ARRAU

Anaphora resolution and underspecification

About

The project

ARRAU was a project on anaphora interpretation funded by the EPSRC, grant number GR/S76434/01, that ran from 2004 to 2007.

Objectives

The objective of the ARRAU project was to study the cases of anaphoric reference most problematic for current anaphora resolution systems, in particular:

  • Reference to plurals
  • Reference to abstract objects such as events and plans
  • Ambiguous anaphoric expressions

Theoretical goals

  • Revise current models of the interpretation of plurals and events
  • Develop a model of reference to plans
  • Evaluate hypotheses about underspecification in reference to structured objects
  • Yield a better understanding of the phenomenon of (semantic) underspecification

Methods

  • Corpus analysis and annotation (University of Essex)
    • Identify questions to be studied through psychological studies
    • Produce an annotated corpus
  • Psychological experiments (University of Glasgow)
    • Provide empirical evidence to be used to modify our existing anaphora resolution system, which will be evaluated using the annotated corpus
