期刊论文标题与关键词表达信息的差异性分析

目的/意义]论文标题中往往包含部分或全部关键词,标题与关键词之间存在差异便于读者将二者结合,更全面地了解文献内容。方法/过程]本文首先提出了论文标题与关键词差异度的概念,然后对CSSCI中近20年的图情类期刊论文分别从差异度的年度分布、不同期刊论文差异度比较、标题长度和关键词数量对差异度的影响几个方面进行研究。结果/结论]结果表明,标题与关键词差异度有随着年份变小的趋势;有4种期刊差异度相对偏大,说明这几个期刊的标题与关键词能反映更多的内容信息;标题长度在15~30之间和关键词数在4~5个时,差异度相对较大。

Analysis of the Diversity of Information Based on the Title and the Keyword of the Journal Article

Purpose/Significance]The title of a paper often contains some or all of the key words.Readers can combine the differences between title and keywords to fully understand the content of the literature.Method/Process]Firstly this paper brought out the concept of diversity degree and its calculation method.Then it collected all papers in library and information science from CSSCI in recent 20 years.This paper studied on the distribution of the diversity degree of these papers and the 20 journals and the impact on the diversity degree of the length and the numbers of keyword of these papers.Result/Conclusion]The results showed three things,the difference between title and keyword tended to decrease with the year.There were four journals with relatively large differences which indicated the titles and keywords of these journals could reflect more content information.The difference degree was relatively large when the title length was between 15 and 30 and the number of keywords was between 4 and 5.
