Abstract: We provide a formal description of the fundamental nonmonotonic operation used for discourse modeling. Our algorithm—overlay—consists of a default unification algorithm together with an elaborate scoring functionality. In addition to motivation and highlighting examples from the running system, we give some future directions. [ABSTRACT FROM AUTHOR]
