Development of Indian Agricultural Research Ontology: Semantic Rich Relations Based Information Retrieval System for Vidyanidhi Digital Library.

Digital Libraries represent semantically rich collections of digital documents. Ontology-based information retrieval systems capture semantic relations for providing value added information services. Deviating from the regular approach of developing ontologies on the basis of domain knowledge, the present paper puts forward a novel method for developing ontologies from the semantic information available in the titles of digital documents. Such an approach gathers significance due to its simplicity in ontology development process. To examine the same, the study considered the case of Agricultural Electronic Theses and Dissertations (ETDs) present in Vidyanidhi Digital Library. The study resulted in the development of Indian Agricultural Research domain ontology, which was used for developing ontology-based information retrieval system. This paper while describing the methodology followed for developing the ontology presents the technical details of the developed system. [ABSTRACT FROM AUTHOR]
