- 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.
- 为了充分体现Web服务的可信性特征和用户偏好在服务选择中的作用, 提高服务选择过程的可信性, 提出一种个性化的可信服务选择方法.定义Web服务可信性为按需定制的多维信任评估指标, 用户偏好用各维信任指标的权重值体现.提出一种层次分析法和偏好排序组织法相结合的服务选择方法.层次分析法用于计算基于用户偏好的信任指标权重值, 根据信任评估指标构建层级结构, 构造成对比较矩阵, 求解矩阵最大特征值和特征向量获得信任指标权重.偏好排序组织法用于对候选服务进行排序, 根据各维信任指标的内在特征选择合适的偏好函数, 计算候选服务的净流值获得服务排序.实验结果表明该方法可以有效地体现用户个性化的信任需求, 有效提高服务排序和选择的可信性.
