Web service discovery is a vital problem in service computing with the increasing number of services. Existing service discovery approaches merely focus on WSDLbased keyword search, semantic matching based on domain knowledge or ontologies, or QoS-based recommendations. The keyword search omits the underlying correlations and semantic knowledge or QoS information is not always available. In this paper,...
Dynamic Web service composition is challenging problem and has been intensively investigated in recent years. Nevertheless, most of existing approaches do not provide satisfactory composition results, especially when confronted with a large scale of services. In this paper, we present a novel algorithm called HRLPLA for composing Web services. The algorithm considers functional properties and QoS...
