PATENT SPECIFICATION ANALYSIS SYSTEM, PATENT SPECIFICATION ANALYSIS METHOD, COMPUTER-READABLE RECORDING MEDIUM RECORDING PROGRAM, AND PROGRAM

PROBLEM TO BE SOLVED: To facilitate the grasping of the content of a specification by a user in a patent specification analysis system for analyzing a specification related to a patent application or patent (herein after reffered to as patent specification) by extracting a word included in the specification and visually displaying its frequency. SOLUTION: A word extraction part 5 extracts the word in conformation to its descriptive column from document data of the patent specification acquired in a specification document data acquisition part 1. A word appearance frequency calculation part 3 calculates the appearance frequency of every group consisting of one or more columns according to weighting of the descriptive column, and an appearance frequency output part 4 displays the appearance frequency of each word as a graph built up for every group.
