一项变革性研究如果遭遇延迟承认，如何寻找唤醒她的王子文献？ 根据我们前期的相关工作：①应用引文速率相关指标验证了 2014 年诺贝尔化学奖得主 Stefan W. Hell 的代表作（ Hell, 1994 ）是一篇典型的睡美人文献，初步提出结合被引速率和延迟承认指数，可较快识别出文献集合中的睡美人文献；②针对在睡美人文献的被引次数突增过程中起到关键促进作用的文献分析表明，在睡美人文献第一代施引文献的参考文献中，发表于睡美人文献引用突增年，同被引速率、共同延迟承认指数分别与睡美人文献的被引速率、延迟承认指数越接近，越有可能是王子文献 。 但上述关于王子文献的识别方法较繁琐，且透明度低，基于该科学发现是一项变革性研究（颠覆了 Ernst Abbe 的经典衍射极限理论）的特征，作者进而对识别方法进行简化，提出了一个适用于变革性研究的文献计量学框架，用于识别唤醒睡美人文献的王子文献：①发表于被引突增的附近年份；②本身被引次数较高；③与睡美人文献的同被引次数高；④在年度被引次数曲线上，王子文献对睡美人文献的“牵引或拉动”作用应非常显著，即至少在临近睡美人文献引用突增的年份，王子的年度被引次数应高于睡美人。作者也基于这四点标准尝试识别并分析了临床医学四大高声望期刊上发表的睡美人文献的王子文献 。 但,科学发现分不同类型，如托马斯•库恩根据范式不同将创新性研究分为渐进性创新和变革性创新，Science杂志前主编Koshland Jr将科学发现分为攻关型、挑战型和机遇型三类，作者通过进一步思考后认为，第四点并非普适于不同科学发现类型的睡美人文献，而仅适用于变革性创新或挑战型发现。由于变革性研究或超前于现有认知领域，或颠覆了已被公认或形成共识的理论，学术共同体或不知道其存在而忽视，或由于对此保持较大的心理距离而不相信其价值而抵制。王子文献出现后，才促使人们了解到睡美人文献的创新思想；有了王子文献率先施引或作为线索，才促使人们开始频频引用睡美人文献，或将王子文献和睡美人文献同时引用。当时，相比睡美人文献，人们对王子文献更熟悉，所以王子文献的年度被引次数应高于睡美人文献。案例研究显示，采用该框架识别出的王子文献与该领域科学史评论事实相一致。但上述框架仅从一个典型的变革性研究案例分析得出，是否广泛适用仍需进一步研究与实证检验。文章发表于 Journal of Data and Information Science。 见：Du, J., Wu, Y.S.

引文分析中，以被引次数作为测度指标，常常出现大量相同的被引次数（tie），例如，两篇论文都被引用了50次。我们认为， 不同级别学者施引的份量（权重）是不同的 。但当前引文分析中，统计被引次数时大牛的引用与新手的引用被视为等同，将不同级别学者的引用做几何累加。“被引次数”、“期刊影响因子”、“即年指标”、“ h 指数”等指标无不如此。为了合理地给不同的施引赋予不同的权重， 我们 改进 Google的PageRank算法，提出ArticleRank算法 。与“被引次数 ”这一指标相比， 该算法能有效地区分不同级别学者的引用，尤其适合测度高被引论文的学术影响力。 论文发表在Aslib Proceedings（SSCI收录），附论文标题与摘要： ArticleRank: a PageRank-based alternative to numbers of citations for analysing citation networks Abstract Purpose – The purpose of this paper is to suggest an alternative to the widely used Times Cited criterion for analysing citation networks. The approach involves taking account of the natures of the papers that cite a given paper, so as to differentiate between papers that attract the same number of citations. Design/methodology/approach – ArticleRank is an algorithm that has been derived from Google’s PageRank algorithm to measure the influence of journal articles. ArticleRank is applied to two datasets – a citation network based on an early paper on webometrics, and a self-citation network based on the 19 most cited papers in the Journal of Documentation – using citation data taken from the Web of Knowledge database. Findings – ArticleRank values provide a different ranking of a set of papers from that provided by the corresponding Times Cited values, and overcomes the inability of the latter to differentiate between papers with the same numbers of citations. The difference in rankings between Times Cited and ArticleRank is greatest for the most heavily cited articles in a dataset. Originality/value – This is a novel application of the PageRank algorithm. Keywords – Bibliographies, Reference services Paper type – Research paper
Alternative metrics, sometimes shortened to just altmetrics, is an umbrella term covering new ways of approaching, measuring and provideing evidence for impact. ——Euan Adie Alternative to what (替代什么）？ 替代计量中的“替代”部分，意指替代研究计量的传统视角，即仅使用引文来测度影响力。 但是这并不是说，要完全代替基于引文的计量指标。 