Abstract:Therefore, the linguistic descriptions and their uncertainty of individual QoS attributes were given by the user at first, and then was to lookup the reference table to convert those into weight factors of the various QoS attributes, the last step was to use the values and weight factor of QoS attribute to evaluate the candidate services comprehensively to get the one which was closest to meets the uncertain user preferences. The results of simulation experiment show the effectiveness of the approach.
Key words:Web services selection; QoS(quality of service); user preferences; intuitionistic fuzzy sets
