摘　　要：为了改善电商虚假评论自动识别的效果,首先从传统的监督学习方法入手对网上商品评论的真实性进行判断,进而提出了利用社交图谱识别虚假评论。这种方法基于一种假设,就是同类用户通常在是否欺骗等行为上有相似性,将其结合传统的分类学习框架进行训练分类,实验结果显示社交图谱的方法能提高5%的识别准确率。For the task of improving the performance of fake comments recognition in E-commerce, this paper firstly started with the traditional supervised learning methods to judge the truth of the online-commodities comments, then proposed the model of the social graph to identify fake comments.
