Automatic SemanticRole Annotation for Portuguese
Resumo
This paper describes an automatic annotation system for semantic roles, implemented as an independent addon module for syntactically parsed text. The formalism uses handwritten Constraint Grammar (CG) rules to map and disambiguate 40 different semantic roles. As a proofofconcept, an evaluation on treebank data was performed, where the system achieved an average Fscore of 88.6.Referências
