PlumX评价指标对促进中国科技期刊国际传播的启示

Role of PlumX metrics in the international propagation of China's scientific journals

利用各种社交网络平台,进行科学论文的获取、分享与传播已成为当前学术交流的重要形式,为此研究社交网络对科技期刊国际传播的影响。利用Elsevier数据库整合的替代计量学指标Plum X,分析Plum X与论文被引频次的关系及其学术特征。基于《中国天然药物》单刊及药理学/毒理学学科分析,均发现高被引论文的Plum X评分显著高于低被引论文,且学科高被引论文的被引频次和Plum X评分呈正相关,此外,高质量的综述和国际论文更易获得社交网络关注。研究结果发现Plum X指标能够对单篇论文的学术影响力进行快速评价,非国际权威期刊中的热点论文也可能获得较高关注,指出英文科技期刊应重视约组社交网络平台发达和应用广泛的相关主流国家优秀稿件,合理利用社交网络平台有助于获得较高的Plum X评分,进而提升发展中国家科学家的话语权。

Social network has been becoming to be an important media for scientists to obtain,share,and propagate scientific papers.This paper is to study the impact of social network on the international propagation of scientific journals. We analyzed the relationship between the Altmetric metrics Plum X and citations by use of Elsevier database. The results from the analysis of the single journal Chinese journal of Natural Medicines and the discipline of Pharmacology and Toxicology suggest that the Plum X score is significantly higher in highly-cited papers than that of lowly-cited papers,and there is a positive correlation between citations and Plum X score in the discipline of Pharmacology and Toxicology. In addition,high-quality reviews and international papers are inclined to gain higher Plum X score. Our results support that Plum X metrics can make a quick evaluation on single paper,and indicate that hottopic paper in ordinary international journals is also possibly to obtain high attention of social network. Therefore,English-edition scientific journals should pay attention to invite and organize excellent papers from main-stream countries where social network has been well developed and used. Moreover,scientists from the developing countries should take advantage of Altmetrics to expand their scientific influences across the world.
