二维网络信息聚合的研究与系统设计

Research and system design of two dimensional Web information syndication

根据基于地理位置坐标或区域的网络信息聚合（WIS）的方式,建立了将与地理位置相关的信息和地图上的地理位置特征有机结合的二维网络信息聚合（2-DWIS）服务系统模型。该系统通过一个地理层次数学模型,挖掘并利用互联网信息中的地理要素,提供给用户更直观便捷的信息抽取、检索和展现的新体验,帮助用户在海量信息源中迅速找到真正需要的信息。通过系统的体系架构描述和针对旅游领域的系统设计和实验示范,说明二维地理模型与网络信息聚合的有机结合,可优化用户的交互体验和提高检索效率。

According to the method of Web information syndication （WIS） based on geographic coordinates or regions, a 2- DWIS service system which combines the location-related information with the geographic nature of maps was constructed. This system applied a geographic hierarchical mathematical model to extraction and use of the location properties in Web information, and then delivered to users a new kind of experience of information extraction, retrieval and presentation. As the result, this system helped users to locate Web information more quickly and more accurately. This paper gives out the system architecture in detail, the system design for travel service domain, as well as the demonstrations of the experiment.
