摘要

PROBLEM TO BE SOLVED: To accurately extract trace information.;SOLUTION: An element information acquisition section 12 acquires requirement element information and requirement element item information contained in a requirement definition description and acquires design element information and design element item information contained in a basic design description, and a design element candidate determination section 18 extracts a combination in which product aggregates are not empty sets among the acquired design element item information and generates a sum aggregate of the extracted design element item information. A trace candidate determination section 16 then extracts one of the requirement element information items acquired by the element information acquisition section 12, compares requirement element item information that the requirement element information has with the sum aggregate and, if the requirement element item information is contained in the sum aggregate equal to or more than a predetermined ratio (equal to or more than a threshold value), extracts as trace information a pair of the requirement element information corresponding to the requirement element item information and a plurality of design element information items corresponding to the sum aggregate.;COPYRIGHT: (C)2013,JPO&INPIT
