The core of the problem is finding a way of describing the intended referent that distinguishes it from other potential referents with which it might be confused. We refer to this problem as the c o n t e n t d e t e r m i n a t i o n task. In this paper, we point out some limitations in an earlier solution proposed in Dale [1988, 1989], and discuss the possibilites of extending this solution by incorporating a use of constraints motivated by the work of Haddock [1987, 1988].
