摘要 对虚拟社区中的用户进行排序并识别其中存在的特殊用户(如网络水军)是件有意义的工作。在原子轨道理论的启发下,该文将用户在虚拟社区中的活动"想象"为一种"特殊粒子"的运动,设计了计算用户"能量"的方法,进而根据用户能量等级对用户排序、识别特殊用户。通过分析仿真系统在不同条件下生成的数据,该文验证了用户能量计算方法的可行性、基于用户能量的用户排序方法的有效性。实验结果表明:该文方法的平均召回率大于82%。 Virtual communities need to rank users so as to identify special users as Internet mercenaries.Atomic orbital theory is used here to compare user activities in a virtual community to the motion of a particle.The method calculates the user energy which is used to rank and identify users.Simulations verify the feasibility of this method for user ranking with an identification rate greater than 82%.
