| 1. An automated method of classifying input text according to a target classification system having two or more target classes,
the method comprising:
for each target class, determining a composite score based on a first score scaled by a first class-specific weight for the
target class and a second score scaled by a second class-specific weight for the target class, with the first and second scores
based on an input text and text associated with the target class; and
for each target class, classifying or recommending classification of the input text to the target class based on the composite
score and a class-specific decision threshold for the target class.
