Web Service QoS Prediction Method Based on Time Series Analysis

The QoS (quality of service) of Web services will fluctuate according to the variations of Internet environment and server loads. Therefore, the key question in the service computing areas is how to help users select appropriate Web Service. This paper presents a Web Service QoS prediction method based on time series analysis to address the above question. And it accomplishes the tool of predicting Web Service QoS automatically. This tool can predict the QoS information in the short future according to the historic data of Web Service. And the experiments verify the effectiveness of the method based on the historic data from 17832 services.
