Enhancement Framework of Semantic Query Expansion Using Mapped Ontology

Abstract

In the present information age, providing correct information to the query with a limited concept is a challenging task. The modern adaptive Information Retrieval (IR) system is needed to provide valid information. Ontology-based on IR can provide a better solution. Ontology is a perception of shared conceptualization, represented by classes, properties, and objects. Ontology mapping offers a solution to integrate inter-domain knowledge. This paper presents a method for using ontologies to handle inter-domain query in information retrieval. Using ontology in IR for Query Expansion (QE) and document ranking seems to be the ultimate goal. The Multi-Domain Specific Ontology Mapping (MDOM) proposes the concepts derived from ontology for query expansion and information retrieval. The result shows the improvement in terms of better document ranking.
