面向网络的空间信息提取系统研究

随着网络技术的不断发展，互联网已经成为一个海量、复杂多样的数据源，特别是随着Web2. 0与社交网络的兴起，每个网民都可视为一个空间传感器，其源源不断地将周围的空间信息发布在网上，互联网中的空间信息日益丰富。提出了面向网络的空间信息提取系统，在从Web页面中所包含的半结构文本或自由文本中识别出完整位置的基础上，提取出与该位置相关的专题属性信息，并将其结构化和空间化。通过系统实例的研究，验证了本系统的可行性。

Web-oriented Spatial Information Extraction System

With the development of network technology, the Internet has become a complex and diverse data sources, especially the rise of Web2.0 and social networking, each Internet users can be seen as a spatial sensor from spatial information angle,massive spatial information surrounding them has been published on the Internet. Spatial information on the Internet becomes increasingly rich. This paper presented the Web oriented spatial information extraction systems. In this system, we recognize geographic sense address from non-structured data in the Web pages. Then we extracted attri bute information related to that address, and map this attribute information to spatial entity by address gcocoding. Final1y we proposed a prototype to prove the feasibility of the system.
