化学工业领域DDC与CLC类目映射关系分析

The Analysis of Mapping Between DDC and CLC on the Chemical Industry Field

采用直接映射和同现映射相结合的方法,针对DDC23和CLC5的化学工业领域类目展开研究。将类目划分为两大类别五种类型,提出不同类型类目匹配时应遵循的基本规则;按照类目类型和级别进行统计分析,点面结合地考察DDC与CLC逻辑体系趋同和存异的变化趋势;提出映射时存在的问题及解决方案。通过类目映射关系的研究与分析,为图书情报机构的工作人员、化学工业领域的信息组织者和科研人员提供参考。

Based on the methods of direct mapping and co-occurrenee mapping, Ihe mapping belween DDC and CLC on the chemical industry field is studied. Firstly, the categories are divided into two parts and five types, then the mapping rules are discussed. Secondly, statistical analysis is discussed according to the category type and level, the logical system matching trend between DDC and CLC is showed. Finally, the problems and solutions are discussed. The study could provide references for the staff of the library and information inslilutions, chemical industry information organizers and researchers.
