In the service-oriented architecture, component services can be composed to provide value-added services. The notion of composite service skyline facilitates obtaining a QoS-optimal service combination. State-of-the-art approach to computing composite service skyline assumes that candidate services of different tasks are independent. However, real-word services are usually QoS-correlated. To this...
Currently, the number of Web services on the Internet is growing exponentially. Faced with a large number of functionally equivalent candidate services, users always hope to select the optimal one that can provide the best QoS values. However, users usually do not know the QoS values of all the candidate services as the limited historical service invocation records. Different QoS prediction methods...
Battlefield situational information discovery is a key part of information distribution, based on ontology model theory, this paper describes the information service concepts and relationships among them, then get battlefield situational information description in semantic level, then modify the feature weight calculation in TFIDF formula to improve the accuracy of service matching, filter out irrelevant...
The development of service-oriented applications grows rapidly these years and gains more and more attention both from industry and from academe. Service-oriented applications are assembled from building blocks called service components whose profiles are defined by service specifications. When the dynamic changes happen in the service-oriented architectures, the service discovery and substitution...
In recent years, service-oriented computing and pervasive computing are emerging as the next computing paradigms. Applying service-oriented technologies in smart space, a typical pervasive environment, facilitates the interaction of heterogeneous service components and the construction of pervasive applications. However, it also raises the new challenge of extending service specifications, composing...
