Abstract

A natural language interface can make a geographic information system (GIS) easy to use. It allows one to use the natural language quickly and conveniently to operate in such as digital city management system or traffic guidance system. This paper discusses the method of nature language understanding in GIS based on ontology. Natural language understanding is general apply in computer or artificial intelligence research area, yet in GIS the natural language understanding is mainly concerned about spatial information. In order to implement the natural language understanding for spatial information perfectly we use the ontology model. First we put forward a generally process of natural language understanding in GIS, defined the conception of the ontology, next set up the ontology structure, ontology-based understanding model, also indicate the mechanism of natural language understanding based on ontology. Finally are a case study and a prototype, a discussion about the research deficiency and the development forecast of my research.
