Ontology-Based Web Query Classification for Information Retrieval within Digital Library

Abstract

In information retrieval system, classification of web queries is important to provide search result effectively and efficiently. Web query classification is to classify a web search query into a set of intended categories. This paper proposes the framework for providing better search results by classifying web query using domain ontology. We propose Query Classification Algorithm (QCA) for automatic topical classification of web queries based on domain specific ontology. Here, Ontology is a specialization of concepts in domain and relationships that holds between those concepts. Using ontology as a controlled vocabulary in the process of classification, accuracy value can be improved in retrieving information. The proposed system intends to provide better search result pages for users with interests of intended categories.
