Assisting Trustworthiness Based Web Services Selection Using the Fidelity of Websites

Web services selection aims to choose an appropriate web service among a number of service candidates. The trustworthiness of web services is an important metric for web services selection. Many trustworthiness based web services selecting methods have been proposed in the academic community. However, the fidelity of web service's supporting websites (e.g. the websites providing the service, or referencing the service.), as an important factor for the evaluation of web services’ trustworthiness, is often ignored. This leads to that existing methods cannot provide service consumers with a comprehensive view of the web services. In this paper, we propose a method to estimate the fidelity of web services’ supporting websites, and present a novel trustworthiness based web services selection approach using our estimation result. A case study conducted in this paper indicates that, by using our approach, we can provide active assistance for service consumers during web services selection.
