This paper presents a computational model of how conversational participants collaborate in making referring expressions. The model is based on the planning paradigm. It employs plans for constructing and recognizing referring expressions and meta-plans for constructing and recognizing clarifications. This allows the model to account for the generation and understanding both of referring expressions and of their clarifications in a uniform framework using a single knowledge base. | Collaborating on Referring Expressions Peter A.

Person A does this by uttering a referring expression however A s expression fails to allow B to uniquely identify the object. Person B then tries to clarify A s referring expression by expanding it. A rejects B s clarification and replaces it which allows B to identify the referent of the refashioned referring expression. A 1 See the weird creature B 2 In the corner A 3 No on the television B 4 Okay. This paper presents a computation model of Clark and Wilkes-Gibbs s work on how conversational participants collaborate in forming referring expressions 2 . Our model takes the role of one of the participants either the participant who initiates the referring expression the initiator or the one who is trying to identify the referent the responder. It accounts for how the initiator constructs the initial referring expressions and how she and the responder then collaborate in clarifying the referring expression until it is acceptable. Each step of the collaboration consists of a clarification of the referring expression and a subsequent understanding of the clarification. This work is based on the planning paradigm. The knowledge that is needed to choose the content of a referring expression is encoded in plans. This allows an
