Gemini-RxNorm performance at different match score levels. This chart displays the performance metrics of GEMINI-RxNorm when run using different “minimum match scores.” The match score is a number between 0 and 100 that RxNorm uses to indicate how closely a free-text string matches an RxNorm concept. The x-axis in this chart represents the minimum match score needed for GEMINI-RxNorm to return the match. The y-axis represents the percentage metrics of F-measure (F1-score), precision, and recall obtained by comparing the pharmacy orders returned by GEMINI-RxNorm to the 1 948 817 gold standard manually mapped pharmacy orders.