Uptake of Altmetrics（替代计量的采用） Publishers and institutions have been quick to take to altme-trics of various forms, and many journal platforms support the provision of altmetrics in some form as standard; altme-tric.com alone serves some 4M requests for data a day, and some publishers like PLoS successfully run in-house altme-trics collection programmes. Interestingly one of the primary drivers of usage of altmetrics is authors looking at their own work, rather than other people’s. This makes sense: if you published a paper tomorrow, would you interested in who else might read or discuss it? Would you want to have some indication of whether or not it was getting more or less attention that you might expect? Partly this is, for lack of a better word, an ego thing. It’s natural as an author to want to know who has seen your work, who is reading it properly, commenting on it, citing it. In this context, however, egotism isn’t a negative character trait. Rather it’s something that you need to have developed to be a successful researcher –grants don’t go to people who can’t demonstrate that they’ve had any influence in their field. Practically speaking this means that the majority of acade-mic publishers using altmetrics do so as an author service, linking to altmetrics data reports from each article. Using the data for discovery is less popular amongst publis-hers, perhaps because of the more complicated integrations required for their platforms. That said several successful pilots have been run by Elsevier (showing articles that have been ta-lked about recently on journal homepages) and others. Altmetrics are also used in other areas: by institutions as an awareness tool, for research admin or for reputation mana-gement; by funders, looking for evidence to help show that grant funded research outputs are giving value for money and by mainstream media to pick up interesting stories be-fore they’ve been picked up in other media outlets. Challenges（替代计量面临的挑战） Before altmetrics can truly be considered mainstream there are several challenges to overcome. One is simply a common understanding of exactly what altmetrics are and how they should be used: the price of rapid progress in the field has been some confusion over exactly what is being claimed; about what’s hope and what’s hype and what circumstances the data is to be used in. Another is to get stakeholder communities involved in the further development of altmetrics tools and best practice. Up until now altmetrics has been driven by the people working in that field (and coming, generally, from academic re-search or publishing backgrounds). If altmetrics are to be truly useful to, for example, a small biomedical funder then we need small biomedical funders to be speaking up and talking about what the data they need is. Finally, data availability and reliability is critical. Citations have the benefit of being for the most part stable, captured in the scholarly record and clearly recorded, at least since the advent of CrossRef, Scopus and Web of science. The nature of altmetrics data is that it is much more transient and difficult to capture, at least in a way that allows for clear auditing and tracking data back to the source. 截选自Taking the alternative mainstream，里面也有涉及替代计量内涵的探讨，包括替代计量的快速发展造成的一些困扰。
