This paper describes the Bridge system, a system designed to robustly map from natural language sentences to abstract knowledge representations. The system runs on PARC’s parser, generator, and ordered rewrite platform XLE. The Bridge system has been extended to include a type of light inference, based on an entailment and contradiction detection algorithm which also runs on XLE. The paper then describes a search and question answering application, Asker, which uses the Bridge system to create a semantic index of text passages and which allows a user to query the index in natural language.
