| 中文摘要: |
| 网络环境下，文献信息具有数量多、增长快、新词层出不穷等特点。标引是对信息资源进行组织的有效手段和重要环节，标引的质量和效率直接影响信息组织的质量和速度。对受控标引、自由标引和自动标引三种标引方式进行了相符度、专指度、标引深度及通用词数的测试对比，得出自由标引优于受控标引，自动标引优于自由标引及受控标引的结论。图1。表5。参考文献10。 |
| 英文摘要: |
| In the networked environment, document information has the characteristics of mass quantity, rapid increase and large quantity of emerging new words. Indexing is an effective measure and important part of information resource organization, and the quality and efficiency of indexing directly affect quality and speed of information organization. The authors test and compare some indicators of controlled indexing, free indexing and automatic indexing, and get the result that free indexing is better than controlled indexing, and automatic indexing is better that free indexing and controlled indexing. 1 fig. 5 tabs. 10 refs. |