Computer models for identifying instrumental citations in the biomedical literature Lawrence D. Fu Yindalon Aphinyanaphongs Constantin F. Aliferis Received: 28 November 2012 / Published online: 27 February 2013 Akade′miai Kiado′, Budapest, Hungary 2013 The most popular method for evaluating the quality of a scientific publication is citation count. This metric assumes that a citation is a positive indicator of the quality of the cited work. This assumption is not always true since citations serve many purposes. As a result, citation count is an indirect and imprecise measure of impact. If instrumental citations could be reliably distinguished from non-instrumental ones, this would readily improve the performance of existing citation-based metrics by excluding the non-instrumental citations. A citation was operationally defined as instrumental if either of the following was true: the hypothesis of the citing work was motivated by the cited work, or the citing work could not have been executed without the cited work. This work investigated the feasibility of developing computer models for automatically classifying citations as instrumental or non-instrumental. Instrumental citations were manually labeled, and machine learning models were trained on a combination of content and bibliometric features. The experimental results indicate that models based on content and bibliometric features are able to automatically classify instrumental citations with high predictivity (AUC = 0.86). Additional experiments using independent hold out data and prospective validation show that the models are generalizeable and can handle unseen cases. This work demonstrates that it is feasible to train computer models to automatically identify instrumental citations. 研究人员的引用地为非常复杂，有的是正面引用，有的是负面引用，有的是上用观点，有的是引用数据......这篇文章基于以下规则，然后建立语料库，通过构建模型让计算机进行学习，然后利用模型对论文的引用进行区分，进而把引文分为不同类型。 For the purposes of this study, a citation is operationally defined as instrumental if either of the following rules is true: 1. the hypothesis of the citing work is motivated by the cited work 2. the citing work could not have been executed without the cited work 还没细看细节，觉得这种方式不错，与大家分享。

近日，读到 JASIS （ 2010 年第一期的第一篇文章） Problems of Citation Analysis: A Study of Uncited and Seldom-Cited Influences ，对我的启发十分大，开始彻底颠覆我并不牢固的情报学基础认识，因此，我把我及时的感受写出来与大家分享，希望能够得到科学网前辈们的指点。 作者： M.H. MacRoberts and B.R. MacRoberts 全文： Problems of Citation Analysis: A Study of Uncited and Seldom-Cited Influences Problems of Citation Analysis: A Study of Uncited （论文下载仅作为学术用途） 一、 读文感受 文章提到了 引文分析的基础 ： Cole and Cole (1972) found that highly cited physics papers also cited highly cited papers, and so on. If we did not know that biogeographic papers cited very few of their influences, we might come to the same conclusion as the Coles: that only a small number of individuals contribute to scientific progress. But knowing that the vast majority of influence is not cited and that influence is not to be found in the Thomson Reuters-monitored journals leads to a different conclusion: that manynot a fewcontribute to scientific progress. Cole 在 1972 年发现 高被引的物理学论文同样也会应用高被引论文等等 如果我们不了解生物地理学论文引用很少的对文章产生巨大影响的文献，我们可能得出与 Cole 相同的结论：仅有少数的个体对于科学的进步是有贡献的。但是，如果我们知道大量有影响的内容不会被 SCI 所引证，也许会导致一个不同的结论：是许多个体 而不仅仅是少数人 对于科学的进展有贡献。 （一） 举了两个例子： 1. The latitudinal gradient of species-area relationships for vascular plants of North America. published in 2007 in American Naturalist 一文中引证了 A total of 1,742 floras of North America north of Mexico （ 1742 种植物群），而这些植物群的资料范围覆盖了政府文献、论文、未出版的报告、网页内容、短评以及 2000 多页的参考资料。这部分内容也被提及，出现在 Appendix A ，然而该论文仅引用了 85 篇文献，而这些被引文献仅仅是 SCI 文献，这些文献主要是用于解释物种的多样性的文章。 