We develop the default logic for pragmatic analysis of natural language queries. Ambiguous sentences are considered so that each set of meanings is assigned an extension of default system. The approach is applied to natural language question answering, where even a correct semantic representation needs to be modified in accordance to the set of default rules to better match a knowledge domain.
