Abstract

Disclosed is a design check knowledge construction system that adequately improves the quality of check knowledge and fully enhances the quality of a product, which is a final target to be checked. The system includes a check target knowledge definition section and a word association section. The check target knowledge definition section generates check target knowledge definition data, which is obtained by defining check target knowledge (check knowledge) that serves as a target field to be checked, in accordance with the relationship between a word group and words in the word group and with reference to technological ontology concerning technological basic intelligence input from a user input/output section. The word association section extracts a word group from a document data group associated with the word group in the check target knowledge definition data and associates words in the word group with each other in accordance with the document data group including a plurality of document data based on knowledge content concerning technological history information stored in a document data database.
