科技论文关键词标引应琢磨的几个问题

Several issues to be pondered in keyword indexing of sci-tech papers

讨论关键词标引中几个共同关心的问题。认为:关键词选用不必拘泥文章自身,也不必计较是叙词还是自由词,但要琢磨读者检索文献时的思路;在准确反映文章主题的前提下,优先选取科技文献中使用频率高的词或词组,慎用短语;关键词排列不必死抠规则或逻辑,把关系密切的词相邻排列即可。

Several issues of common concern in keyword indexing are discussed, from which it is inferred that the keywords do not have to be selected rigidly from the indexed sci-tech paper and also they are not necessarily argued to be descriptors or not, but ideas for readers to retrieve literature must be considered. Words frequently used in literature can be selected with priority provided they accurately reflect the paper＇s subject. It is also suggested that phrasal groups be cautiously used as keywords and the arrangement of keywords not necessarily stick to certain rules or logic as long as the closely l^lated words are placed adiacently.
