Abstract:

A personalized trustworthy service selection method is proposed to fully express the features of trust, emphasize the importance of user preference and improve the trustworthiness of service selection. The trustworthiness of web service is defined as customized multi-dimensional trust metrics and the user preference is embodied in the weight of each trust metric. A service selection method combining AHP(analytic hierarchy process)and PROMETHEE(preference ranking organization method for enrichment evaluations)is proposed. AHP is used to determine the weights of trust metrics according to users’ preferences. Hierarchy and pairwise comparison matrices are constructed. The weights of trust metrics are derived from the highest eigenvalue and eigenvector of the matrix. PROMETHEE is introduced to obtain the final rank of candidate services. The preference functions are defined according to the inherent characteristics of the trust metrics and net outranking flows are calculated. Experimental results show that the proposed method can effectively express users’ personalized preferences for trust metrics, and the trustworthiness of service ranking and selection is efficiently improved.
