Certain pairs or groups of sentences appear to be semantically distinct, yet specify the same underlying state of affairs, from different perspectives. This leads to questions about what that underlying state of affairs might be, and, for generation, how and why the alternative expressions might be produced. This paper looks at how such sentences may be generated in a Natural Language interface to a database system.
