Hybrid Disambiguation of Prepositional Phrase Attachment and Interpretation
Sven Hartrumpf · 1999
In this paper, a hybrid disambiguation method for the prepositional phrase (PP) attachment and interpretation problem is presented. 1 The data needed, semantic PP interpretation rules and an annotated corpus, is described first. Then the three major steps of the disambiguation method are; explained. Cross-validated evaluation results'. for German (88.6-94.4% correct for binary a.ttachment ambiguities, 83.3- 92.5% correct fo interpretation ambiguities) show that disambiguation methods combin- ing interpretation' rules and statistical methods might yield significantly better results than nonhybrid disambiguation methods.
