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.
