The talk will be organized into three sections:
a) the long-time connection between Latin and computational linguistics. Some documents coming from the 'Busa Archive' will be presented concerning (1) the genesis of the Index Thomisticus in the 40s and (2) the relations between father Roberto Busa SJ and Prague in the 60s;
b) issues in tectogrammatical annotation of Latin. The treatment of some Latin-specific constructions will be shown;
c) a comparison between the tectogrammatical-based valency lexicon Latin-Vallex and Latin WordNet. The degree of overlapping between some subsets taken from the two lexical resources will be presented.
