Conceptual framework for Ontology Based Information Retrieval System for Indian regional language

Over the years, the volume of information available through the World Wide Web has been increasing continuously; unfortunately, the unstructured nature and huge volume of information accessible over networks have made it increasingly difficult to find the relevant information. The information retrieval techniques commonly used are based on keywords, wherein provided keyword list doesn´t consider the semantic relationship between keywords nor it consider the meaning of words and phrases. With such system, users frequently have problems expressing their information needs and translation those needs into requests. To overcome the limitations of keyword-based information retrieval, one must think of introducing conceptual knowledge to information retrieval which will help users to formulate their request. The semantic knowledge attached to information is united by means of ontologies. The mapping of concepts in information into conceptual models i.e. ontology appears to be useful method for moving from keyword based to concept based information retrieval. This paper proposes conceptual framework for Ontology Based Information Retrieval System.
