... structures in dependency pars- ing are dependency graphs. Therefore, as items for constituency parsers are defined as sets of par- tial constituency trees, it is tempting to define items for dependency ... i.e., the set of forests containing a single dependency tree of the form w i (w i ). This same set of hypotheses can be used for all the parsers, so we will not make it ex- plic...
