在叙词表、本体等知识组织体系构建过程中,需要获取通用概念。笔者试验了三种获取通用概念的方法,一是继承传统知识组织体系通用概念,二是通过关键词在文献中词频分布情况确定通用概念,三是基于关键词总词频与标准差二维信息获得通用概念。研究结果表明:以上三种方法各有特点及使用范围,在概念获取时可以根据课题具备条件单独使用或组合使用。
In the process of constructing the knowledge organization system such as thesauri and ontology, we need to acquire the common concept. The author experimented with three methods of obtaining general concepts: one is to inherit the common concepts of traditional knowledge organization system; the other is to determine general concepts through word frequency distribution of keywords in literature; the other is to obtain two-dimensional information based on total word frequency and standard deviation of keywords Universal concept. The results show that: The above three methods have their own characteristics and scope of use, the concept of access to the subject can be used alone or in combination under the conditions.
