Abstract

Quality of Service (QoS) has been widely used to support Web Service selection and composition. Thus, QoS is very important for users to select the most suitable Web services. In this paper, we proposed a method to measure QoS of Web services. The key of the approach is to use Bayesian Network to measure each QoS value of Web services. The experimental results show that our proposed method can measure QoS of Web services effectively.

Abstract

One key technology in web service composition systems is how to find a set of suitable web service candidates with regard to a user’s requirement. In this paper, we proposed a web service discovery approach. The approach adopts skyline computing to find the most suitable service for users with low cost. Experimental results show that our proposed approach is very effective for QoS-aware service composition system.
