Web service evaluation is one of the key problems in web service discovery and selection research fields. In this paper, we propose an approach to evaluate the web service performance. Different from traditional evaluation methods, our approach is based on users experience, and we apply the idea and result in common webs evaluation fields to help construct our evaluation system. We import the Alexa...
As the emergency of considerable cloud platform, researchers and developers are turning their attentions to the architecture of cloud service environment. This paper proposed a concept of high order web service supporting MapReduce programming Paradigm and related cloud service platform architecture. Moreover, to solve the embarrassment of complicated configurations and testing, a cloud service simulation...
We propose a Discovery approach to find web services composition flows sorted by similarity. The approach extracts information from BPEL files. When creating new web services composition, the discovery result can be reused directly or provide reference. We import the lexical semantic in matching keywords. By analysis and proof, we show that our keyword splitting method can extend the application of...
This paper first presents a novel model for QoS-aware web services composition based on workflow patterns, and an executing path tree with probability. Then a discrete PSO algorithm is proposed to fit our model, which also requires some other preliminary algorithms, such as the generation of all reachable paths and executing path tree. The experiments show the performance of that algorithm and its...
Currently, discovering and composing individual Web services into more complex and more useful business process is an important challenge. Web Services deployed in P2P circumstance breaks the limitation of centralized approaches and can provide more dynamic, scalable and reliable functions. This paper proposes a peer-to-peer approach based on ontology to Web service publication and discovery used...
Web Service has emerged as a dominant paradigm for distributed computing in industry as well as academia. Current Web service discovery methods are based on centralized approaches where Web services are identified based on service functionality. However, as the number of Web Services grows and becomes more dynamic, such a centralized approach quickly becomes impractical, which suffers from problems...
As infrastructure of shared services, Web Services provides possibility for business coordination and interoperability under distributed computing environment. However, the traditional centralized Web Services architecture has its limitation and peer-to-peer computing has become a new mode for network computing on the current Internet. This paper presents an collaboratively design method of Web Services...
