Research on Construction of Knowledge Ontology for Product Design Based on OWL

摘要

The traditional description language and tools can not be fully and accurately classify and describe the product designing knowledge.Ontology is a formal description for an important and shared concept in a specific domain.This paper based on the idea of Ontology,makes classification and concept extraction for design knowledge of enterprise products from the perspective of Ontology;uses the OWL ontology description language to describe formally the ontology knowledge for product design;defines the ontology model by the OWL restriction axioms,then constructs an OVVL-based knowledge ontology model of product design.This ontology model can commendably solve the problem of knowledge sharing and reuse for product design,provide the semantic foundation for the knowledge integration of product design,and make sure the computer can effectively carry out intelligent retrieval of design knowledge.Finally,we take the automobile modeling design as an example to introduce the ontology construction of automobile modeling design knowledge in details.
