With the rapid development of computer technology, programming methods have changed a lot. Nowadays, software developing based on SOA (Service Oriented Architecture) is more and more popular due to its autonomous, distributed and reusable. And at the same time, user requirements are also changing, they are anxious for the information they want from the vast data, regardless of the time and space....
Academic staff at higher education institutions are crucial for quality education and research, the core competiveness of a top research-oriented university. Efforts have been made at many universities to work on a system to effectively and accurately assess the performance of academic staff to promote the overall teaching and research activities. The paper presents an appraisal information system...
Web service technologies are becoming increasingly popular for integrating systems and services. Service-oriented architecture (SOA) will provide flexible business flows for application system. This paper describes a service-oriented framework of interface prototype driven development (IPDD), and the formal description is presented, where four sub-processes are discussed respectively. An instance...
Web Service technologies are becoming increasingly popular for integrating systems and services. Web service composition as an important value-added function provides an application foundation for reusing Web services and automating composition. After brief analysis on the service composition concept and the eliciting process of functional requirements, a strategy of Web service composition based...
Proposed the services composition algorithm based on QoS which combined local strategy and global strategy for constraints. The algorithm eliminates the services with low QoS firstly and then reduces the problem of services composition plan selection for global QoS guarantee to multi-dimension multi-choice 0-1 knapsack problem which is solved by the heuristic method for improving the efficiency of...
With the evolution of service-oriented architecture, providing support for compositing distributed and autonomous Web services into business applications has become a key area in software engineering research. Flexibility of business applications will be obtained through utilizing Web services composition technologies. However, at this stage, the research on these emerging technologies dose not solve...
A key problem of the Web service is how to evaluate the reputation of the Web service. When the multiple attributive decision-making problem bases on the incomplete attribute weight and determinate attribute value, a new grey relation analysis method is proposed to solve the problem of evaluating the reputation about semantic Web service. According to the fundamental principle of the grey relation...
The important step towards Web service implement is the discovery of required services. Traditional Web service uses UDDI, WSDL standards etc. Keywords based searching is used in the traditional service discovery. For needing manual intervention and lack of semantic description, the methods before have low precision rate. Semantic Web service problem can be reduced to an assignment problem. A mathematical...
