摘要
互联网上信息资源相当丰富,存在于各个分散的服务器上。不同的人群对信息有着各自不同的需求,导致了各种各样搜索工具和技术的产生。人们对信息获取方式便捷化的要求促使了普适计算技术的发展,普适计算设备的研发蓬勃发展,日新月异。在智能手机、电子书、PDA这些普适设备上,由于处理能力不足、带宽窄、存储空间小、网络资费高,手机屏幕小等因素,现有的搜索技术不能只是简单地移植过来。提出了一种基于普适计算的检索模型,它支持全文搜索和协同过滤技术,立足于用户设备,提供给用户高效、精确、低成本的个性化搜索结果。
Many sources of information,such as the Internet are difficult to search through.Existing tools can be frustrating for many people.So far a number of techniques have been proposed to solve user-oriented solutions.The problem re-surfaces however within a ubiquitous computing paradigm.Aside from a possible delay in response time,there are additional drawbacks with respect to mobile devices such as: bandwidth size,storage size,costs and client UI size.In this paper we introduce two search and browsing features: full text searching,collaborative filtering,all of which are centering around people.
