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 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.

4. The design check knowledge construction method according to claim 1, wherein the step of associating words includes the step of, when displaying the word group in the check target knowledge definition data and the word group in the document data group, positioning the associated words close to each other or interconnecting the associated words with a line segment.

5. The design check knowledge construction method according to claim 1, wherein the step of associating words includes the step of, when extracting the word group in the document data group related to the word group in the check target knowledge definition data, presetting a keyword group for extracting a constraint condition candidate for a check item serving as the check knowledge from the words, searching a relevant document data group containing a keyword in the keyword group, making a morphological analysis of text containing the keyword, and outputting a word representing the result of the morphological analysis.

6. The design check knowledge construction method according to claim 1, wherein the step of associating words includes the step of, when presenting the word group in the check target knowledge definition data and the word group in the document data group, displaying a node representing the word group and a link representing the relationship between the words in the word group, and performing a link selection/status switching process to select a relevant link required for performing a link finalization process, which indicates the association between the words in the word group, and retain and switch the status of the link between finalized and nonfinalized.

7. The design check knowledge construction method according to claim 1, further comprising the steps of:

selecting a word from the associated words as a predefined constraint condition candidate and performing an edit on the selected word to prepare constraint data in the form of text or a mathematical expression; and

generating check data from the constraint data, the check data being designed for use with an automatic check system coordinated with a predefined list construction function.

8. A design check knowledge construction system that constructs check knowledge for evaluating design information about a design target created during design work, the system comprising:

a check target knowledge definition section that generates, from input technological basic intelligence, check target knowledge definition data, which constructs technological ontology having a tree structure or a network structure and is obtained by defining the 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;

a word association section that, in accordance with a document data group including a plurality of document data based on knowledge content concerning technological history information, extracts a word group from the document data group associated with the word group in the check target knowledge definition data, which constructs the technical ontology, and associates words in the word group with each other; and

a constraint network creating section that creates a constraint network used for a rule check from the word group associated by the step of associating words, wherein the constraint network creating section further includes;
