Elements of NIH ExPORTER database used to connect to PubMed and evaluate precision and recall of Author-ity IDs.
Fig 2.
Three-step evaluation process.
Matching bibliographies of NIH ExPORTER to PubMed involves the connection of three data tables (NIH Projects, NIH Links, PubMed) across three databases (NIH ExPORTER, PubMed, Author-ity).

(A) Precision and (B) recall calculations.
A: Precision calculated by dividing the number of PMIDs in set M1 by the number of PMIDs in set A. B: Recall obtained by dividing the number of PMIDs in set S1 by the number of PMIDs in set B.
