| 摘 要： | 回顾七十年代以来, 我国情报工作现代化的历史, 不难看出, 主题词典所起的重大作用。它不仅提供了计算机情报检索所需的检索语言, 并促进了我国情报工作现代化的进程。但十多年的实践, 也发现了它的许多不足: 维护的难度大和工作量大, 标引的不一致性、检索效率不理想等。在计算机的各种资源已大大丰富、要求用户友好的情况下, 作者认为主要词典应退居幕后, 采用全文检索加后控制的词表当是明智之举。

| Abstract: | By reviewing the history of modernization that China' s information business has gone through since 70’s it is no wonder to find the great role thesauruses have played.As the product of thesaurus compiling,the thesaurus has provided languages for computer information retrieval,and the effort itself has mobilized everyone in this field,and promoted the process of China' s information business modernization.Through more than one decade of practice,however , it has been found that the thesaurus has many weak points, such as the great difficulty and effort needed for its maintenance, indexing discrepancy, and unsatisfactory retrieval efficiency, The author con-siders that it would be a wise decision to allow the thesaurus to retire backstage and adopt full-text indexing with post-controlled vocabulary , with regard to the abundance of computer re-sources we already have and the requirements of user f riendliness to be met. |
