Title    Knowledge Retrieval and Reasoning technology Research based on Ontology                   

Abstract

In order to clearly describe the knowledge of product design , improve empirical knowledge reuse and process knowledge management level, the paper learn and absorb the ontology, deeply explore knowledge retrieval and reasoning techniques for product design based on ontology. For the expert experience in product design process, the paper sum up the logical reasoning and the constraint reasoning of design parameters，and propose a specific reasoning frame for product design based on ontology and inference rules，then detailed analyze a convert process from design rules into the rules for reasoning. On this basis, specially building a product ontology of the manipulator, By building Jena and SWRL rule base, using Jena, Pellet, Jess inference engine reasoning knowledge against design goals for the product, to achieve a power source component selection and design parameters control of manipulator product, and validate the feasibility and effectiveness of ontology reasoning framework for product design. In addition, using ontology query language SPARQL and SQWRL to conduct the concept, examples and logical relationship knowledge retrieval based on manipulator models.
