我国文献分类法都是等级列举式分类法,如《中国科学院图书馆图书分类法》(简称《科图法》)。等级列举式分类法的弱点很多,如难以容纳新主题和专深主题、不适用于检索等。国际上分类语言的发展趋势是提倡以检索效率为核心的研究并由此带来了以分面分类法的编制和运用分面分析技术改造传统等级列举式分类法的研究热点。 我国对分面分类法的关注经历了介绍引进、理论研究到以《中图法》为试点的改造讨论的过程。目前,我国几大等级列举式分类法在编制体例、体系结构等方面大同小异,没有根本差
Chinese taxonomy are hierarchical enumerated taxonomies, such as “Library Classification of Chinese Academy of Sciences” (referred to as “Kotu law”). The hierarchical enumeration has many weaknesses, such as difficult to accommodate new topics and deep themes, does not apply to search and so on. The development trend of classification languages in the world is to promote research centered on retrieval efficiency and bring about the research focus of reforming the traditional hierarchical enumerated taxonomy by using the method of faceted classification. Our attention to the faceted classification method has undergone the introduction and introduction, and theoretical research has been made to the process of reforming the discussion with the pilot project of “Chinese Library Classification” as the pilot. At present, China’s several major categories of enumerated taxonomies in the preparation of systems, architecture, etc. are more or less the same, there is no fundamental difference
