Ontology Based Semantic Search: An Introduction and a Survey of Current Approaches

Abstract

Ontology based semantic search will lead to new generation of search based on the meaning of keyword rather than keyword and helps in finding correct information on the web. Here, ontology provides an explicit specification of conceptualization which helps to connect the information on the existing web pages with the background knowledge. Ontology based search overcomes the semantic gap between the keyword found in documents and those in query. This survey provides an introduction to ontology based semantic search and review the different details of selected ontology based search approaches and compare them by means of classification criteria. Based on this comparison, this survey attempts to identify the possible directions for future research.
