Research into the automatic acquisition of subcategorization frames from corpora is starting to produce large-scale computational lexicons which include valuable frequency information. However, the accuracy of the resulting lexicons shows room for improvement. One source of error lies in the lack of accurate back-off estimates for subcategorization frames, delimiting the performance of statistical techniques frequently employed in verbal acquisition. In this paper, we propose a method of obtaining more accurate, semantically motivated back-off estimates, demonstrate how these estimates can be used to improve the learning of subcategorization frames, and discuss using the method to benefit large-scale lexical acquisition.
