| 摘 要： | 目的/意义]探讨影响altmetrics覆盖率的因素,为altmetrics在学术评价中的合理使用奠定基础。方法/过程]基于Web of Science、Altmetric.com以及Mendeley,以5个学科1996-2015年间发表的所有期刊论文为分析对象,探讨学科领域、出版年份、来源期刊、国别、语种5个因素对altmetrics覆盖率的影响。结果/结论]不同altmetrics指标的覆盖率不同,Mendeley覆盖率最高,Twitter其次,而大多数指标覆盖率很低;在将altmetrics应用于期刊评价时,有必要合理鉴别和排除期刊推广策略导致的高覆盖率现象;以上5个因素均会导致期刊论文的altmetrics覆盖率差异,因此在应用altmetrics时,需要考虑到被评价对象的属性特征,必要时考虑altmetrics在这些影响因素上的标准化。

| Abstract: | Purpose/significance] The factors that affect the coverage of altmetrics are discussed, which lays the foundation for the usage of altmetrics in academic evaluation.Method/process] Based on Web of Science, Altmetric.com and Mendeley, the paper selected five disciplines' article papers published in 1996-2015, and discussed their differences of altmetrics coverage in terms of discipline, publishing year, journal, country and language.Result/conclusion] Firstly, different altmetrics indicators have different coverage, and Mendeley is the highest. However, most indicators are very low. Secondly, it is necessary to distinguish and exclude the phenomenon of high coverage caused by the promotion strategy of journals when evaluating with altmetrics. Lastly, the coverage of altmetrics for different disciplines, year of publication, journals, countries and languages is different; therefore, it is necessary to consider the differences among different papers in the above factors when evaluating with altmetrics. When necessary, standardization should be taken into account. |
