Formal Constraints on Dependency Syntax

ArXi:2604.04542v1 Announce Type: new Dependency syntax represents the structure of a sentence as a tree composed of dependencies, i.e., directed relations between lexical units. While in its general form any such tree is allowed, in practice many are not plausible or are very infrequent in attested language. This has motivated a search for constraints characterizing subsets of trees that better fit real linguistic phenomena, providing a accurate linguistic description, faster parsing or insights on language evolution and human processing.
