An integrated approach for service selection using non-functional properties and composition context

In the maturing world of service oriented computing and Web services, we find ourselves in a position where numerous services are available, all of which address a specific need. Selecting the best such service based on the service context and a user’s current need becomes an important aspect. Services can be evaluated based on functional and non-functional criteria: the former represent the operation that the service provides, the latter criteria that differentiate functionally equal services. This chapter presents three closely related items addressing the problem of differentiating functionally equal services to find the most appropriate one in any given situation: (1) a generic and extensible model for non-functional properties, (2) a method for ranking services, and (3) an algorithm for selecting services that are part of larger execution chains. The method is evaluated, and the needs are exemplified with some motivating examples

Special Issue on Hardware Implementations of SoftComputing Techniques

This special issue targets new developments and state-of-the-art case studies of hardware implementations of soft computing techniques, including neural networks, fuzzy systems and evolutionary computation or their combination. The seven selected papers cover a wide range of approaches: at the higher level they target current-generation microprocessors or digital signal processors (DSPs), while at the lower level they deal with the design complexities of microelectronics and special-purpose VLSI devices
