A Quality-Driven Approach for Ranking Web Services

The proliferation of Web services over the Web today has led to an increasingly complex and time consuming task for effectively discovery relevant services. One approach to improve the discovery process is considering the behavior of such services under certain conditions or considering their overall quality in accomplishing the expected functionality. In this manner, clients utilize their time more efficiently to find services of interest. In this paper, a quality-driven approach for effectively finding relevant Web services, which we call Quality of Web Service (QWS) is introduced. Results from our proposed solution demonstrate high success rate in discovering Web services of interest and that our quality-driven ranking technique outperforms current state-of-the-art keyword-based methods by at least 36.25 % in terms of precision improvement.