2. 作者本人发表了一篇 2 页的短文 Palhinhaea cernua (L.) Vasconcellos Franco (Lycopodiaceae) new to Texasin Phytologia ，该期刊不是 SCI 论文。这篇文章通过 SCI EXPANDED 和 GOOGLE SCHOLAR 检索均发现没有任何引证，然而，这篇文章确被整合进了德州和北美的植物地理文献中，该信息被广泛的应用；另外， USDA 植物数据库以及自然服务（ NATURESERVE ）数据库都将该文章的研究纳入进去。换言之，该论文即被印刷版也被电子版的出版物所引用，这篇文章的研究目的已经达到了。 上面两个例子证明了，被引文献仅仅只能代表有影响文献资料的一个片段。 （二） 作者同样做了一个小的定量实证：（哈哈！虽然作者认为定量分析并不是一种包打天下的方法） We selected 10 theoretical/analytical biogeographical articles that were published in journals that are monitored by Thomson Reuters and examined their bibliographies. These 10 articles are from the 22 described in this study. We recorded whether the cited item was (a) a article from a journal not monitored by Thomson Reuters, (b) an article from a Thomson Reuters-monitored journal, (c) a book or chapter in a book, (d) an unpublished report, (e) a thesis or dissertation, or (f) an online Web source or CD-ROM. There were 530 citations in these 10 articles. We selected five data articles or sources used for data in the 22 theoretical/analytical articles, such as those listed in McLaughlin (2007). We recorded the same information that we recorded for the other sample. We stopped when we reached 530 items so that the two samples would be equal. Table 1 shows the data for the two groups. Statistical comparison of the two groups shows that there is no possibility of them being derived from the same population. Theoretical/analytical biogeographical articles predominantly cite theoretical/analytical articles from Thomson Reuters-monitored journals; data articles do not cite many Thomson Reuters-monitored articles but instead cite work from journals not monitored by Thomson Reuters, unpublished reports, theses/dissertations, and the grey literature. 对于两个群体的统计比较显示：理论或者分析类的植物地理文献主要引用了 SCI 的理论和分析文献；而数据类型的文献则没有引用太多的 SCI 文献，相反，他们主要引用的是非 SCI 文献、未发表的报告、研究论文，或者是灰色文献。 er二、反思 这篇文献对我的震撼是极大的。 主要有二点： （一） 以引文为基础的方法是不是对于所有学科的评价都有价值，是值得反思的。其实，自然科学中，除了植物地理学以外，很多学科的研究都包含了对于原始数据和基础理论分析的研究，而我们现在评价体系的一个重要指标 引文则是对于数据研究这部分内容的价值忽略了的。 （二） 文献计量学中 Cole 的理论：仅有少数的个体对于科学的进步是有贡献的 或者还应该包括 洛特卡定律 这些理论都从 分析方法（仅仅考虑第一作者） + 分析框架（仅仅展示核心作者） + 分析目的（评价作者贡献） 是出于一种狭隘、自私的学术观点。但是，如果我们反思 真的是只有小部分人对于科学的进步有贡献吗？ 真的是一将功成万骨枯吗？ 。这是我们图书情报学界急需要考虑的问题。 中国的情报学目前还从创作过自己有价值的理论，但研究中确充斥着各式各样标榜自己学术地位的所谓学科知识地图，这有时是一种讽刺。
A comprehensive discussion on the use of citation analysis to rate scientific performance and the controversy surrounding it. The general adverse criticism that citation counts include an excessive number of negative citations (citations to incorrect results worthy of attack), self-citations (citations to the works of the citing authors), and citations to methodological papers is analyzed. Included are a discussion of measurement problems such as counting citations for multiauthored papers, distinguishing between more than one person with the same last name (homographs), and what it is that citation analysis actually measures. It is concluded that as the scientific enterprise becomes larger and more complex, and its role in society more critical, it will become more difficult, expensive and necessary to evaluate and identify the largest contributors. When properly used, citation analysis can introduce a useful measure of objectivity into the evaluation process at relatively low financial cost.
