This paper studies the problem of constructing an effective
heterogeneous ensemble classifier for text classification.
One major challenge of this problem is to formulate
a good combination function, which combines the decisions
of the individual classifiers in the ensemble. We
show that the classification performance is affected by three
weight components and they should be included in deriving
an effective combination function. They are: (1) Global
effectiveness, which measures the effectiveness of a member
classifier in classifying a set of unseen documents; (2)
Local effectiveness, which measures the effectiveness of a
member classifier in classifying the particular domain of
an unseen document; and (3) Decision confidence, which
describes how confident a classifier is when making a decision
when classifying a specific unseen document. We propose
a new balanced combination function, called Dynamic
Classifier Weighting (DCW), that incorporates the afore-mentioned
three components. The empirical study demonstrates
that the new combination function is highly effective
for text classification.
