Study On Ontology-Based Machining Process Knowledge And Methods Of Retrieval

For the sake of describing Machining Process knowledge accurately, enhancing the efficiency of Machining Process knowledge retrieval and improving Machining Process knowledge level. On the basis of absorbing the fruit of ontology that is applying to knowledge management, this paper take an in-depth research on the theory and methods of building the Ontology of Machining Process Knowledge and technologies of an ontology-based knowledge of machining process knowledge retrieval.On the basis of analyzing the theory, ways of building models and characteristic of ontology when it represents the knowledge of a domain, the method of the software engineering is introduced to building ontology, a corkscrew up method of building the Ontology of Machining Process knowledge brings forward. The development of an standard, expanded and independent method and course Ontology of Machining Process knowledge is analysed by an example of building it.Analyses the deficiency of the method of being based on Key-words which is the traditional retrieval model, simple retrieval form, no treatment and understanding of domain knowledge and low precision of results, puts forward an intelligent retrieval technology which is based on the Ontology of Machining Process Knowledge, and works on the semantic reasoning about the Ontology of Machining Process Knowledge, made out effective methods which are axiom reason, out-line reason and direct reason eventually.On the basis of ontology building and intelligent retrieval of ontology technology, this paper brings forward an Ontology-Based intelligent Machining Process Knowledge Retrieval Prototype System (MPKRPS). This system arms at the Machining Process Knowledge, and takes advantage of the model of the Ontology of Machining Process Knowledge and semantic technology, which can semantic expand the word of retrieval. It gets the goal of intelligent retrieval that...
