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