In this paper a new evaluation model is proposed which supports to customize evaluation attributes dynamically instead of standardized evaluation attributes Through expanding the OWL- S Ontology a Web service Ontology is constructed. Based on fuzzy theory and artificial immune network, a new data classification method, named Fuzzy C-Means artificial immune(More)
With development of SOA, the complex problem can be solved by combining available individual services and ordering them to best suit user's requirements. Web services composition is widely used in business environment. With the features of inherent autonomy and heterogeneity for component web services, it is difficult to predict the behavior of the overall(More)
Service-Oriented Architecture SOA provides a flexible framework of service composition. Using standard-based protocols, composite service can be constructed by integrating component services independently. As component services are developed by different organization and offer diverse transactional properties and QoS characteristics, it is a challenging(More)

In this paper we use prefix cache and patching algorithm which are administration way for cache. The system of proxy cache for streaming media is achieved, which is referred to operation principle of streaming media service and used RTSP protocol. In addition, it considers bytes benefit of stream media file and the size of file block, so it is more(More)
To guide the quality evaluation application of Web services in selecting from many available Web services, a evaluation model based on artificial immune network memory classifier is proposed. Evaluation tree which supports to customize evaluation attributes dynamically is defined to reveal the relation among QoS attributes. The objective and subjective(More)
ENHMM, Evaluation model of network service health level, is constructed based on multidimensional network performance. The model supports to customize evaluation factors dynamically, and gives the methods of active measurement for the network performance based on the evaluation attributes. To evaluation algorithm, AiNet immune algorithm is used, in which a(More)
As the development of Web service, reliable service quality evaluation has become the key in the service optimization. This paper addresses this problem by proposing a reliable service quality evaluation model in the Web services community. The model initially imports Web service community aiming at evaluation unreliable when involved criterions are beyond(More)
