Text structure analyzing apparatus, abstracting apparatus, and program recording medium

摘要

A text input section (1) divides an inputted text into sentences and attaches a number to each of the sentences, which is stored in a text data base together with the number. An important word recognizing section (2) generates a list of important words for each sentence to store it in a storing section (8). An important word weighting section (3) weights each important word. A relation degree computing section (4) computes a relation degree between an attention sentence and a precedent sentence. An important degree computing section (5) computes an importance degree of each attention sentence. A tree structure determining section (6) determines a parent sentence of the attention sentence and determines a tree structure of the inputted text. Unlike the case of determining whether or not character strings of key words are merely coincident with each other, it is possible to determine a parent sentence of each sentence based on a degree of connection between two sentences and analyze a structure of the inputted text with high accuracy according to the above construction.
