【摘要】：随着移动互联网和电子商务的迅猛发展,纷杂的商务移动应用和商务信息让用户们应接不暇,传统的用户主动去服务器获取信息的方法不仅浪费了用户宝贵的时间和流量,还增加了服务器的压力,降低处理效率,己不再适用。服务器主动向用户推送是解决这一问题的有效方案。而如今的推送服务仍有几点不足,首先现在的推送服务多为广告形式,服务器将某一条信息推送给所有的用户,这对于多数用户来说是无效信息,不仅浪费用户的流量还会对用户产生一定的困扰,降低了用户体验；其次现在的推送服务没有充分利用用户的地理信息为用户提供更人性化的推送。因此,本文中针对上述不足,设计并实现了一种基于用户偏好和地理位置信息的即时推送,利用标签系统描述用户偏好的方法,并根据对标签的权重计算和再赋值建立完整的加权标签网络模型来分析用户的偏好。进一步将标签与资源结合起来,完成标签一地理位置之间的双向映射,构建完整的基于用户偏好和地理位置的个性化推送模型。同时,将这个模型实现在基于Android智能手机平台的无线信息分享系统一-Rendezvous中,使用XMPP协议实现系统推送消息的通信,并对系统功能做了详细的测试。本文提出的推送方法提高了用户的满意度,提升了用户体验。且此方法与Rendezvous系统的耦合度比较低,是一种通用的方法,经过简单的处理和优化,可以提供为一套应用程序接口,应用到各种移动信息分享应用中,有相当的应用意义。对Rendezvous系统的需求分析,架构设计和测试方案是一套完整的流程,可作为其他系统开发的标准规程作为参考。
[Abstract]:With the rapid development of mobile Internet and electronic commerce, users are overwhelmed by various business mobile applications and business information. The traditional methods of users taking the initiative to go to the server to obtain information not only waste the precious time and traffic of users. It also increases the pressure on the server, reduces the processing efficiency, and is no longer applicable. The active push of the server to the user is an effective solution to this problem. But today's push service still has several shortcomings. First of all, most of the push services are in the form of advertisements. The server pushes a certain piece of information to all users, which is invalid information for most users, which not only wastes the user's traffic, but also causes certain troubles to the users. It reduces the user experience; secondly, the push service does not make full use of the user's geographic information to provide users with a more humane push. Therefore, this paper designs and implements an instant push method based on user preference and geographical location information, and describes user preference by label system. According to the weight calculation and re-assignment of labels, a complete weighted label network model is established to analyze users' preferences. Furthermore, the label and resources are combined together to complete the bidirectional mapping between labels and geographical locations. A complete personalized push model based on user preference and geographical location is constructed. At the same time, the model is implemented in the wireless information sharing system-Rendezvous based on Android smart phone platform, and the system push message communication is realized by using XMPP protocol, and the function of the system is tested in detail. The push method proposed in this paper improves user satisfaction and user experience, and the coupling degree between this method and Rendezvous system is relatively low, it is a general method, after simple processing and optimization, Can be provided as a set of application program interface, applied to various mobile information sharing applications, has considerable application significance. For Rendezvous system requirements analysis, architecture design and testing scheme is a complete set of processes, It can be used as a reference for other system development standards.
