基于空间认知的地理信息本体语义异质分析

Semantic Heterogeneity Analysis of Geographic Information Ontology Based on Spatial Cognition

地理信息研究者受地理空间认知水平和地理信息表达方式的影响，对基于知识服务的地理信息本体的构建会产生主观意识上的偏差，导致对同名实体所创建的本体在概念描述、概念模型、概念属性等方面有所不同，从而影响地理信息本体应用过程中用户对本体的认知产生不同的理解，产生了地理信息本体异质现象。论文从研究地理空间认知的需求和目的开始，通过对地理空间认知模型、地理信息本体概念传输与形式化表达方式等进行深入分析，探讨地理空间认知差异，提取语义异质相关因素，构建基于空间认知的地理信息本体语义异质分析模型，研究地理信息本体语义异质根源问题。

Affected by the cognitive level of geospace and the expression of geographic information, the subjective understanding of geographic information researchers will vary in the construction of geographic information ontologies based on knowledge service. As a result, ontologies created by different researchers for entities with the same name may differ in concept description, conceptual model, conceptual attribute, and so on, thus leading to different user understanding in the application of geographic information ontology and the phenomenon of geographic information ontology heterogeneity. Based on the needs and objectives of geospatial cognition, the differences of geospatial cognition are explored and the semantic heterogeneity is extracted by analyzing the geographical space cognition model and conceptual transmission and formal expression of geographic information ontology. The semantic heterogeneity analysis model of geographic information ontology is established based on spatial cognition, and the basic cause of semantic heterogeneity of geographic information ontology is studied.
