摘　　要：实现文献分类法之间的互操作是信息组织和检索的迫切需要。目前在国内外大多数分类法之间互操作研究项目中，基本上是采用人工判断的方法来建立类目映射关系。笔者认为，《中国图书馆分类法》（CLC）和《杜威十进分类法}（DDC）的类目表达的整体概念可以分解成多个概念因素，整体相似可以建立在部分相似的基础上，可通过计算类目概念因素的相似度得到类目整体概念之间的相似度。在CLC与DDC自动映射系统中，类目表达的概念可以分解成类名词、注释词、下位词、上位词，根据相似值最大原则对概念因素进行配对，通过配对概念的加权，实现类目之间相似度的自动计算。根据类目相似值、类目对应概念因素（即对应词）的差额、相等概念因素（即等价词）的类别3个参数制订了详细的类目映射规则。本文还介绍了CLC与DDC自动映射系统的结构、功能和使用。The intereperability of classification schemes is an urgent need for information organization ＆ retrieval. Now, it is often to recognize and build up the mapping relationship between classes by hand. In our opinion, each class of CLC or DDC can be looked as an concept, and the integrity of concept can be divided into several concept elements expressed by words. We can compute the word similarity of concept elements to reflect the similarity of the integrity of class concept on the hypothesis that the integrities are similar if all the parts of them are similar. In the automatic mapping system between CLCA and DDC21, the concept of class can be divided into concept elements expressed by class headings, terms in notes, terms in lower classes and upper classes, then rank these matched concept elements of the classes between CLC and DDC according to the principle of maximum similarity. We formulated detailed mapping regulation according to three parameters： the similarity value of concept elements, the number margin of concept elements and kinds of equivalent concept elements of class. The article introduced the structure, functions and use of the automatic mapping system between CLC4 and DDC21.
