Research on Knowledge Ontology Retrieval Mechanism of Mine Hoist

To the problems of knowledge retrieval with related application, The retrieval mechanism for the hoist fault knowledge ontology is constructed, the retrieval processes of ontology-based hoist fault knowledge is given, including query constructor, query engine and the results custom modules.Finally, combined with hoist fault knowledge ontology, the implementation and application of system show this method help to increase the reusability and generality of the hoist fault knowledge;the system can provide users with comprehensive and accurate domain knowledge and also verify the method is effective and correct proposed in this thesis.
