利用Web挖掘技术改善公众网络地图查询服务

Improving query services of public Web map by Web mining

针对影响公众网络地图查询服务质量的一些因素,提出利用Web挖掘技术来加以改善,这主要体现于三个环节:从万维网中发现并提取地址信息以扩充空间数据库;通过对扩充后的数据库进行空间分析与推理来增强查询功能;根据分析用户查询日志来指导数据采编工作以及提供针对性的查询服务。在文章的最后给出了原型系统的设计框架与试验实例。

This paper puts forward a method to improve query services of public web map by web mining. The improvement can be described from three facets: discovering and extracting address information from the Web to extend geocoding databases, enhancing the ability of query by spatial analyzing and reasoning on the extended geocoding databases, adjusting strategies of geocoding and providing content personalization according to patterns discovered by web map data mining. At last, the paper presents the design frame work of the prototype system and experimental results.
