In this paper, we present an inference mecha- nism called the integrated parsing engine which provides a uniform abductive inference mech-- anism for natu~al language understmlding. It can (1) make phmsibh, assmnptiox~s, (2) rea~. son with mlfltiple alternatives, (3) switch the search process to the maximally plausible alter.. , native, (4) detect contradiction attd tame COlt -~ clutions which depend on inconsistent a,'~sump- tions, and (5) update plausibility factor of each befief based on new obsexvations. We demon- strafe that a.natural language understanding system using the integrated parsing engine as a subsystem can pursue a guided search for most t)lausible interpretation by making use of syn- tax, semantics, and contextual information.
