2003 Proceedings of the second international workshop on Paraphrasing -  
We investigate lexical paraphrasing in the context of two distinct applications: document retrieval and node identification. Document retrieval -the first step in question answering -retrieves documents that contain answers to user queries. Node identification -performed in the context of a Bayesian argumentation system -matches users' Natural Language sentences to nodes in a Bayesian network. Lexical paraphrases are generated using syntactic, semantic and corpus-based information. Our
more » ... n shows that lexical paraphrasing improves retrieval performance for both applications.
