摘　　要：语义网中的一个核心技术就是本体及其推理机制,随着语义网技术的发展,本体在各个领域得到了广泛的应用。本体在数字图书馆提供了一种全新的知识管理模式,较好地解决了知识组织、知识检索等问题。但是目前基于本体的知识管理仅仅局限于静态知识和绝对知识,对于知识的真实性、权威性这些问题也还没有明确的解决方案。本文针对本体实现动态知识管理与控制存在的不足,作者提出了本体分子理论。文章从理论的提出、理论的形式化描述进行了充分论证,论述了分子的核子是本体不可变的属性,离子是可变的属性,只要核子相同就同属一个本体。文章以知识管理为例,详细分析了动态知识演化过程和控制管理。Ontology with its inference mechanism is the key technology of Semantic Web. With the development of Semantic Web, ontology is widely used in many domains. Ontology provides a brand new model of knowledge management, which solves the problems of knowledge organization, knowledge retrieval and so on. But nowadays, ontology based knowledge management is only restricted in static knowledge and absolute knowledge. There are no solutions for the problems of knowledge trust and belief. This paper puts forward Ontology Molecule theory, aiming at the lack of management and control strategy of dynamic knowledge. It introduces the motivation and formal theoretical definition of Ontology Molecule. In this theory, the core of an Ontology Molecule describes static properties, while the outer stands for dynamic ones. This paper also illustrates an example of knowledge management, in which the process of dynamic knowledge evolution and the control mechanism are discussed in detail.
