| 中文摘要: |
| 轨迹可以看做是对象随着时间变化在空间中留下的印迹.近年来,随着移动终端使用的普及以及生活的信息化,大量的轨迹数据在日常生活中日益积累并为不同的应用所服务.针对用户在移动社交网络以及校园信息化统一管理平台留下的位置痕迹信息,研究和开发了多信息融合的轨迹追踪系统Argo.Argo系统分析了微博、邮件、BBS、一卡通等应用层留下的位置痕迹信息,并结合覆盖校园的无线接入点,采用无线接入点被动定位获取用户位置,实现了多信息融合下的用户轨迹追踪.实验结果表明,该系统能够有效地实现轨迹追踪,并依此提供更好的服务. |
| 英文摘要: |
| With the popularity of mobile devices and social informatization, a lot of trajectory data is increasingly accumulated in daily life and used in different applications. Based on the location information of users in the mobile social network and campus informatization management network, a trajectory tracking system named Argo is proposed in this paper. In order to realize multi-information fusion trajectory tracking, various sources of location information such as Weibo, E-mail, BBS, E-card and the passive localization information from wireless access points covering the entire campus, are all analyzed in the Argo. Experimental results show that the system can effectively achieve the trajectory tracking and provide a better service for users. |
