Semantic Search Using Content Based Search Technique with Spread Activation Technique

The Semantic Web, an extension of the current web, is an emerging field with the aim of building infrastructure, wherein software agents and people can work in cooperation by sharing knowledge. The emerging Semantic Web community has proposed ontology’s to express knowledge in a machine understandable way. Using this ontology, the search engine is proposed which combines content based search techniques with spread activation techniques applied to a semantic model of a given domain. It is based on a hybrid spread activation algorithm applied to the concept instances graph to find the related concepts in the ontology based on the given query.
