ABSTRACT
The QoS-aware web service composition (WSC) problem aims at the automatic construction of a composite web service with the optimal accumulated QoS value. It is, however, intractable to solve the QoS-aware WSC problem for large scale instances, since the problem corresponds to a global optimization problem. In this paper, we propose a novel anytime algorithm for the QoS-aware WSC problem to identify composite web services with high quality much earlier than an optimal algorithm and the beam stack search [3].

Web service composition: a reality check
WISE'07: Proceedings of the 8th international conference on Web information systems engineeringAutomated web service composition is one of the major promises of service-oriented architecture, where services can be discovered and composed dynamically and automatically. To investigate the methods for composite web service construction, we conducted ...
