The score-distributional threshold optimization for adaptive binary classification tasks
Avi Arampatzis, André van Hameran · 2001
The thresholding of document scores has proved critical for the effectiveness of classification tasks. We review the most important approaches to thresholding, and introduce thescore-distributional (S-D) threshold optimizationmethod. The method is based on score distributions and is capable of optimizing any effectiveness measure defined in terms of the traditional contingency table.
