【摘要】 为了更深入理解DDC与UDC的差异,设计出更优质的知识组织系统(Knowledge Organization System),文章采用领域专家分析和量化对比方法,对最新版本的DDc和UDC工程相关范畴类目进行对比分析。分析结果表明:①DDC与UDC的知识面覆盖重合度较高;②DDC范畴类目划分整体上较UDC更为细致;⑥DDC与UDC范畴类目设置存在较大差异;④DDC与UDC的差异主要是由两者知识描述角度的差异造成的。更多还原

【Abstract】 For a more in-depth understanding of the difference between DDC and UDC to design a better knowledge organization system,the latest version of the DDC and UDC Engineering disciplines-related categories were analyzed by the authors using the domain expert analysis and quantitative comparison method.The results show that:①the knowledge coverage of DDC and UDC is high;②DDC categories are divided more minutely than UDC;③the category setting is quite different between DDC and UDC;④the differences between the DDC and UDC categories are mainly caused by the angle of knowledge describing.更多还原
