Distinguishable entities
Monique Rolbert, Pascal Préa · 2009
Many studies in natural language processing are concerned with how to generate definite descriptions that evoke a discourse entity already introduced in the context.A solution to this problem has been initially proposed by Dale (1989) in terms of distinguishing descriptions and distinguishable entities.In this paper, we give a formal definition of the terms "distinguishable entity" in non trivial cases and we show that its properties lead us to the definition of a distance between entities.Then, we give a polynomial algorithm to compute distinguishing descriptions.
