Service composition is becoming increasingly pervasive, affecting the way service computing is utilized. Service composition has become an essential element of service deployment due to the fact that single services are unable to fulfill user requirements. Owing to the dramatic growth of services claiming similar functionalities, creating a value-added composite service from a number of candida...

Web services are widely used thanks to their features of universal interoperability between software assets, platform independent and loose-coupled. Web services composition is one of the most challenging topics in service computing area. In this paper, an approach based on High Level Petri-Net model as dynamic configuration schema of web services composition is proposed to achieve self adaptat...

This paper explores service composition in pervasive environments with a focus on dynamic service selection. Service orientation offers the dynamism and loose coupling needed in pervasive applications. However, contextaware service composition is still a great challenge in pervasive computing. Service selection has to deal with dynamic contextual information to enable context-aware behaviors to...

Service composition frameworks hide the complexity of the underlying technologies and enable their users to easily compose new services from existing ones. To anticipate the reliability of composed services before their actual operations, it is possible for service composers to use existing model-based software reliability prediction techniques. However, such techniques either neglect or have o...

Web service composition is mandatory when complex functional requirements cannot be satisfied by a single Web service. Because of the exponential growth of available Web services, their automatic discovery and composition are highly desirable tasks. This paper presents a new approach for automatic Web service composition based on the formalism of Fluent Calculus using semantic service descripti...

Accelerating the development of complex and heterogeneous geographic services requires improved methods that integrate service discovery, composition, and reuse. We present an integrated use of semantic and syntactic service descriptions for service chaining, by combining an application that supports service discovery and abstract composition, with another that supports concrete composition and...

This paper presents an architecture and a methodology for agent-based Web service discovery and composition. We assume that Web services are described with declarative specifications like DAML-S. Based on the declarative information about services, symbolic reasoning can be applied while searching for or composing automatically new services. We propose that symbolic agent negotiation could be u...

This paper discusses dynamic service composition and its applicability to e-business software systems. Dynamic service composition is the process of creating new services at run-time from a set of service components. It supports business agility, flexibility, and availability – the features of critical importance in the modern business world and in eand m-commerce software systems. However, dyn...

Service-Orientated Computing (SOC) has become a main trend in software engineering that promotes the construction of applications based on the notion of services. SOC has recently attracted the researchers’ attention and has been adopted industry-wide. However, service composition that enables one to aggregate existing services into a new composite service is still a highly complex and critical...
