words.
