dependency tree structure

IT-VaLex is a collection of verbal lexical entries enhanced with valency and subcategorization frames at syntactic level. IT-VaLex is closely related to the Index Thomisticus Treebank project, since it is a corpus-driven valency lexicon automatically induced from the syntactic layer of annotation of the Index Thomisticus Treebank. In the Index Thomisticus Treebank annotation style, verbal arguments are those assigned the following tags: Sb (Subject), Obj (Object), OComp (Object Complement) and Pnom (Predicate Nominal).

The difference between IT-VaLex and VALLEX is that the former derives from the syntactically annotated data of the Index Thomisticus Treebank, the latter is connected with the semantic/pragmatic annotation of both the Latin treebanks (plus a number of hard-coded entries).
