Design and Implementation of Semantic Query System Based on Ontology Context

The retrieval for educational course materials is mainly based on the keyword based match, educational course materials can not be achieved in a semantic way. The paper proposed the onto-query system, a specific semantic query system for educational domain. The paper first constructs the ontology for the instructional materials titled computer network and visualizes the representation of the ontology. Then the design and implementation architecture of ontology based semantic query system for course resources is provided. At last, the paper describes the RDF metadata description binding with ontology of course materials for computer network.
