The design and implementation of a paraphrase component for a natural language questlon-answer system (CO-OP) is presented. A major point made is the role of given and new information in formulating a paraphrase that differs in a meaningful way from the user's question. A description is also given of the transformational grammar used by the paraphraser to generate questions. I • INTRO~ION In a natural language interface to a database query system, a paraphraser can be used to ensure that the system has correctly understood the user.
