I1. is often assumed that when natural language processing meets the real world, the ideal of aiming for complete and correct interpretations has to be abandoned. However, our experience with TACITUS; especially in the MUC-3 eval- uation, has shown that. principled techniques fox' syntactic and pragmatic analysis can be bolstered with methods for achieving robust- ness. We describe three techniques for mak- ing syntactic analysis more robust--an agenda- based scheduling parser, a recovery technique for failed parses, and a new technique called ter- minal substring parsing. For pragmatics pro- cessing, we describe how the method of ab- ductive inference is inherently robust, in that an interpretation is always possible, so that in the absence of the required world knowledge, performance deg...
