WebSep 11, 2024 · F1-score when precision = 0.8 and recall varies from 0.01 to 1.0. Image by Author. The top score with inputs (0.8, 1.0) is 0.89. The rising curve shape is similar as Recall value rises. At maximum of Precision = 1.0, it achieves a value of about 0.1 (or 0.09) higher than the smaller value (0.89 vs 0.8).

This might occur in cases in which the gold standard contains a document without any annotations and the annotator (correctly) returns no annotations.
WebMar 8, 2024 · F1-score: F1 score also known as balanced F-score or F-measure. It's the harmonic mean of the precision and recall. F1 Score is helpful when you want to seek a balance between Precision and Recall. The closer to 1.00, the better. An F1 score reaches its best value at 1.00 and worst score at 0.00. It tells you how precise your classifier is.
