Text Understanding systems often commit to a single best interpretation of a sen- tence before analyzing subsequent text. This interpretation is chosen by resolv- ing ambiguous alternatives to the one with the highest confidence, given the context available at the time of commitment. Sub- sequent text, however, may contain infor- mation that changes the confidence of al- ternatives. This may especially be the case with multiple redundant texts on the same topic. Ideally, systems would de- lay choosing among ambiguous alterna- tives until more text has been read. One solution is to maintain multiple can- didate interpretations of each sentence un- til the system acquires disambiguating ev- idence. Unfortunately, the number of al- ternatives explodes quickly. In this pa- per, we propose a pa...
