SIMILAR CONCEPT EXTRACTION SYSTEM AND SIMILAR CONCEPT EXTRACTION METHOD USING GRAPH STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To derive similar concepts in consideration of the relationship of concepts between a plurality of categories. PSOLUTION: Concepts belonging to a plurality of categories are displayed with a graph with concepts as nodes and the relationship of concepts as edges, and cross-edges between categories are reduced, so that it is possible to derive similar concepts from many-sided points of view in consideration of the relationship of concepts between categories.
