Towards A Wide-Coverage Grammar: Graphical Abstract Categorial Grammars

We present work whose ultimate goal is the creation of a wide-coverage abstractcategorial grammar (ACG) that could be used to automatically build discourse-levelrepresentations. In our work, we advance towards that goal by laying down the foun-dations necessary for building wide-coverage ACGs.Wefirstexamineexistinglanguageresources,inparticulartheFrigraminteractiongrammar and its lexicon Frilex, and assess their utility to building a wide-coverageACG. We then present our implementation of the ACG machinery which allows us toexperiment with grammars lexicalized by Frilex. Finally, we consider the challenge ofintegratingthetreatmentofdisparatelinguisticconstraintsinasingleACGandproposea generalization of the formalism: graphical abstract categorial grammars. The reportconcludes with an exploration of some of the formal properties of graphical ACGs.
