In this paper we present a brief look at some of the knowledge-based processes used in gener- atii~g referring expressions in the natural language advisory system WlSBER. Although WISBER is fully capable of exploiting syntactic information to generate contextually appropriate references, the work described here concen- trates on the use of conceptual and contingent knowledge about objects in the domain of discourse to generate natural-sounding refer- ences. A short description of the knowledge sources available is followed by examples of the processes that transform "deep structures" encodimg system intentions into verbalizable form. Finally, we discuss a number of pro- blems of specifier selection and their solution within a knowledge-based framework.
