Abstract

This paper proposes a probabilistic approach to the resolution of referring expressions for task-oriented dialogue systems. The approach resolves descriptions, anaphora, and deixis in a unified manner. In this approach, the notion of reference domains serves an important role to handle context-dependent attributes of entities and references to sets. The evaluation with the REX-J corpus shows promising results.
