LexInfo is a companion ontology to OntoLex-Lemon that provides a controlled vocabulary for linguistic metadata: part of speech (noun, verb, adjective), morphological features (tense, mood, number, gender, case), and syntactic frames. Adding LexInfo annotations to exported lexical data would allow consumers to understand the grammatical role of OFType names and verbalization components — for example, whether a role name is a noun or verb, or what inflected forms are expected.
