从用户评价行为的时间属性——评价间隔时间入手,提出一种基于时间SFM因子的推荐攻击检测方法,通过仿真实验证明了时间SFM因子的可检测性及其阻止攻击目标项进入用户TopN推荐列表中的有效性.
Based on the time attribute of user evaluation behavior - evaluation interval time, this paper proposes a recommended attack detection method based on time SFM factor. It proves the detectability of time SFM factor and the target list entry preventing TopN from entering the user list by simulation In the validity of.
