Product information modeling of hydraulic support based on ontology

The current product information model is lack of consistent and uniform expression,especially semantic information has not been fully described,which bring about failing to meet different needs of different designers for the product information model.In addition,the product information model can not describe the function information.Aiming at these disadvantages,the paper proposed to use ontology to describe the product information model from the function layer,principle layer and structural layer.Such sub-ontology of the hydraulic support as control ontology,structure ontology and type ontology were constructed by ontology construction software protege,eventually an ontology model of the hydraulic support was integrated.The model could offer basic model for subsequent search and reuse of the hydraulic support,so as to shorten the product development cycle.Through studying the hydraulic support product information modeling based on ontology,the multi-view product information modeling method proved to be feasible,and provided method and experience for product information description based on ontology.
