Abstract

This paper analyzes the semantic parsing of relative clauses in Portuguese in two meaning representation frameworks: Abstract Meaning Representation (AMR) and Lexicalized Meaning Representation (LMR). While both treat relatives as noun modifiers, AMR fails to distinguish restrictive from appositive clauses–an important traditional grammatical distinction. We argue for explicitly encoding this difference. The study draws on annotated translations of *The Little Prince* (Saint-Exupéry, 1943) in Brazilian and European Portuguese, highlighting issues in the Brazilian AMR annotations.
