| 摘 要： | 提出了一种基于时空轨迹的社交亲近度模型,目的是为了解决新一代广播电视服务系统中移动手机电视用户之间控制内容分享问题。该模型首先将用户轨迹空间离散化,并将用户轨迹映射到该离散空间。然后根据相同时刻,用户之间的空间距离,计算用户之间的社交亲近度。根据亲近度,将其朋友分组,以控制分享内容。实验结果表明,该方法能够有效反映用户地理位置轨迹与用户之间的社交关系,平均分组正确率达89%。

| Abstract: | To control the content sharing between mobile television users in next generation broadcast and television service system,we formulate a model named Social Closeness Model(SCM) based on user' trajectories.In this model,we discretize the space of the users' trajectories,and map users' trajectories to the discrete space.Then,we calculate the closeness between users according the distance between them at the same time.We group the friends of the user by closeness for sharing data.Test results show the SCM can ... |
