| 英文摘要 | The description of a spatial relation is the reflection of human's cognition of spatial objects. It is not only affected by topology and metric, but also affected by geographic semantics, such as the categories of geographic entities and contexts. Currently, the researches about language aspects of spatial relations mostly focus on natural-language formalization, parsing of query sentences, and natural-language query interface. However, geographic objects are not simple geometric points, lines or polygons. In order to get a sound answer according with human cognition in spatial relation queries, we have to take geographic semantics into account. In this paper, the functions of natural-language spatial terms are designed based on previous work on natural-language formalization and human-subject tests. Then, the paper builds a geographic knowledge base based on geographic ontology using Protege for discriminating geographic semantics. Finally, using the geographic knowledge in the knowledge base, a prototype of a query system is implemented on GIS platform. |
