摘要
学术期刊所刊载文献的关键词反映了期刊研究的主题内容。分析一段时间内期刊关键词的聚散分布特征有助于学术期刊出版机构科学控制文稿比例,合理制定可持续发展策略,对期刊办刊水平和办刊质量的提高具有十分重要的意义。以我国情报学13种期刊为例,提取各期刊的高频关键词,利用Gini系数计算各期刊关键词的聚散度,以期刊关键词频次的均值n-和Gini系数构建二维坐标,在二维坐标中呈现并分析期刊关键词的分布特征。结果表明利用Gini系数不仅可以在表层意义上反映期刊关键词的聚散分布特征,而且可在主题内容层面上辅助评估学术期刊的办刊规模和办刊质量。
The keywords in academic journals reflect the research topis of journal.The analysis about journal keywords diversity in a certain period of time can help academic journal publishers to scientifically control the proportion of documents,rationally formulate strategies for sustainable development,which is of great significance to improve the journal quality.Taking 13 Journals of Information Science in China as examples,firstly,we extract the high-frequency keywords from journals,and construct the two-dimensional coordinates with the mean of the keywords frequency and Gini coefficient.And then,the distribution characteristics of journal keywords is analyzed in the two-dimensional coordinates.The results show that the Gini coefficient can be used not only to analyse the diversity of journal keywords in the surface sense,but also to analyse the scale and quality of journals on the content level.
