[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 / Significance] Using knowledge element to organize knowledge is one of the hot issues in the field of information management and information science. [Methods / Processes] Based on the analysis of existing knowledge metaphorical representations and knowledge features, Freud’s personality structure theory was integrated and a three-level and six-tuple metaphorical representation method was proposed. From the definitions , Classification and mathematical description of the three aspects of the self-level, self-level and super-level knowledge of these three levels of formal description. [Results / Conclusions] Instantiation shows how to use the knowledge element representation method to represent and organize knowledge resources. [Limitations] The theoretical research is strong in color and needs to be consummated in practical application such as identification, acquisition and storage of knowledge elements.
