摘要

PROBLEM TO BE SOLVED: To provide a method for extracting a topic group adaptive for a document group by using an existing topic group attached to an existing document group and a method for classifying document groups for every topic suitable for the document group. SOLUTION: This document group processing method comprises an existing topic group probability model construction step for constructing the probability model of an existing topic group, an adaptive topic group extraction step for extracting a topic group matched with a document group by using the probability model constructed by the existing topic group probability model construction step and a document group classification step for classifying the document groups for every adaptive topic group extracted by the suitable topic group extraction step.
