The entity relationship diagram of SciSciNet. SciSciNet includes “SciSciNet_Papers” as the main data table, with linkages to other tables capturing data from a range of sources. For clarity, here we show a subset of the tables (see Data Records section for a more comprehensive view of the tables). PK represents primary key, and FK represents foreign key.
