    大数据领域期刊论文产出和分布

    作者简介:赵清俊(1977-),男,四川宜宾人,博士,副教授,硕士生导师,研究方向:科学计量学,技术创新和管理.

    摘 要:本文从在中观层面上对大数据领域的科研产出进行科学计量分析.对大数据科学研究的宏观层面产出和分布进行分析,为更进一步了解大数据科学研究的重要机构,方便科研人员或者企事业单位快速定位全球范围内或者某国家范围内具有重要研究能力的研究机构并开展合作、技术引进和投资等活动.

    关键词:大数据;合著;科研产出

    1.引言

    科学知识的产出和分布是了解全球关于这一科学领域的研究实力的重要指标,其已经成为对某一学科领域主题进行科学计量分析的重要组成部分.不少学者通过科学知识的产出和分布进行研究,取得了众多显著的成果.比如:著名的布拉福德定律的提出者Bradford通过对期刊的产出情况进行分析,发现了文献的分布规律;在国内,李杰等通过分析31种SCI收录的声学期刊,统计分析了国际声学研究的产出和分布提点.因此笔者在参考学者分析方法的基础上,针对大数据科学知识的产出和分布进行探索,从论文和会议报告的角度尝试挖掘出大数据科学知识的时间、空间分布的特点.

    2.论文产出和分布

    在2012年以前ARTICLE(论文)和PROCEEDINGS PAPER(报告)的文献资料都相对很少,而且2003-2011年的文献基本上处于个位数,没有明显的增长规律.到了2012年以后呈现出爆发式的增长,尤其是ARTICLE(论文)2012年,2013年,2014年的文献量几乎是前一年的3倍.虽然PROCEEDINGS PAPER(报告)在2012年开始同样具有出令人惊讶的增长量,但在2013年,2014年其文献量大致相当,并且到2015年度可检索的只有328篇,远远小于同期ARTICLE(论文)的数量,这间接说明就大数据科学的发展所举办的学术交流活动的次数呈现出稳定的变化趋势.为了更加具体的展现这两种文献资料的增长情况,笔者借助指数模型对他们的论文数量进行拟合,探究他们的增长趋势.

    从图1中我们可以看出ARTICLE(论文)呈现出指数形式的增长趋势(y等于0.318e1.055x,R2等于0.975),这在一定程度上说明对于大数据科学的研究处于持续高涨阶段.普莱斯的理论对此解释道:“学科系统的‘指数输入’(比如资金、人力资源投入等)是科学成果‘指数输出’的原因”,不少学者也对此类现象做出了解释,他们认为学科处于诞生和发展阶段,科学成果常常会呈现出指数形式的增长方式,但随着科学研究的不断进展,学科逐渐具有成熟的理论,此时学科的成果数量将增长缓慢,或者出现负增长.通过比较相同颜色的曲线,我们大致可以发现ARTICLE-TGCS等于3*ARTICLE-Recs,ARTICLE-TGCS等于5*ARTICLE-TLCS;PAPER-TGCS等于3*PAPER-TLCS.

    3.国家/地区的产出和分布

    对大数据科学文献资料的作者国籍进行统计分析,ARTICLE和PROCEEDINGS PAPER总共4140篇,涉及到的国家总共有84个,并分三个层次(总体情况,ARTICLE和PROCEEDINGS PAPER)六个指标(文献数量、文献数量百分比、TLCS、TGCS、H指数-LCS和H指数-GCS)进行统计分析,获取了发文量总数排名前二十的国家,并通过Histcite软件计算出这前二十个国家在三个层次上H指数①.从对大数据研究所涉及的国家以及文献产出统计来看,大数据科学已经受到了广泛的关注.无疑前排名前十的国家是大数据科学研究最活跃取得成果最显著的地区,他们是美国(USA)、中国(Peoples R China)、英国(UK)、德国(Germany)、澳大利亚(Australia)、加拿大(Canada)、日本(Japan)、印度(India)、韩国(South Korea)、意大利(Italy).参考以往学者的研究,我们不难发现美国和欧洲地区是目前大数据科学研究的核心地带.

    现在我们进一步分析,在进行分析前笔者发现文献中存在少部分的科研成果涉及两个或者两个以上的国家,如果单纯地将文献的著作地归属于某一个国家,这显然对其他国家不公平,而且从另一个角度讲合著的各方均参和了研究,我们假设他们的研究信息对合著者是完全彼此公开的,这就不难得出文献所蕴含的知识和技术在合著者国家间的掌握程度是彼此相当的,因此我们认为这样的情况使得各个合著国的文献量均为一篇,但这也会带来一个 效果即会使得总的文献量虚增,但相比于更加真实的反应各个国家间的差距,笔者认为这样的影响是可以忽略的.美国以发文量1417(占比28.8%),H-GCS为21位居榜首,另外在前五名中其他四个国家,中国(891,18.1%,10)、英国(265,5.4%,10)、德国(210,4.3%,10)和澳大利亚(182,3.7%,9).我们不难发现中国无论是发文总量还是H指数均远低于美国,但仅从发文数量上来看中国却比其他国家更站优势,不过我们同样也发现中国文献的H指数和其他四个国家基本无差异,这也进一步证实了我国的论文数量充足但质量上还有待进一步提高.

    4.结语

    对大数据科学研究论文数量排名前30的国家进行发文数量统计分析,这些国家前10位的发文数量就占据了全部发文数量的72.371%,到前20位时达到88.626%,到前30位时达到93.874%(如图2所示),这反应大数据科学在世界各国间的研究产出存在很大的不平衡性,存在明显的马太效应,也就是说大数据科学的研究成果和技术掌握在少数国家间.(作者单位:1.重庆师范大学经济和管理学院;2.重庆师范大学数学学院;3.重庆师范大学教务处)

    注解:

    ①H指数最早由美国加利福尼亚大学教授J.E.Hirsch教授提出用于进行科学成果评价指标,具体含义是在一定时间内发表的论文至少有H篇被引用的次数不低于H次的科研评估指标,在本处笔者将分两个环境来计量,其一就是本地下载的文献,其二是WoS数据库文献分别获得H指数-LCS和H指数-GCS.
