Tagging Semantic Types for Verb Argument Positions

Verb argument positions can be described by the semantic types that characterise the words filling that position. We investigate a number of linguistic issues underlying the tagging of an Italian corpus with the semantic types provided by the T-PAS (Typed Predicate-Argument Struc- ture) resource. We report both quantitative data about the tagging and a qualitative analysis of cases of disagreement between two annotators.
