摘要
提出了一种粒化理论的地理本体融合方法。该方法首先运用形式概念分析地理本体,再引入粒计算理论,在不同粒度下约简概念格完成本体融合,认为地理融合过程是一个渐进过程。利用地理信息基础数据和水利空间数据进行融合实验,验证了此方法的有效性。
A geographic ontology fusion method based on granular theory is presented. First,Formal concept analysis （FCA） is used to formalize different geographic domain ontologies. Then granular computing is introduced to geo-ontologies fusion to implement concept lattice reduction in different granulations. Finally, experiments are conducted by combing funda- mental geographic information data and spatial data in the hydraulic engineering domain. The results show that G-eo-ontologies fusion is a progressive process, and the proposed method is valid in multi-source Geo-ontologies fusion. As well as merits and limitations are discussed.
