CIMS分类编码中码位依赖的研究

Research on Coding its Dependence of Classification and Coding in CIMS

通过对CIMS信息集成要求的分析 ,结合NGC CIMS分类编码系统的具体情况 ,提出了码位依赖关系。在对直接依赖、组合依赖和扩展组合依赖分析的基础上 ,就这三种依赖关系提出了码位模式分解和基于元关系的解决方法。最后根据NGC CIMS分类编码系统的实施情况 。

In this paper we propose the dependence relations of information classification and coding on the basis of analyzing the requirement of information integrated in CIMS and combining the practical implementation of information classification and coding in NGC CIMS. We firstly analyze the direct dependence, union dependence and extendedly union dependence. Then, we propose solutions for the dependence based on bits schema decomposition and meta relation. Lastly, we point out that this method is very effective on the information classification and coding system in NGC CIMS.