Publish or Perish，在美国七十年代初期兴起，并在国际上流行，意思是(论文)不发表就会被埋没，发表还是灭亡，发表或消亡。 Harzing, A.W把自己设计的一款检索和分析学术引文的免费小软件叫做Publish or Perish( http://www.harzing.com/pop.htm )。目前有上百个博客和图书馆网站、还有报纸和杂志对其进行了报导；也有多篇论文以该软件作为数据收集和分析的工具。在宣称这个软件具有的评价个人或机构学术影响力的同时，作者也总结了应用局限。 软件的主要特色有三：一是 软件相当小巧，也十分简单易操作，仅有384K，有Windows和Linux多个版本。 它使用的原始引文数据来自于Google Scholar，适合进行网络引文的分析。作者在其博客中提到，希望看到软件结果与WoS分析出的结果的比较研究，这可能是对传统引文与网络引文对比研究的好题材。 软件可以得出多个最新的引文分析评价指标，如Total number of papers 、Total number of citations 、Average number of citations per paper 、Average number of citations per author、Average number of papers per author 、Average number of citations per year 、Hirsch's h-index and related parameters 、Egghe's g-index 、The contemporary h-index 、The age-weighted citation rate 、Two variations of individual h-indices 、An analysis of the number of authors per paper.
几乎是与 Moravcsik 同一时期，康奈尔大学的 Daryl E. Chubin 和Soumyo D. Moitra 也设计和应用了一个根据引用情况对引文进行分类的系统，与Moravcsik的引文分类略有不同，他们的研究包括：（1）重新细化了Moravcsik的分类体系，使类目间相互排斥；（2）从4种实验和理论物理学领域的期刊中抽取论文，然后用修改过的分类体系对这些论文进行分类。（3）将《科学引文索引》的计数与从我们引文分布中不同类别的引文中抽取出来的样本进行比较。发现正式的论文中95%的引文是肯定性的，这算做是对引文计数活动的初步支持。但是作者还是强调：首先，无论是对来源文献还是被引文我们都不应该只根据数字评价其价值，论文被引次数上的变异不过是给形形色色的正式交流的动机和标准提供了证据。其次，作者认为科学界是按照年龄和威望分成等级的，这种等级划分又都控制在具有很高的学术共识的学科之内，在高能物理学界，大家绝对不会同等地理解和实施引用文献的规矩的。最后，作者认为应该重建学科知识史（类似今天说的知识图谱），包括研究期间的统计，例如专业数目，文献的分布，设备的使用等等情况。只有这样才能了解到专业的变化，这样一来，不仅仅研究者发表论文的情景，而且可能他们引用某篇著作的原因也可以了解了；也只有到那时，我们才可以充分利用引文计数，也充分使用让引文计数有效的其他测量指标了。 【这篇文章提供给我们一个线索，也许可以把知识图谱和引文情景结合起来，让引文分析的研究重新焕发青春】 D.

最近一期《 Scientometrics 》公告了两年一次的科学计量学最高奖项 Derek John de Solla Price Medal结果。获奖人为匈牙利的 Peter Vinkler 和法国的 Michel Zitt。 两位早年分别是化学家和管理学者，近年在引文分析和评价方法与指标等热点问题上颇有建树。 笔者对两位的直接印象是：Vinkler也参与了目前h指数研究热潮，而Zitt的逻辑化推理能力很强。 另外， Glanzel 指出，Vinkler是位独狼，为啥呢？刚查了一下，他80年代进入这一领域至今，在LIS学科内发表了30余篇文章，全是独著！ 希望早日见到我国科学计量学家获得这一荣誉。 参考文献： Pter Vinkler and Michel Zitt win the 2009 Derek John de Solla Price Medal.

科技大国中，美国可能是传统同行评议最坚定的维护者，在欧亚各国近年普遍引入被人痛恨的量化评价背景下，一直动作很小。 当然估计这只是一个参考。 但这是一个开始吗？ ------------------------------------------------------------------------------------------------------- "Philadelphia, PA, London, UK, August 3, 2009 – Thomson Reuters with Discovery Logic, Inc. today announced that the National Institutes of Health (NIH) has chosen Web of Science data to power the NIH electronic Scientific Portfolio Assistant (eSPA). eSPA is an information technology system designed to assist NIH grants management officials in creating grant portfolios and tracking research outputs and outcomes, including publications and citations."

