Service-Oriented Search: A Ranking and Retrieval Model based on Ontology of Service Relation

Abstract

Due to the general search engine might not work well on service-based search, a novel search approach, named Service-Oriented Search, based on applying the ontology of service is proposed in this paper. The ontology which reveals the knowledge of relationship among services is constructed by extracting the working flow of the Web Services and is employed to guide the search of Web services. At the ranking stage, we develop a simple but robust strategy to measure the distance between verb term and service term in order to find out the relevant and important Web pages that cover the E-Service information of interest. At last, the experimental results confirmed that the proposed approach not only is feasible, but also outperforms the search function of Taiwan’s E-Government portal.
