B旧ozhun勺Venxian ZhUtieibico《标准文献主题词表》(Ro口T刀晚sa~)标准化领域中使用的规范化的标准文献检索辞典。又称叙词表。随着计算机在标准情报工作中的应用,标准文献主题标引的工具—主题词表的编制就提上了日程。l叨6年,国际标准化组织(】50)编写了《150主题词表》(了义)介曰~)。在此基础上,1981年法国和英国各自编制了一部多语种主题词表。法国标准化协会(月刊OR)编制的词表名为《国际技术主题词表》,由字顺表、范畴表、主题词轮排索引等部分组成;英国标准学会(璐】)编制的词表名为《根主题词表》,中文版译名为《标准文献主题词表》。它是一部主题分类合一的词表。其主表是一部按层累制分类原则和概念种属词族原则编制的分类表,全部主题词都排人体系分类表并配有惟一等级制词号,附表为字顺表。国际标准化组织(】50)分别将《国际技术主题词表》和《根主题词表》确定为150工作词表,用于国际标准信息的交流。有若干国家分别采用了两个词表。由于《根主题词表》选词立类新颖,较适于手工标引,因此中国选择了《根主题词表》作为中国标准化系统的标引词表,并编译出版了中文版,分为分类表、字顺表、英汉对照表三卷出版,现已在全国标准情报系统推广使用。为了解决两部标准主题词表不统一的问题,目前150拟议编制一部统一的150主题词表。(周洁)
