The impact factor has been extensively used in the last years to assess journals visibility and prestige. While it is useful to compare journals, the specificities of subfields visibility in journals are overlooked whenever visibility is measured only at the journal level. In this paper, we analyze the subfields visibility in a subset of over 450,000 Physics papers. We show that the visibility of subfields is not regular in the considered dataset. In particular years, the variability in…

A comparative analysis of local similarity metrics and machine learning approaches: application to link prediction in author citation networks

This study compared the performance of 10 well-known local network similarity measurements with four machine learning models to predict future links in author citations networks and revealed that the Jaccard coefficient was found to be among the most relevant measurements.

A comparative analysis of local network similarity measurements: application to author citation networks

This study compared the performance of 10 well-known local network similarity measurements to predict future links in author citations networks and found that a neural network approach summarizing the information from all 10 considered similarity measurements was not able to provide the highest prediction performance.

Recency predicts bursts in the evolution of author citations

A systematic study of the evolution of author citations, and in particular their bursty dynamics, is conducted and empirical evidence of a correlation between the number of citations most recently accrued by an author and the number they receive in the future is found.

Practical method to reclassify Web of Science articles into unique subject categories and broad disciplines

This work presents an easily reproducible method to perform reclassification of the Web of Science into existing subject categories and into 14 broad areas, which preserves disciplinary differences that may exist among individual articles published in the same journal.

Impact factor volatility due to a single paper: A comprehensive analysis

It is found that IFs are highly volatile and that small journals are rewarded much more strongly than large journals for a highly cited paper, while they are penalized more for a low-cited paper, especially if their IF is high.

Forma mentis networks quantify crucial differences in STEM perception between students and experts

Cross-validation with external datasets indicated that the negative emotional auras of physics, maths and statistics in the students’ forma mentis network related to science anxiety, underline the crucial importance of emphasizing nontechnical and applied aspects of STEM disciplines, beyond purely methodological teaching.
