Document understanding support apparatus, summary sentence generation method, and computer-readable recording medium recording document understanding support program

摘要

A document comprehension support apparatus includes an original text analysis unit which divides an original text into significance paragraphs, the significance paragraphs being separated from each other at boundaries that are determined based on sums of points rated for individual sentences in the original text, each significance paragraph containing a group of sentences. A summarized text generating unit calculates a sum of significance indexes for each of the individual sentences contained in the significance paragraphs produced by the original text analysis unit, and generates a summarized text from each of the significance paragraphs, the summarized text containing only a predetermined number of sentences selected in order of the calculated sum of significance indexes.
