为地理知识库构建位置本体

Building Location Ontology for Geographic Knowledge Bas

随着网络中各种地理相关的应用越来越多,要想解决地理空间信息语义层次上的应用问题,就需要用到地理知识库。其中本体是地理知识库的核心。地理本体是研究地理信息科学领域内不同层次和不同应用方向上的地理空间信息概念的详细内涵和层次关系。本文为地理知识库构建了极具实用性的的位置本体,并详细阐述了基于ETL的数据知识库从资源采集,到数据集成,最后到本体构建的过程。

With the growing number of geographic reference application on the internet, many semantic problems need to be solved through the Geographic Knowledge Base（GKB）. The ontology is the core, of GKB. Geo-ontology sludies the particular meaning and level relationships of geographic spatial information in different level and application of geographic information sciences field. This paper describes the location ontology designed for Geographic Knowledge Base, which is very useful. It also gives the detail of the GKB construction processes, from data source collection to data integration and ontology formation based on ETL.
