Design of Ontology-Driven Agent Based Focused Crawlers

Existing focused crawlers (FCs) are based upon fixed model of web and thus are deficient in using available information. The premise of this paper is that ontology can play an important role in enhancing the efficiency of existing agent based focused crawlers. The paper proposes an ontology driven agent based focused crawler (O-ABFC) that emphasizes on the use of ontology & contextual information in crawling. Use of ontology is emerging as a promising tool that eliminates simple keyword based crawling method as it introduces semantics or contexts in which a keyword is being searched. The major benefit of proposed O-ABFC is that it bridges the gap between the actual concept and elucidation of data and uniquely contributes to the improvement of existing web crawling techniques
