ANR-funded Nomage project aims at describing the aspectual properties of deverbal nouns taken from a corpus, in an empirical way. It is centered on the development of two resources: a semantically and syntactically annotated corpus of deverbal nouns based on the French Treebank, and an electronic lexicon, providing descriptions of morphological, syntactic and semantic properties of the deverbal nouns found in our corpus. Both resources are presented in this paper, with a focus on the comparison between corpus data and lexicon data.
