An integrated QoE and QoS based approach for web service selection
Shripad S. Joshi, O.B.V. Ramanaiah · 2016
An exponential increase in the number of web services over the last few years increases the importance of the service selection task for choosing the best among a group of web services with similar functionalities. Most of the web service selection approaches are service provider perspective based on non-functional properties such as performance, reliability etc. (such attributes known as Quality of Service or QoS). But it has been observed that in any decision support issues in selection, users' feedback (known as Quality of Experience or QoE) plays a crucial role. In this paper, an integrated model has been proposed, based on both QoE and QoS, where the best service selection is made based not only on current QoS values of the services but also users' past experience of using them. Further, the case study has been provided and the results have been analyzed by inducing users' ratings as a QoE factor along with QoS parameters. The results show that the proposed approach, augmented by user's feedback, improves the quality of selection.
