Abstract: In the developing process of ontology engineering from pure theory to application research, the definition of ontology is too obscure and enormous to facilitate to construct, share, and reuse. Driven by the requirements on current research and application, a new definition of ontology that focuses on a domain is proposed. To unify the ideas of ontological hierarchy and modularization. Sub-ontology, atom ontology, and the recursive definition of ontology are made under summarization of the existing results. These efforts build a foundation for ontology to form the scientific taxonomic system and consistent logical theory.

Key words: ontology engineering, sub-ontology, atom ontology, recursive definition

摘要： 本体概念过分模糊和庞大，不利于构建、共享和重用。该文从当前的研究和应用需求出发，给出一个强调论域的本体定义，是完善本体逻辑理论的基础。总结已有的研究成果，基于统一本体层次化和模块化的思想，提出子本体、原子本体以及本体的递归定义，为本体建立科学的分类体系和一致的逻辑理论打下了基础。
