Academic co-word network link prediction dataset

Using the Web of Science core collection as the source of literature data. Five disciplines with different data scales were randomly selected from the Web of Science core collection discipline category catalog, namely Information Science&Library Science (ISLS), Law (LAW), Biomedical Social Sciences (BSS), Communication (COM), and Oceanography (Ocean). When conducting literature search, the "WC=subject name" search method is used to restrict the publication year to 2015, 2016, 2017, 2018, 2019, and 2020. Use the literature from 2015 to 2018 as the training stage for each co word network, and use the literature from 2019 to 2020 as the testing stage N2. On this basis, the extraction of keywords in the training and testing stages is carried out separately. The keywords that appear in both the training and testing stages need to be selected as nodes for building a co word network. Therefore, the intersection of the keyword sets in the training and testing stages is further processed to obtain the necessary keyword information for building a co word network for each discipline; After experimental analysis, keyword frequencies greater than 4, 6, 8, 10, 12, and 14 were extracted to construct a co word network with different topological structure features.
