摘要
针对网络拍卖中用户信任评估存在的诸多问题,提出一种综合性信任模型.该模型根据网络拍卖者的不同参与方式,将拍卖参与者划分为投标者、招标者和第三方机构/拍卖网站,综合考察影响三类参与者信任度评估的因素,如近期信誉度、时间权重、行为分析等,单独计算不同类型参与者的信任度.由于模型分角色考察参与者的信任度,降低了信任评估中干扰因素的影响,提高了该信任度计算的准确性、有效性和健全性.
A comprehensive trust model was presented mainly for the problems existed in the current assessment of trust degree in online auction. It was a fact that different participants in online auction had different viewpoints on the trust computation, such as recent credibility, time weight, value of the transaction, etc. The assessments of trust degree with multi-viewpoints of different participants being evaluated, credibility of participants was calculated separately. The comprehensive trust model was able to greatly improve the accuracy of calculation. Thus, it is more effective for analyzing the trust degree of the different participants in online auction.
