Aiming to discover the most suitable service cater to the discovery request of service consumer which includes functional requirements and nonfunctional requirements, this paper proposes a service registry model named as SRC (Service Registry on Cloud) which is an extension of the keywords based service registry model and deployed as a cloud application to provide behavior-aware and QoS-aware service...
In order to improve the efficiency of service discovery and release the load of service registry, this paper proposes a service registry model named as SRMC (Service Registry with Multilevel Caches) which clusters the service consumers into groups according to their searching similarity and sets up a multilevel cache for all groups to improve the performance of service discovery. The multilevel caches...
As semantic Web services (SWS) rapidly becoming a vigorous technology research area, several large research initiatives have been produced. Meanwhile, a great deal of innovative work on semantic Web services discovery (SWSD) has been done, however, it is critical to meet the requirement of real-world applications. Hence, researchers are still seeking for better correctness and higher efficiency of...
With the widespread of Web services (WS), more deployed services are being registered into a services registry, consequently giving rise to a series of problems. A conspicuous one is the large amount of functionally equivalent Web services returned by a service registry. A plausible solution is to involve QoS (quality of service) in the services discovery. However, some existing QoS-based discovery...
