Self Citation analysis on PubMed data

DOI

Code for reproducing the experiments, figures, and tables presented in the paper Mishra, S., Fegley, B. D., Diesner, J., & Torvik, V. I. (2018). Self-Citation is the Hallmark of Productive Authors, of Any Gender. PLoS One.

Data

Our experiments relied on data from multiple sources including properitery data from Thompson Rueter's (now Clarivate Analytics) Web of Science collection of MEDLINE citations. Author's interested in reproducing our experiments should personally request from Clarivate Analytics for this data. However, we do make a similar but open dataset based on citations from PubMed Central which can be utilized to get similar results to those reported in our analysis. Furthermore, we have also freely shared our datasets which can be used along with the citation datasets from Clarivate Analytics, to re-create the datased used in our experiments. These datasets are listed below. If you wish to use any of those datasets please make sure you cite both the dataset as well as the paper introducing the dataset.
