Abstract

Functionality-oriented service composition and quality-oriented service selection are two important phases of Web service composition. To select the optimal composition schema at the former phase and make the best composite service found at the latter phase, we propose an approach to estimate schema quality of Web service composition. The approach considers the number of Web services and the number of time steps as its evaluation criteria. Based on the two evaluation criteria, the computation formulae and algorithm are given. Finally, the effectiveness and rationality of the approach is verified through simulation experiments.
