Big Group-oriented Web Service Selection Based on Hybrid QoS

Group activities in the daily lives are very popular,so the information service provider for group is required to be solved.It is difficult for Web service selection to be larger group scale and hybrid QoS model.Based on hybrid QoS model and learned from multi-attribute decision theory,big group-oriented Web service selection algorithm is presented.It includes five main steps:determining group preference,calculating weighted cluster weights,constructing cluster weighted normalized decision-making matrix,determining the positive-ideal and negative-ideal solution,calculating close-degree.Other contribution is a Web service QoS model to describe QoS information with real numbers,interval numbers and intuitionistic fuzzy numbers.Experimental results show that the proposed algorithm can solve the problem of hybrid QoS-aware big group-oriented Web service selection very well.
