Acquiring German Prepositional Subcategorization Frames from Corpora.
Erika F. de Lima · 1997
This paper presents a procedure to automatically learn German prepositional subcategorization frames from text corpora. It is based on shallow parsing techniques employed to identify high-accuracy cues for prepositional frames, the EM algorithm to solve the PP attachment problem implicit in the task, and a method to rank the evidence for subcategorization provided by the collected data.
