An abstract model for e-content search using ontology

The relevant content search has become a challenging task with the increase in the availability of knowledge and volume of information on the web. Among the various factors that affect the search, the terms or keywords used in the input query has utmost effect on the retrieved results by any search application. The resultant links corresponding to a search request are dependent on the input query supplied by the user. Query expansion is the concept to expand the input query for the inclusion of more relevant terms. This study is an attempt to present state-of-art query expansion approaches along with an abstract model for e-content search in engineering domain using ontological approach. Ontology is the major focus area for semantic search where the search approaches either use generic ontology (such as WordNet) while other augment search with domain specific ontology or the combination of both.
