Fig. 2From: Development of a novel drug information provision system for Kampo medicine using natural language processing technologyReceiver operating characteristic (ROC) curve using the threshold of confidence rate The best threshold of confidence rate was 61% according to the ROC curve. Precision, recall, and F-measure at the threshold were 0.986, 0.915, and 0.949, respectively. The developed system showed high performance with a precision, recall, and F-measure of approximately 0.9Back to article page
