Abstract

This paper presents a syntactic lexicon of Brazilian Portuguese predicative adjectives that are not regularly derived from verbs. From the 7,000 most frequent adjectives in a large web corpus, 3,161 lexical items were selected and annotated with 36 syntactic properties. These properties were established through introspection and corpus evidence, covering argument structure, copular verbs, prepositions, transformations (e.g., raising, nominalization), semantic roles, and others. The resulting resource constitutes a machine-readable lexicon of predicative adjectives for Brazilian Portuguese.
