Knowledge push system based on work breakdown structure and ontology

Abstract

The phenomenon of knowledge overflow and knowledge disorientation is very common in knowledge-intensive enterprise, even though the knowledge management system has been used. A novel knowledge push system is designed in order to push proper knowledge actively to the proper designer at the proper time, which is oriented to the product design workflow based on work breakdown structure. The ontology models of product design task and knowledge are established, and fuzzy properties are introduced into knowledge ontology model. A similarity measurement algorithm between ontology models is proposed, which generates the knowledge matching rule. Integrating ontology construction, knowledge matching rule and knowledge control model, a knowledge push system is constructed that is used to achieve precise knowledge pushing. An electronic equipment manufacturing enterprise is taken as the application case to verify the effectiveness of the system.
