The Generation of Referring Expressions: Past, Present and Future

Abstract:
The task of referring expression generation is concerned with determining what semantic content should be used in a reference to an intended referent so that the hearer will be able to identify that referent. The task has been a focus of interest within natural language generation at least since the early 1980s, in part because the problem appears relatively well-defined. Over the last 25 years, a range of algorithms and approaches have been proposed and explored; and yet, even a casual analysis of real human-authored texts suggests that we have a long way to go in terms of providing an explanation for the range of real linguistic behaviour that we find. In this talk, I'll review research in the area to date, try to characterise where we are now, and point to directions for future research in the area.
