In this work the topic of service composition scenarios is introduced and discussed with the use of leading example of service composition in the transport domain. The example is used to visualize the connection to the Internet of Things paradigm. The service composition itself is defined with a holistic approach, describing all steps of the proposed composition process like: requirements defin...

Multi-agent based semantic web service composition involves the composition of semantic web services considering each of the agent capability to serve a particular service request. This paper presents the two variations of semantic web service composition process based on the timing of negotiation in composition process. The variations are based on the concept that the negotiation between the s...

Web service composition has been one of the most researched topics of the past decade. Novel methods of web service composition are being proposed in the literature include Semantics-based composition, WSDLbased composition. Although these methods provide promising results for composition, search and discovery of web service based on QoS parameter of network and semantics or ontology associated...

To enhance the credibility of Web service composition, Pi-calculus based formal modeling of trust Web service composition is proposed. Trust Web service composition is firstly defined abstractly; then Picalculus is used to depict structure and internal interaction of Trust Web service composition, the mapping relation between trust entity and Pi-calculus is provided. Automatic reasoner MWB is a...
