摘要: 建立了一个基于本体的地理信息查询系统(OGIIS)。通过对地理本体实例的语义推理和索引,OGIIS实现了对地理实体中语义关系的查询,解决了传统的地理信息查询中无法对语义关系进行查询和推理的问题,提高了地理空间语义网上对异构数据信息检索和查询的智能性和准确度。

关键词: 地理空间语义网, 地理本体, 地理信息检索

Abstract: This paper builds an ontology-based geographic information inquiry system(OGIIS). Through semantic reasoning, geographic information retrieval and ranking, OGIIS can be performed more precisely and intelligently than traditional ones. The semantic relations contained in the geographic information can be explicitly represented and searched.

Key words: geospatial semantic Web, geographic ontology, geographic information retrieval
