PATENT INTELLIGENCE SYSTEM AND ITS METHOD ON MAKING SYSTEMTIC RELATION ON TECHNOLOGICAL PROBLEMS AND TECHNICAL SOLUTION

摘要

PURPOSE: A patent information system and a mapping information processing method between a technical problem and a technical solution are provided to divide, grasp, and map a technical solution task and the technical solution, thereby easily finding the technical solution of other patent related to the same or a similar technical solution task. CONSTITUTION: A dependent claim character string is obtained and parsed, and a task unit and a solution unit are extracted from the character string (S12). The task unit and the solution unit are mapped and stored (S14). A keyword group including a keyword is extracted from at least one of the task unit and the solution unit. The keyword is a simple keyword, a complex keyword, a concurrent pair, and a triple. [Reference numerals] (S11) Get one or more patent documents; (S12) Get the character strings of one or more dependent claims contained in the patent documents and parse the character strings; (S13) Extract a task unit and a solution unit from the parsed character strings; (S14) Map and store the task unit and the solution unit
