It does not shy away from profound historical reflections, the attempt at a general overview, and it is satisfyingly broad when it comes to showing the range of areas in which bibliometrics. The web enables new ways to measure scholarly productivity and impact, making available tools and data that can reveal patterns of intellectual activity and impact that were previously invisible: mentions, acknowledgments, endorsements, downloads, recommendations, blog posts, tweets. The proportion of the 28 journals providing Web-only supplementary material increased from 32% 2003 to 50% 2005 to 61% 2007 to 64% 2009 , and the percentage of articles that contained supplementary material increased from 7% to 14% to 20% to 25%, respectively. Go to our Resources and Help section for instructions on. An important source of altmetrics is Twitter, which is a popular microblogging service. In this paper, the altmetric scores of top-cited altmetric papers are presented.
A meta-analysis across more than 40 cross-metric validation studies shows overall a weak correlation ranging from 0. Sugimoto, Mike Thelwall, Daril Vilhena, Jevin West, Paul Wouters. Citation counts tend to follow a discrete lognormal distribution and, in the absence of alternatives, have been investigated with negative binomial regression. In over 400 pages and 21 chapters it covers an array of issues stretching from the history of the field, ethical issues, development of new alt metric methods to descriptions of advanced methodologies for mapping and evaluating research. Citation represents a fee paid through transfer of some of the attention earned by the citing author to the cited author. Altmetrics researchers and practitioners have amassed a growing body of literature and working tools to gather and analyze altmetrics and there is growing interest in this emerging subfield of scientometrics. A comprehensive discussion on the use of citation analysis to rate scientific performance and the controversy surrounding it.
The difference between the mean ages may characterize thesynchronity of the author's research in comparison with those working on similar topics. The collaboration networks between authors and institutions reveal a homogenous community formed by the most prolific contributors. The area has great potential, but it needs more reflection, in-depth analysis and discussion about its theoretical foundations. Once the domain of information scientists and mathematicians, bibliometrics is now a fast-growing, multidisciplinary field that ranges from webometrics to scientometrics to influmetrics. With a focus on the social sciences, this article contributes to the existing literature on indicators and metrics use in fields with diverse publication practices. Article-level metrics followed by Altmetrics, i.
. We studied the spread of interest in news stories submitted to Digg in June 2006. Top-cited articles can be predicted from top-tweeted articles with 93% specificity and 75% sensitivity. We observed a marked increase in the number of video supplements. ContributorsMayur Amin, Judit Bar-Ilan, Johann Bauer, Lutz Bornmann, Benjamin F.
The transformation seems to originate from a growing interest in bibliometric topics. What we now need from this book's expert group is an accessible working narrative to guide the rest of us in our day jobs. The present study investigates the usefulness of altmetrics for measuring the broader impact of research. An analysis of online syllabus citations to 70,700 articles published in 2003 in the journals of 12 subjects indicates that online syllabus citations were sufficiently numerous to be a useful impact indictor in some social sciences, including political science and information and library science, but not in others, nor in any sciences. First, we provide an overview of the altmetrics landscape, comparing tool features, social media data sources, and social media events provided by altmetric aggregators. Based on the definition of the well-known h index we propose a t factor for measuring the impact of publications and other entities on Twitter.
The indicators compare the proportion of mentioned papers e. Bibliometrics has moved well beyond the mere tracking of bibliographic citations. It is argued that all of these form a role unique to the Web, albeit in varying degrees. Methods: This study is essentially based on a dataset with papers obtained from F1000. It publishes peer reviewed articles online in an open access format.
The article examines whether scientific production, research funding, Impact Factor of journals and size of collaborative teams have an influence on the propensity to receive more citations, and whether the influence of these factors differs across genders. However, the altmetric events differ from each other in terms of a small number of factors; for instance, institution prestige and country prestige associate with increased Mendeley readers and blog and news posts, but it is an insignificant factor for Twitter and Facebook posts. For me this book gives an overview of the whole field of bibliometrics, its origins and achievements. On the basis of investigating author's opinion on citing motivations of chemistry papers aquasi-quantitative model for citing is suggested. The literature is discussed in relation to the possible use of altmetrics in research evaluation.
As a result, evaluative citation analysis should take uncited work into account. This may now be changing. I argue that citations, while useful, miss many important kinds of impacts, and that the increasing scholarly use of online tools like Mendeley, Twitter, and blogs may allow us to measure these hidden impacts. A majority of respondents frequently used Wikipedia for background information, but less often than they used other common resources, such as course readings and Google. This opening article focuses on how and why two human resource development journals have expanded their social media activities. Also, we compare the overview offered by this range of indicators when applied to monographs with the traditional bibliometric perspective focused on journal articles and citation impact. Books, on the other hand, are quite often tweeted while both Mendeley's and the novel data source Library Thing's coverage is low.
The meat of Beyond Bibliometrics is satisfyingly rich with practitioner knowledge. Sugimoto, Mike Thelwall, Daril Vilhena, Jevin West, Paul Wouters. In this research, we propose a method to trace scientists' research trends realtimely. More than five years after their emergence, altmetrics are still seen as a promise to complement traditional citation-based indicators. What we now need from this book's expert group is an accessible working narrative to guide the rest of us in our day jobs. Editors should ensure that authors take relevant criticism seriously and respond adequately to it. Once the domain of information scientists and mathematicians, bibliometrics is now a fast-growing, multidisciplinary field that ranges from webometrics to scientometrics to influmetrics.
