Abstract

The invention aims to provide an abstract generation device and an abstract generation method. According to the method, words with multiple meanings can be taken into consideration for generating a proper abstract. An abstract generation device (100) comprises an article data storage part (10), a word frequency statistics part (20) and a sentence selection part (30), wherein the article data storage part (10) is used to store article data; the word frequency statistics part (20) is used to do statistics on the word frequency of each word in the article, which is represented by the article data, based on the article data, handle different word meanings as different subwords when each word in the article has multiple meanings, and do statistics on the word frequency corresponding to each subword; the sentence selection part (30) is used to select multiple sentences in the article based on the article data and the data indicating the words and subwords with the highest word frequency in all words and subwords in the article so as to generate the abstract data.

Description

technical field [0001] The present invention relates to an abstract generation device and an abstract generation method. Background technique [0002] A technique of generating abstract data representing an abstract from article data representing an article is applied for the purpose of searching for an electronic book or the like. As a step of generating an abstract, for example, there is a step of calculating a score for each sentence constituting a sentence based on various criteria and extracting a sentence with a higher score. [0003] For example, Japanese Patent Laid-Open No. 2003-281164 describes a method of using word frequency as a criterion for score calculation. This is because words with higher word frequency are presumed to be important words in the article. [0004] An article is composed of multiple sentences, and a sentence is composed of multiple words. Also, among the respective words, there are words having not only one meaning but a plurality of meani...
