摘　　要：[目的/意义]研究Altmetrics指标在科学出版物中的存在现状,探讨Altmetrics指标与传统文献计量指标之间的关系,有利于更好地探索Altmetrics指标在科研评价方面的潜在意义和价值。[方法/过程]选取Altmetric.com提供的科技领域学术出版物的Altmetrics指标。利用Web of Science获取出版物的被引次数、期刊影响因子、学科归一化被引、学科归一化期刊影响因子指标。采用因子分析、Pearson相关性分析方法检验各指标的相关性。利用Precison-Recall分析方法检验Altmetrics指标能否比期刊影响因子更好的识别高被引论文。[结果/结论]拥有Altmetric分数的学术论文大多为最近年代出版,且论文主要集中在生物医学和健康科学、社会科学与人类学、生命和地球科学领域,预示着大众媒体对这三个领域的科技论文有较高的兴趣。Altmetrics指标与被引次数、期刊影响因子之间的相关关系为正相关但较弱,Altmetric分数在过滤高被引论文方面弱于期刊影响因子指标。因此,Altmetric分数反映出跟引文数不同的学术影响力,Altmetrics指标可以作为引文分析的辅助工具,相互补充但不可替代。[ Purpose/Significance ] The paper researches on the presence of altmetrics in scientific publications and the relationship with bibfiometric indicators. More research is suggested to find the potential evaluation of altmetrics. [ Method/Process] The paper selects air- metrics indicator from altmetric, corn,and gets citation,JIF,NCS,NJIF indicators matched with web of science. Combined with factor anal- ysis and Pearson correlation analysis, it examines the correlation of indicators. Using the Precision-Recall analysis method, it finds out whether Altmetrics can better identify highly cited papers than JIF. [ Result/Conclusion ] Our results confirm that altmetric data concentrat- ed on the most recent publications,and mainly concentrated in the biomedical and health sciences,social sciences and humanities,life and earth sciences,indicating the public interest for these three fields. The correlation between altmetric and citations,JIF is positive,but weak. Altmetric score is weaker in filtering the highly cited papers than JIF. So,altmetric score reflects the different academic impact as citations, altmetrics indicator can be used as complementary tool for citations.
