The intention of this work is to analyze top scientists' collaboration behavior at the "international", "domestic extramural" and "intramural" levels, and compare it to that of their lesser performing colleagues. The field of observation consists of the entire faculty of the Italian academic system, and so the coauthorship of scientific publication...

Social network analysis is playing an increasingly important role in sociological studies. At the same time, new technologies such as wearable sensors make it possible to collect new types of social network data. We employed RFID tags to capture face-to-face interactions of participants of two consecutive Ph.D. retreats of a graduate school on clim...

As a driver in modern science, interdisciplinary research has attracted a lot of attention. Major foci are laid on exploring the relations of multiple involved disciplines as well as the knowledge structure in interdisciplinary field. However, there is still a lack of decomposing the knowledge structure of interdisciplinary field to investigate how...

The challenge of increasing the impact of regional journals has received much attention. While funding and research agencies require the acceptance of papers from foreign authors as a means of increasing citations, Brazilian journal editors dispute the impact of this measure. This study aimed to evaluate, for Brazilian medical journals, whether the...

Collaboration among researchers plays an important role in scientific discoveries, especially in multidisciplinary research. How to allocate credit reasonably to coauthors of a paper is a long-standing problem in the science of sciences. The collective credit allocation method (CCA method) proposed by Shen, H. W. and Barabási, A. L. provides a nove...

Fragmented or multiple publishing is generally considered negative, as authors may inflate their number of articles through duplicate publications and salami publications. However, there are valid and defensible arguments for a single research study generating multiple publications. The existing literature confirm the existence of fragmented publis...

Understanding communications across disciplines is critical to the promotion of interdisciplinary innovation. Using research into the psychological concept of joint attention (JA) as an example of shared interest, this paper focuses on studies of JA across three different domains (child psychology, robotics, and human–computer interaction) and anal...

Collaboration recommendation from scholarly big data is an important but challenging problem as it might suffer the difficulty of accurate recommendation from three aspects: how to efficiently integrate the available author-related information, how to precisely describe the characteristics of the scholarly data samples, and how to extract the intri...

The development of a scientific discipline is partly determined by the growth of its literature. Bibliometrics constitute a set of mathematical and statistical techniques employed to explore, organize, and quantitatively analyze large pools of scientific literature. In this study, 11,433 papers published between 1974 and 2015 are collected and anal...

We propose the I3* indicator as a non-parametric alternative to the journal impact factor (JIF) and h-index. We apply I3* to more than 10,000 journals. The results can be compared with other journal metrics. I3* is a promising variant within the general scheme of non-parametric I3 indicators introduced previously: I3* provides a single metric which...
