Properties

Name Type Description

Name	Type	Description
F1Score	System.Double	Gets and sets the property F1Score. A measure of how accurate the recognizer results are for the test data. It is derived from the `Precision` and `Recall` values. The `F1Score` is the harmonic average of the two scores. For plain text entity recognizer models, the range is 0 to 100, where 100 is the best score. For PDF/Word entity recognizer models, the range is 0 to 1, where 1 is the best score.
Precision	System.Double	Gets and sets the property Precision. A measure of the usefulness of the recognizer results in the test data. High precision means that the recognizer returned substantially more relevant results than irrelevant ones.
Recall	System.Double	Gets and sets the property Recall. A measure of how complete the recognizer results are for the test data. High recall means that the recognizer returned most of the relevant results.
