IMPROVING CAUSE DETECTION SYSTEMS WITH ACTIVE LEARNING
ISAAC PERSING AND VINCENT NG

Abstract. Active learning has been successfully applied to many natural language processing
tasks for obtaining annotated data in a cost-effective manner. We propose several extensions to an
active learner that adopts the margin-based uncertainty sampling framework. Experimental results
on a cause detection problem involving the classification of aviation safety reports demonstrate
the effectiveness of our extensions.
