In this paper, we present and evaluate models of referring expression generation that mimic this human non-determinacy and show that this enables us to generate varied references in texts, which, in terms of coherence and comprehensibility, did not yield significant differences from human-produced references according to human judges.
in this study we focus on the choice of referential form, which is the first decision to be made by referring expression generation models (Reiter and Dale, 2000) and which determines whether a reference takes the form of a proper name, a pronoun, a definite description, etc.
