摘要
首先,从空间认知语言学的角度研究了空间关系自然语言描述中谓词、量词等的分类方法;然后,在分析空间查询语言特点的基础上建立了自然语言空间查询的4类句法模式;最后,设计了一个基于自然语言空间关系的空间查询系统框架,并进行了初步实现。
In daily communication,people usually use natural language to describe the position relations between spatial entities in the real world.This expression includes the spatial predicates and the quantifiers which are used to limit the predicate.The former can be classified into topological predicates,directional predicates,metric predicates,and so on.The latter may be universal quantifiers,existential quantifiers,fuzzy quantifiers,and critical quantifiers.In order to realize the spatial query based on natural-language spatial relations,we firstly classify the predicates and the quantifiers of natural-language spatial relations based on the perspective of spatial cognitive linguistics.Then,4 types of syntax models of natural language query are established,which are consistent with the characteristics of spatial query language.Finally,a basic framework is designed for spatial query based on natural-language spatial relations.
