摘要
智能GIS的最终目标是实现用户与GIS的自然语言交互。如何从自然语言中自动抽取空间信息,消除GIS中结构化空间信息与自然语言中非结构化空间信息之间的语义障碍,已成为智能GIS面临的两大难题。目前的相关研究主要集中于自然语言空间关系。空间词汇及其句法模式是自然语言空间关系研究的核心问题。本文首先阐述了自然语言空间关系研究的几个基本问题,然后详细讨论了汉语中描述各种空间关系的空间词汇及其句法模式。最后,探讨了GIS中自然语言空间关系查询请求表达的句法模式及其解析方法。
The purpose of intelligent GIS is to realize the natural main problems of intelligent GIS are how to automatically extract to bridge the semantic gap between unstructured mation in GIS. The previous research focuses on language interaction between GIS and users. Two spatial information from natural language and how spatial information in natural language and structured spatial infornatural-language spatial relations. One of its basic tasks is to ex-plore spatial terms and syntactic patterns in natural language. In this paper, the basic problems of natural-language spatial relations are described, and then Chinese spatial terms and syntactic patterns are discussed in detail, Finally, a few syntactic patterns are presented for query representation of natural-language spatial relations in GIS.
