DDC到《中图法》类目映射方法研究 冰

贾君枝 郝倩倩

摘 要 对于中外分类法的映射研究，国内多关注于对计算机自动映射方法的探讨，缺乏对词表类目复杂语义关系的具
体研究。 本文在对 DDC和《中图法》理学领域共计4639个类目进行人工直接映射的基础上，通过统计其匹配依据，得出
结论：理学类目下数学、物理、化学、天文、地理等不同学科内匹配依据的总体分布呈现一致性的特点，这为检验计算机自
动匹配准确性提供了方法。 实验表明.类目名称、注释、主题词、类目关系作为主要的判断依据，占映射类目的63%，依据
匹配规则占映射的 5.14%.依据书目记录的匹配占 31 .87%，因此论文建议实现计算机自动匹配时，除类目自身信息外，
还需考虑书目记录的匹配。 图4。 表2。 参考文献6。

The Study of Ways of Mapping between Chinese Library Classification

and DDC

Jia Junzhi & Hao Qianqian

ABSTRACT The domestic rexearch of mapping between Chimse and foreign classification categories focuses more on computer
automatic mapping, but less on the complex semantic relations. On the basis of human intelligent direct mapping in the field of
science categories between DDC and Cl.C, which sums to 4639 categories, this paper has made some conclusions by calculating
the bases of direct mapping as follows: the distribution of the hases of mapping has presented uniformity in the field of science
like mathematics, physics, chemistry, astronomy and geofTaphy, which provides a method to test the precision of automatic
mapping by computer. The experiments show that, name of categories, notations, subject vocabularies, and semanUe relation-
ships, as the important basis for judgment, account for about 63% of total mapping categories, mapping regulation of categories
account for 5. 14%, arul bibliographic records for 31.87%. So it is suggested to not only take the information of categories itself
into account. but also consider hibliographic records during the automatic mapping by computer. 4 figs. 2 tabs. 6 refs.
