A Service Mining Approach for Time Estimation of Composite Web Services

Response time of web service is one of the most important features of SOA-based application. This paper proposes a time estimation method for composite web services based on mining historical execution information of web service in the dynamic environment. Firstly, it gives frame and format for the service log collection, and then it analyzes the extracting service execution time and network transmission time, and constructs service network based on the service behavior interaction. Secondly, the paper presents the method of forecasting composite service execution time and also provides the measure of environmental availability and time availability.
