A Service Selection Workflow for Composition Using Correlation and Route Optimization

Chin-Chih Chang, Young-Lin Lo
2015 2015 7th International Conference on Computational Intelligence, Communication Systems and Networks  
Web services have been widely accepted as a server-side technology and are the key component to cloud computing. How to effectively compose a service from a number of services is a still an issue.  ...  The highly ranked services are selected to construct a service graph determined by the correlation values among them.  ...  Effective dynamic Web service composition is still a highly complex and challenging task. In this paper we propose a selection framework for composition which is feasible and not complex.  ...