《 Nature 》和《 Science 》哪个影响力更大？ 半个世纪的 h 指数视角浅析 《 Nature 》和《 Science 》可能是现有最具影响力的综合类科技期刊。国人在上面发表论文，很多所在单位也会给予几十万甚至上百万的重奖，可谓名利双收。 但关于《 Nature 》和《 Science 》哪个更好一直存在很大争议。这里以两种期刊在 Web of Science 中 5 年等距抽样 h 指数（含义见注释 1 ）数据，粗略探讨过去半个世纪以来，《 Nature 》和《 Science 》的影响力演进实况和相互差别。 统计时段选择 1955 年－ 2005 年。未选择更早的数据，是因为 Web of Science 1955 年之前的数据只能按较长时段查询不能按具体年份检索。另外，据笔者所知，此两种期刊在世界范围的权威地位于 20 世纪下半叶才逐渐完全确立。 图 1 是两种期刊的 h 指数演变数据。 图 1 1955 年－ 2005 年《 Nature 》和《 Science 》的 h 指数演变及比较 可见， 20 世纪下半叶，《 Nature 》和《 Science 》的 h 指数一直在上升，特别是 1975 年后，两种期刊的影响力扩大很快。两种期刊的 h 指数峰值都在 1995 年，当年两种期刊各有 280 余篇论文至今被引用了不少于 280 余次，论文影响力持续能力较强。新世纪里 h 指数的下降并不能证明两种期刊影响力有所下降，而是 h 指数增长需要时间积累所致。 半个世纪以来，除了 1965 年两种期刊 h 指数相等外，其余统计点上，《 Nature 》的 h 指数都大于《 Science 》，这种差别在 1980 年－ 1990 年之间较为明显，但近年来差距似乎有所缩小。 h 指数主要关注产出论文集合的高被引论文及其被引强度 。应指出的是，任一单一指标的测度总有片面性，本博文数据仅供参考。 注释： 1. h 指数由美国物理学家 Hirsch 于 2005 年提出，以简单的计算同时衡量学者个人论文成果的数量和质量（影响力） 。 Braun 将其扩展到对期刊的 影响力测评 。 期刊 h 指数的定义为：某一时段内，期刊发表的总计 N 篇论文中，有 h 篇论文的被引次数至少为 h 次，且其余 N-h 篇论文的被引次数均小于或等于 h 。期刊 h 指数是目前除学者 h 指数之外，研究和应用最多的 h 指数扩展。 参考文献： 赵星 , 高小强 , 何培 . 科学基金 h 指数 : 基金论文成果数量与影响力的综合衡量 . 中国科学基金 ,2009,1: 15-19 Hirsch J E.

引用他人论文的动机很多，但你是否想过，你引用他的文章，可能有时仅仅因为是喜欢他而已？ 读到最新一期《Research Trends》的Pleased to cite you: the social side of citations一文，其中观点有新有旧。这里仅探讨一点：人们的引用是否有时候只是因为喜欢？ 只要理性上还遵从科学原则，理论上引文网络就不会和社会网络完全重叠。但部分交织恐怕是不可避免。 回头去看你的大作，是否引用了很多导师、同门、同事、朋友又或学科大牛、学术偶像的文章呢？是否每篇都必要呢？为什么同为可有可无的引用，你引用了他而不是陌生人呢？ 也许你觉得这是各种潜规则所致。其实有时也不然，你引用他，可能只因你喜欢他。你喜欢他，因此信任他，然后引用他，仅此而已。 引用有时只是认同，认同的不是某个观点，而是那个人。 这也解释了，为何很多人爱自引？因为，多数人最爱的，还是自己。
