摘　　要：[目的/意义]采用知识元方式进行知识组织是当前信息管理和情报学领域的热点研究问题之一。[方法/过程]在分析现有的知识元表示方法和知识特征基础上,融入弗洛伊德的人格结构理论,提出了一种具有三层次、六元组的知识元表示方法,分别从定义、分类和数学描述三方面对本我层、自我层和超我层这三层次的知识元进行形式化描述。[结果/结论]实例化说明了如何运用该知识元表示方法进行知识资源表示与组织。[局限]理论研究色彩较强,在知识元识别、获取、存储等实际应用方面有待完善。[ Purpose/significancel Nowadays, knowledge organization using the method of knowledge element has been one of the most popular research topics in the field of information management and information science. [ Method/process ] Based on the analysis of existing knowledge representation methods and knowledge features about knowledge element, combining the Freud＇ s theory of personality structure, the paper proposes a representation method of knowledge element with three levels and six attributes. This method gives a formal description of knowledge elements involving Id layer, Ego layer and Super layer respectively from the definition, classification and mathematical description. [ Result/conclusion ] In the end of the paper, an example is analyzed to show how to make knowledge resources representation and organization by the method of knowledge element representation. [ Limitations ] The paper mainly discusses in theoretical level, and the practical applications such as the identification, acquisition and storage of knowledge element should be further studied.
