| 1 | The R-and AR-indices:Complementing the h-index显示文摘Based on the foundation laid by the h-index we introduce and study the R- and AR-indices. These new indices eliminate some of the disadvantages of the h-index, especially when they are used in combina-tion with the h-index. The R-index measures the h-core’s citation intensity, while AR goes one step further and takes the age of publications into account. This allows for an index that can actually in-crease and decrease over time. We propose the pair (h, AR) as a meaningful indicator for research evaluation. We further prove a relation characterizing the h-index in the power law model. | JIN BiHui LIANG LiMing Ronald ROUSSEAU Leo EGGHE | 2007 | Chinese Science Bulletin2007，52，6： | 116 |
| 2 | R指数、AR指数:h指数功能扩展的补充指标显示文摘分析了h指数功能扩展后在科学家个人科研绩效评价中的三个缺陷,即缺乏灵敏度,缺乏区分度,缺乏波动性。针对这些缺陷,提出了R指数和AR指数。R指数用于解决h指数的灵敏度和区分度的问题;AR指数用于解决h指数只升不降的问题。利用17位普赖斯奖得主的论文数量和被引频次数量进行了h指数、R指数和AR指数的测算。针对h指数与R指数或AR指数配伍使用后的双因素问题,设计了标准化(h,R)指数和等效(h,R)指数。实测数据证明R指数和AR指数是h指数功能扩展的补充指标。 | 金碧辉 Rousseau Ronald | 2007 | 科学观察2007，2，3： | 177 |
| 3 | Hirsch指数研究的新进展显示文摘提出了离散Hirsch指数(简称h指数)的精确定义,引入了“Hirsch核心”这一概念。不仅将h指数推广到实数集,还介绍了其他相关的派生指数,g指数和A指数。只有h指数和g指数相结合,才能较全面地评价科学家的科研成就。 | Ronald Rousseau 刘俊婉(翻译) 马建华(审校) | 2006 | 科学观察2006，1，4： | 80 |
| 4 | 期刊评价:影响因子及其相关指标显示文摘概括介绍了国外学者近十年来有关期刊质量评价的研究工作,重点介绍了国际上学者们对影响因子在期刊评价中的作用所持的不同观点,概述了影响因子的不同计算方法以及影响因子在科研评价中的利用。 | Ronald Rousseau 金碧辉 | 2001 | 中国科技期刊研究2001，12，1： | 71 |
| 5 | 用共关键词网络揭示领域知识结构的实验研究显示文摘本文利用Web of Science数据库,构建出数学、电化学、信息计量学和传播学4个领域的高频共关键词网络。用于反映领域核心知识。此类网络以关键词为节点,当两个关键词用于同一论文中时就形成节点之间的连接。核心/边缘分析和网络分析参数表明核心关键词数量增长速度低于关键词总量增速。依据核心关键词表达核心知识概念的逻辑,推论特定知识领域中稳定的核心概念及其共现网络反映了该领域相对稳定的核心知识及其结构。 | 叶鹰 张力 赵星 Ronald Rousseau | 2012 | 情报学报2012，31，12： | 33 |
| 6 | 案例研究:美国信息学会会刊h指数的时间序列变化显示文摘在本期《科学观察》中已有文章对h指数的优缺点及其普遍性问题进行了讨论,如讨论了h指数在期刊评价中的应用。Braun等曾对期刊的h指数做了界定:对于一种期刊,如果期刊发表的论文中有h篇文章每篇被引用数至少为h,同时要满足h这个自然数为最大。那么h即为该期刊的h指数。在本篇短文中,我以美国信息科学学会期刊(JASIS)(1991~2000年)为例, | Ronald Rousseau 刘俊婉(翻译) 金碧辉(审校) | 2006 | 科学观察2006，1，1： | 29 |
| 7 | SCI的引文统计指标及其与研究评价的关系显示文摘从引证类型和检索系统统计源期刊组成分析SCI的引文统计数据及相关指标与期刊和论文学术水平间的不对应关系,并从引文统计时段、论文类型和期刊大小等方面探讨影响因子本身的不确定性;通过分析中国科技期刊的被引情况指出SACI中引文数据的统计错误。认为在我国的科研成果和学术期刊评价中,一定要具体分析SCI的统计数据,适度、合理地使用引证分析方法。 | 任胜利 Ronald Rousseau 祖广安 | 2003 | 编辑学报2003，15，1： | 30 |
| 8 | A multi-metric approach for research evaluation显示文摘Background information is provided about the Web 2.0 related term altmetrics. This term is placed in the context of the broader field of informetrics. The term influmetrics is proposed as a better term for altmetrics. The importance of considering research products and not just scientific publications is highlighted. Issues related to peer review and making funding decisions within a multi-metric approach are discussed and brought in relation with the new metrics field. | RONALD Rousseau FRED Y Ye | 2013 | Chinese Science Bulletin2013，58，26： | 25 |
| 9 | h指数研究在2007-2008年的新进展显示文摘该文对近期(2007-2008年)h指数及其衍生指数的发展进行了简单的回顾。 | Ronald Rousseau 李志忠(翻译) | 2008 | 科学观察2008，3，3： | 17 |
| 10 | A view on big data and its relation to Informetrics显示文摘Purpose:Big data offer a huge challenge.Their very existence leads to the contradiction that the more data we have the less accessible they become,as the particular piece of information one is searching for may be buried among terabytes of other data.In this contribution we discuss the origin of big data and point to three challenges when big data arise:Data storage,data processing and generating insights.Design/methodology/approach:Computer-related challenges can be expressed by the CAP theorem which states that it is only possible to simultaneously provide any two of the three following properties in distributed applications:Consistency(C),availability(A)and partition tolerance(P).As an aside we mention Amdahl’s law and its application for scientific collaboration.We further discuss data mining in large databases and knowledge representation for handling the results of data mining exercises.We further offer a