Judit Bar-Ilan (Hebrew: יהודית בר-אילן, 1958–2019) was an Israeli computer scientist known for her research in informetrics and scientometrics.
[3] Bar-Ilan did important work early in her career in the fault tolerance of distributed computing,[1] and her dissertation research was in cryptography.
Her interest in these topics stemmed from her work in the early 1990s on applications of distributed computing in library science.
Later in her career, her interests shifted to scientometrics, including citation analysis and studies of the h-index as well as altmetrics for measuring scholarly productivity.
[2][6] A special memorial issue dedicated to Judit Bar-Ilan was published in the journal Scientometrics in June 2020.
