%0 Journal Article %T Computing Presuppositions by Contextual Reasoning %A Christof Monz %J Computer Science %D 2000 %I arXiv %X This paper describes how automated deduction methods for natural language processing can be applied more efficiently by encoding context in a more elaborate way. Our work is based on formal approaches to context, and we provide a tableau calculus for contextual reasoning. This is explained by considering an example from the problem area of presupposition projection. %U http://arxiv.org/abs/cs/0009019v1
