摘要:

互联网上的用户通常要求场所提供更好的购买建议。这可以由处理评级以提供推荐的信誉系统来提供。评级聚合过程是声誉系统的一个主要部分,用于产生关于产品质量的全球意见。经常使用的简单方法在计算时不考虑消费者的个人资料,无法发现新评级中出现的不公平评级和趋势。其他使用加权平均技术的复杂评级聚合方法关注消费者简档数据的一个或几个方面。本文提出了一种新的信誉系统,利用机器学习来预测消费者的可靠性,从消费者的档案。特别是,我们通过提取一组对消费者可靠性有很大影响的因素来构建新的消费者档案数据集,这些因素作为机器学习算法的输入。然后将预测的权重与加权平均方法结合以计算产品声誉得分。所提出的模型已经在三个MovieLens基准数据集上进行了评估,使用10倍交叉验证。此外,所提出的模型的性能进行了比较,以前公布的评级聚合模型。所得到的结果是有希望的,这表明该方法可能是一个潜在的解决方案的声誉系统。比较结果表明,我们的模型的准确性。最后,所提出的方法可以与在线推荐系统集成,以提供更好的购买推荐,并促进在线购物市场上的用户体验。

英文摘要:

Users on the internet usually require venues to provide better purchasing recommendations. This can be provided by a reputation system that processes ratings to provide recommendations. The rating aggregation process is a main part of reputation system to produce global opinion about the product quality. Naive methods that are frequently used do not consider consumer profiles in its calculation and cannot discover unfair ratings and trends emerging in new ratings. Other sophisticated rating aggregation methods that use weighted average technique focus on one or a few aspects of consumers profile data. This paper proposes a new reputation system using machine learning to predict reliability of consumers from consumer profile. In particular, we construct a new consumer profile dataset by extracting a set of factors that have great impact on consumer reliability, which serve as an input to machine learning algorithms. The predicted weight is then integrated with a weighted average method to compute product reputation score. The proposed model has been evaluated over three MovieLens benchmarking datasets, using 10-Folds cross validation. Furthermore, the performance of the proposed model has been compared to previous published rating aggregation models. The obtained results were promising which suggest that the proposed approach could be a potential solution for reputation systems. The results of comparison demonstrated the accuracy of our models. Finally, the proposed approach can be integrated with online recommendation systems to provide better purchasing recommendations and facilitate user experience on online shopping markets.
