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. | Generating Sentences from Different Perspectives Lee Fedder The Computer Laboratory University of Cambridge Pembroke Street Cambridge CB2 3QG England. lf@ Keywords Generation Natural Language interfaces. Abstract 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. Introduction The following sentences would have a different semantics if parsed yet they seem to specify the same state of affairs at some level of representation. la. I can stay until 5. lb. I must leave by 5. For generation we ought to be able to produce either. McDonald comments on these sentences - What mutually known cognitive structure do we recognise from them that would show them to be two sides of the same coin McDonald 1988 This paper describes a language generation system which is designed as the output component of a database interface and is capable of producing similar synonymous sentences. The architecture relies on a two level semantic representation one describes data in the system s application database and plays the role of McDonald s mutually known cognitive structure the other describes the semantics of sentences of Natural Language and the primitives correspond to specific entries in the lexicon. Information to be communicated is initially expressed in the application level semantics and is be mapped to the language level semantics as part of the generation process. Alternatives similar to la and lb arise during this mapping and represent a complexity inherent in language which did not exist in the original data - they are a property of the description. Application level information is described by linking it with .
