本文旨在设计和实现基于同现映射的分类知识组织体系互操作系统。并以杜威分类法和中图分类法为例,在建立和分析DDC与CLC类目对应关系的基础上,对MARC或EXCEL格式的记录进行数据解析、自动匹配和结果输出,从而实现DDC与CLC类目的自动转换。 The purpose of this paper is to design and implement a classified knowledge organization system interoperability system based on co-occurrence mapping. Taking Dewey classification and China map classification as examples, based on the establishment and analysis of the corresponding relationship between DDC and CLC categories, the data of MARC or EXCEL records are analyzed, automatically matched and the results are output, so that DDC and CLC Automatic conversion of categories.
