摘要：This article presents PFN-PT, a robust system for the automatic semantic annotation of Portuguese, consisting of a new, parsing-oriented framenet and a rule-based frame- and role-tagger. The framenet provides almost 13,000 valency frames covering 7,300 verb lemmas with 10,700 senses. Frame and role tagging is achieved by iterated matching of syntactic structures and semantic noun types with slot-filler conditions in the framenet. We discuss design principles and present frame and role statistics. In an evaluation run on news data, the system achieved an overall F-score of 92.2% for frame senses.
