| 中文摘要: |
| 科技论文中存在大量不能反映论文主题的无效关键词，降低了论文显示度和学术影响力。本文作者以中国知网为文献检索数据库，针对科技论文中“应用”“对策”“问题”“管理”“设计”“措施”“影响”“现状”“研究”“发展”这10个常见无效关键词展开计量学分析，发现2015—2019年这10个常见无效关键词的出现频率相对稳定，其共现关键词中无效关键词的比例非常高；“学院学报”及“硕士论文”中常见无效关键词的累计词频明显比“大学学报”以及“博士论文”的高，说明前者的关键词标引质量较差，因此，科技论文作者及审读编校人员应重视关键词标引工作，避免因使用无效关键词而降低文献传播效果。 |
| 英文摘要: |
| There exists a great amount of keywords that cannot reflect the theme accurately in scientific papers, which reduces the accessibility and academic influence of the scientific papers. In this paper, CNKI was used as the document retrieval database. Metrological analysis of 10 common invalid keywords in scientific papers was carried out, including “application” “countermeasure” “issue” “management” “design” “measure” “influence” “present situation” “research” and “development”. It is found that occurrence of the above 10 common invalid keywords in scientific papers is relatively stable, and the proportion of invalid keywords is remarkably high in the co-occurrence network of these 10 keywords from 2015 to 2019. The accumulative word frequencies in scientific papers published by college journals and Master's thesis are obviously higher than that in scientific papers published by university journals and doctoral dissertations in the past 5 years, which indicates that the indexing quality of the former is better than that of the latter. Thus, the writers, tutors, reviewers and editors of scientific papers are suggested to pay more attention to the indexing of keywords, so as to avoid unsatisfactory viewed times of scientific papers due to usage of invalid key words. |
