基于语义一致性的多层本体元模型构建方法研究

Research on Construction Method of Multi-Layer Ontology Meta-Model Based on Semantic Consistency

为了解决各领域知识的语义异构,实现知识共享,需要建立统一的本体模型框架和方法体系。在分析其他本体构建方法特点的基础上,提出了多层本体元模型构建思想。首先,利用顶层本体描述无具体领域特征的普遍联系;然后,通过上层本体描述各领域基本特征的核心类与关系;最后,基于应用本体描述明确领域内的具体实例。在此基础上,构建了三层本体元模型。通过5W1H分析法归纳了顶层本体的概念与关系,设计了三层本体元模型的概念模型,保证了本体全局的语义一致性;通过模块的裂变、重组、复用,实现了本体的模块化构建;以情境模型为例,构建了通用的情境本体实例。最后设计了通用本体的语义一致性检验方法,以提高本体建模效率,保证语义一致性要求。

To solve the semantic heterogeneity of domain knowledge and realize knowledge sharing, a general model for domain ontology and normative method system should be developed. Based on the analysis of other ontology construction method characteristics, this paper proposes the idea of a multilayer ontology meta-model. Top-level ontology is used to describe the widespread contact of all domains; upper ontology, to describe the core classes and relationships of basic features in various domains; and application ontology, to describe a concrete instance within a clear domain. On this basis, this paper builds a three-layer ontology meta-model. The concepts and relations in the top-level ontology are summarized by the 5W1H analysis method. The conceptual model is designed to ensure semantic consistency for global ontology. The modular building of ontology is implemented through module fission, reorganization, and reuse. The general context ontology instance is built using a context model. Finally, the general ontology semantic consistency check method is designed to improve the efficiency of ontology modeling and ensure the requirement of semantic consistency.