short informetric study of the field of big data,and point to the ethical dimension of the big data phenomenon.Findings:There still are serious problems to overcome before the field of big data can deliver on its promises.Implications and limitations:This contribution offers a personal view,focusing on the information science aspects,but much more can be said about software aspects.Originality/value:We express the hope that the information scientists,including librarians,will be able to play their full role within the knowledge discovery,data mining and big data communities,leading to exciting developments,the reduction of scientific bottlenecks and really innovative applications. | Ronald ROUSSEAU | 2012 | Chinese Journal of Library and Information Science2012，，3： | 13 |

| 13 | 新出现趋势识别和分析方法引介显示文摘新出现趋势是一个新研究论题深入研究并日趋重要的趋势。这种趋势在科学前沿形成,通过研究人员相互引用表现出来。检测这样的趋势所用的方法起源于引文分析。以前,引文分析仅仅是简单的静态的数量分析,而现在开始利用复杂网络分析和时间序列分析进行动态发展趋势预测。目前新出现趋势分析的方法主要有两种:一是从高引用文章组成的聚类串随时间推移的变化特征中检测出新出现趋势。二是在引文网络中所形成的研究社区中检测新出现趋势。目前新出现趋势分析还要在三个方面进行深入研究:一是要在实证研究充分开展的基础上,调查各个研究领域中新出现趋势的形成机制。二是要研究不同的时间序列对新出现趋势的识别和分析的影响。三是要研究新出现趋势对引文网络局部特征的影响。 | 刘玉仙 Ronald Rousseau | 2009 | 科学学研究2009，27，7： | 6 |
| 14 | Unnormalized and normalized forms of gefura measures in directed and undirected networks显示文摘In some networks nodes belong to predefined groups(e.g.,authors belong to institutions).Common network centrality measures do not take this structure into account.Gefura measures are designed as indicators of a node's brokerage role between such groups.They are defined as variants of betweenness centrality and consider to what extent a node belongs to shortest paths between nodes from different groups.In this article we make the following new contributions to their study:(1) We systematically study unnormalized gefura measures and show that,next to the ‘structural' normalization that has hitherto been applied,a ‘basic' normalization procedure is possible.While the former normalizes at the level of groups,the latter normalizes at the level of nodes.(2) Treating undirected networks as equivalent to symmetric directed networks,we expand the definition of gefura measures to the directed case.(3) It is shown how Brandes' algorithm for betweenness centrality can be adjusted to cover these cases. | Raf GUNS Ronald ROUSSEAU | 2015 | Frontiers of Information Technology & Electronic Engineering2015，16，4： | 6 |
| 15 | On indexing in the Web of Science and predicting journal impact factor显示文摘We discuss what document types account for the calculation of the journal impact factor (JIF) as published in the Journal Citation Reports (JCR). Based on a brief review of articles discussing how to predict JIFs and taking data differences between the Web of Science (WoS) and the JCR into account, we make our own predictions. Using data by cited-reference searching for Thomson Scientific's WoS, we predict 2007 impact factors (IFs) for several journals, such as Nature, Science, Learned Publishing and some Library and Information Sciences journals. Based on our colleagues' experiences we expect our predictions to be lower bounds for the official journal impact factors. We explain why it is useful to derive one's own journal impact factor. | Xiu-fang WU Qiang FU Ronald ROUSSEAU | 2008 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008，9，7： | 5 |
| 16 | Informetrics显示文摘A short history of informetric and bibliometric studies is provided and the role of the Belgian information and library scientist Paul Otlet is highlighted.The difference between the terms informetrics,bibliometrics and scientometrics is explained,following Ingwersen and Bjrneborn.A short overview of topics is given and some predictions related to the future of the field are made.It is the author's opinion that besides many practical applications,the field will also develop using axiomatic and algebraic(structural)approaches.The author has no doubt that China will become a leading country in the field. | Ronald Rousseau | 2009 | 图书情报工作2009，53，12： | 4 |
