SCH-WSD: A Semantic-Conceptual Hybrid Approach for Web Services Discovery

Abstract

Web services discovery occupies a crucial part in the semantic web, as it aims to return the most relevant web services that better meet the user’s needs. In this paper, we propose a new client-side web services architecture, designed to improve the performance of web services discovery. It is based on a hybrid approach that includes both the semantic and conceptual approach, which we called SCH-WSD (Semantic-Conceptual Hybrid approach for Web Services Discovery). SCH-WSD measures the degree of similarity between the queries and the web services using the inputs, outputs and category as matched elements. Ontology Web Language for Services (OWL-S) is used as semantic web services description language. A theoretical analysis and an experimental evaluation on some benchmarks illustrate the practical effectiveness of our approach and its ability to provide users with web services that perfectly meet their requirements.
