基于地名本体的地名知识表达方法

摘要

Toponym knowledge reflects how people describe geographic named entities in real world. How to organ-ize and manage toponym knowledge effectively to share and reuse it based on semantic level is an important re-search subject. In consideration of people commonsense spatial cognition of people and space-time characteristic of toponym, a toponym knowledg unified representation model ( TKURM) based on toponym was presented, which contained toponym ontology, spatio-temporal rule base and spatial metaknowledge. The toponym feature, toponym type, geometry shape, spatial relation and time model were anylized which belonged to toponym ontology. A build-ing procession of toponym knowledge base based on TKURM was designed. Finally the application analysis was made which took Zhengzhou administrative region toponym knowledge base as an example.%地名知识反映人们对客观世界地理命名实体的描述，如何对地名知识有效地组织和管理，实现语义级别的共享和重用是一项重要的研究课题。顾及人的常识性空间认知和地名的时空特征，提出了一种基于地名本体的地名知识统一形式化表达模型( TKURM)，该模型包括地名本体、时空规则库和空间元知识，并对地名本体的地名要素、地名类型、几何形态、空间关系和时态模型做了具体分析。基于TKURM设计了地名知识库的构建流程，并以郑州市行政区划地名知识库为例进行了应用分析。