| 17 | Dynamics and interactions of blog-based science communication:A case study of blogging activities in China related to 2011 Japanese seismic and nuclear power crisis显示文摘Purpose:This paper tries to understand the dynamics of scientific communication systems during crises by investigating as a case study the blogging activities that took place during the period of the 2011 earthquake and related events in Japan.Interactions between bloggers and registered users are studied quantitatively and qualitatively at Sciencenet.cn,an influential science-related blogosphere in China.Design/methodology/approach:The editors of Sciencenet.cn compiled a special issue of science blog articles under the title Analysis of the Japanese Earthquake.We developed a spider program and downloaded from this special issue the metadata about title,content,publishing time,total read count,reply count and recommendation count,and further collected information about bloggers and recommenders.We then sent a short message to the bloggers who wrote articles on these emergencies,asking for their educational and professional background.Findings:We found that knowledge reflected in the blog articles is strongly related to the educational and professional background of bloggers.Knowledge diffusion is facilitated by interactions,such as recommendations,comments and answers.Interactions via comments and recommendations are of an assortative nature:A blog article is more likelyto be commented on and recommended by those bloggers who write on the same or similar topics than by those writing on a different one.Registered users tend to give comments on articles dealing with the topic that they recommend,and vice versa.Interaction in the intersection of two or three topics is more intense than that within one topic.The impact of blog articles is also influenced by other factors,such as the reputation of the blogger and the type of information they contain.Implications and limitations:It is confirmed that studying blogs is a valid approach within informetric studies.Yet,we only studied one triple(earthquake,tsunami,nuclear disaster)event based on data originating from one Chinese blog website.More events should be studied.Originality/value:Informetric studies based on blogs are still relatively few.Using science blogs and combining comments on a triple event with the knowledge background of bloggers in China is even less common.As such this contribution enhances our knowledge on this new form of science communication activity. | Yuxian LIU Li LIU Ronald ROUSSEAU Yang YANG | 2013 | Chinese Journal of Library and Information Science2013，，1： | 2 |
| 18 | The F-measure for Research Priority显示文摘Purpose: In this contribution we continue our investigations related to the activity index(AI) and its formal analogs. We try to replace the AI by an indicator which is better suited for policy applications.Design/methodology/approach: We point out that fluctuations in the value of the AI for a given country and domain are never the result of that country's policy with respect to that domain alone because there are exogenous factors at play. For this reason we introduce the F-measure. This F-measure is nothing but the harmonic mean of the country's share in the world's publication output in the given domain and the given domain's share in the country's publication output.Findings: The F-measure does not suffer from the problems the AI does.Research limitations: The indicator is not yet fully tested in real cases.R&D policy management: In policy considerations, the AI should better be replaced by the F-measure as this measure can better show the results of science policy measures(which the AI cannot as it depends on exogenous factors).Originality/value: We provide an original solution for a problem that is not fully realized by policy makers. | Ronald Rousseau | 2018 | Journal of Data and Information Science2018，3，1： | 2 |
