An information need can be modeled by a binary classifier such as support
vector machine (SVM). SVMs can exhibit very conservative precision
oriented behavior when modeling information needs. This conservative
behavior can be overcome by adjusting the position of the hyperplane, the
geometric representation of a SVM. The present invention describes a
couple of automatic techniques for adjusting the position of an SVM model
based upon a beta-gamma thresholding procedure, cross fold validation and
retrofitting. This adjustment technique can also be applied to other
types of learning strategies.
