A simple formalism is proposed to repre- sent the contexts in which pronouns, def- inite/indefinite descriptions, and ordinal descriptions (e.g. 'the second book') can be used, and the way in which these ex- pressions change the context. It is shown that referring expressions can be gener- ated by a unification grammar provided that some phrase-structure rules are spe- cially tailored to express entities in the current knowledge base.
