statistics; keyword co-occurrence network

We collect metadata including published year and keywords for 84,725 papers published in 42 statistical journals from 1992 to 2021 from the Web of Science (www.webofscience.com). After combining different expressions of the same keyword and filtering out keywords with low frequency, we finally obtain 5,037 keywords. Multiple keywords co-exist within a paper, and this co-occurrence relationship can be utilized to construct the keyword co-occurrence network.
