... a considerable engineer- ing effort, yet there is very limited avail- ability of off-the shelf tools for researchers whose interests are not in coreference, or for researchers who want to concentrate ... the use of coreference information in summa- rization or question answering techniques is not as widespread as it could be. We believe that the avail- ability of a modular toolkit for...

AET provides a formalism for describing how a formula consisting of lexical ... equivalences is a conjunction of atomic formulas rather than arbitrary formula. We demand that an RLDT be nonrecursive. In- formally RLDT nonrecursivness means that for any set o...
