基于Web文本的开放式空间信息查询

Open Spatial Information Query Based-on Web Text

  • 摘要: 本文通过分析Web文本中空间信息的语言特征,研究了空间信息的Web获取与匹配等关键问题,进而提出了在GIS空间数据库的基础上,以开放式的数据获取方式增强空间信息查询能力的基本方法与系统架构。通过开放式空间信息查询系统的实例研究,验证了方法的正确性。

     

    Abstract: In this paper,language features of spatial information in web texts are firstly analyzed.Then essential methods about online extraction and matching of spatial information and are studied.On the basis of GIS spatial databases,a framework and several methods about expanding the abilities of spatial information query are proposed by keeping data acquisition method in an open style.Related case studies were performed to verify the correctness of the methods.
