TL;DR: A complete database for the scientific specialty of research about “steel structures” shows that betweenness centrality of an existing node is a significantly better predictor of preferential attachment by new entrants than degree or closeness centrality.

TL;DR: In this article, a new size-independent indicator of scientific journal prestige, the SJR2 indicator, is pro- posed, which takes into account not only the prestige of the citing scientific journal but also its closeness to the cited journal using the cosine of the angle between the vec- tors of the two journals' cocitation profiles.

TL;DR: Besides being associated with quality, citation counts are correlated with the citation performance of the cited references, the language of the publishing journal, the chemical subfield, and the reputation of the authors.

TL;DR: In this paper, the authors of less than 4% of all publications intentionally chose to list their names alphabetically and the use of alphabetical authorship is most common in mathematics, economics, and high energy physics.

TL;DR: In this article, the authors developed interactive overlays to a global map of science based on aggregated citation relations among the 9162 journals contained in the Science Citation Index (SCI) and Social Science Citation index (SciCEI) 2009.

TL;DR: There are strong arguments in favour of using fractionalised counts to calculate relative citation indexes at the national level, rather than using whole counts, which is the most common practice today.

TL;DR: A statistical method aimed at estimating the effectiveness of numerical indicators in the suppression of citation biases and the fairness of fractional citation count, which has been recently proposed as a tool for cross-discipline comparison is presented.

TL;DR: In this article, the authors compare the effectiveness of different methods of normalizing citations, in order to provide useful indications to research assessment practitioners, and find that the citations average is the most effective scaling parameter, when the average is based only on the publications actually cited.

TL;DR: This study defines a couple of PageRank modifications that weigh citations between authors differently based on the information from the co-authorship graph and finds the new time-aware methods to outperform standard PageRank and its time-unaware weighted variants.

TL;DR: The purpose of this article is to come up with a valid categorization and to examine the performance and properties of a wide range of h-type indices presented recently in the relevant literature.

TL;DR: In this paper, the authors introduce a novel approach of analyzing distance-dependent probabilities of collaboration and reveal that intra-country collaboration is about 10-50 times more likely to occur than international collaboration.

TL;DR: In this paper, a method is proposed to monitor and record scientists' working timetable, and different working time patterns are revealed, such as overnight work is more prevalent among scientists, while Chinese scientists mostly have busy weekends with their scientific research.

TL;DR: Evidence is found to support the assumption that IR communities and topics are interwoven and co-evolving, and topics can be used to understand the dynamics of community structures, and the use of the hybrid approach to study the dynamic interactions of topics and communities is recommended.

TL;DR: It is found that referee behavior drastically affects peer review and an equal distribution of the reviewing effort is beneficial only if the scientific community is homogeneous and referee reliability is the rule.

TL;DR: This study will measure the dispersion of research performance within and between universities in the Italian university system, typically non-competitive, and investigate the level of correlation that occurs between performance in research and its dispersion in universities.

TL;DR: This study developed a classification for the pharmaceutical companies to divide them into four types, and provided some suggestions to them that have positive influences upon corporate performance.

TL;DR: In this article, the authors show that three factors can account for the referencing pattern of citation networks for two topics, namely "graphenes" and "complex networks", thus allowing one to reproduce the topological features of the networks built with papers being the nodes and the edges established by citations.

TL;DR: Overall, this article suggests that the degree of collaboration and the revised collaborative coefficient are superior measures that can be applied to bibliometric studies for future researchers.

TL;DR: Social media have a role of their own, complementing that of scientific journals, and their active use indicates the clear demand for them, and attention economy presents a fruitful viewpoint for studying scientific communication.

TL;DR: The effect of two different calculation methods for obtainingrelative impact indicators is modelled and the acronym “BMV” is suggested to term the relative impact indicators (e.g. RCR, CPP/JCSm, C PP/FCSm and RW) in scientometrics.

TL;DR: The leaders of scientific groups appear in the last place (or in the first place) of the authors’ lists of multi-author papers more often than other scientists (group-members).

TL;DR: It is found that author bibliographic coupling analysis (ABCA) has the advantage that it not only can discover the intellectual structure of a discipline more comprehensively and concretely but also can reflect the research frontier of the discipline.

TL;DR: A sequence-based perspective on scientific collaboration is proposed and it is shown that the productivity and influence approximately follow the power law for frequent sequences in the four levels of analysis.

TL;DR: The estimate results show that the diffusion of crisis information in micro blogs can be described by Logistic function, and the growth curve of NMCI is S-shaped.

TL;DR: The findings suggest that both papers and patents are geographically concentrated on a small number of countries, including the United States, the United Kingdom, Japan, Germany, and France.

TL;DR: Two core problems with the journal impact factor are discussed: first, citations of documents are generally not normally distributed, and, furthermore, the distribution is affected by outliers, which has serious consequences for the use of the mean value in the JIF calculation.

TL;DR: A modification of the h-index for multi-authored papers with contribution based author name ranking is introduced, denoted by hmc-index, which uses combined credit allocation (CCA) to replace fractionalized counting in the hm-index.

TL;DR: Two models to detect communities by considering both topic and dynamic features are proposed, which allow us to better understand the dynamic features of social networks and make improved personalized recommendations.

TL;DR: Overall, it seems that large-scale quantitative web research is possible with the Bing Search API 2.0, including query splitting, but that legal issues require the redesign of webometric software to ensure that all results obtained from Bing are displayed directly to the user.
