空间SQL（Structured Query Language）是系统解决地理问题的有力工具，但在地理问答问题中的应用并不广泛。本文介绍了一种参数化的方法，将自然语言的地理问题转换为空间SQL。特别是，三种类型的复杂性，并提出了初步的解决方案来处理这些复杂性。整个参数化过程的实现，以生成空间SQL模板的五种类型的地理问题。有人建议，我们的方法是有用的解决自然地理问题，如在GIS中的空间功能。
Spatial SQL (structured query language) is a powerful tool for systematically solving geographic problems, however, it has not been widely applied to the problem of geographic question answering. This paper introduces a parameterized approach to translate natural language geographic questions into spatial SQLs. In particular, three types of complexity are introduced and initial solutions are proposed to deal with these complexities. The entire parameterization process is implemented to generate spatial SQL templates for five types of geographic questions. It is suggested that our approach is useful for solving natural geographic problems using spatial functions such as those in a GIS.
