Verb Subcategorization III
Brent’s system does well at precision, but not well at recall.
(Manning, 93)’s system addresses this problem by using a tagger and running the cue detection on the output of the tagger.
Manning’s method can learn a large number of subcategorization frames, even those that have only low-reliability cues.
Manning’s results are still low and one way to improve them is to use prior knowledge.
