针对移动社交网络中用户连接不确定,网络资源有限所导致的内容分享成功率低、开销大的问题,提出一种用户相似度感知的移动社交网络内容分享机制.通过分析用户行为,感知用户稳定态和变化态的兴趣度,并评估用户之间兴趣吻合度,进而结合用户交互频繁程度及用户活动区域一致性,获知用户相似度及逻辑关系.最后根据用户相似度,建立带有用户兴趣稳定态和变化态的虚拟社区,实现低成本、高成功率的内容分享.结果表明:所提机制在有效提高内容分享成功率的同时,极大限度地降低了网络开销率.
Aiming at the problem of low success rate and high cost of content sharing caused by the limited network resources in mobile social network, this paper proposes a mobile social network content sharing mechanism based on user similarity perception, and analyzes the user behavior and perceives the stability of users State of interest and change of state of interest, and assess the degree of agreement between the user interest, and then combined with frequent user interaction and user activity area consistency, access to user similarity and logic relationship.Finally, according to the user similarity, the establishment of a user interest stable State and change of virtual communities, and achieve low cost and high success rate of content sharing.The results show that the proposed mechanism can effectively reduce the success rate of content sharing, while greatly reducing the network overhead rate.
