Traditional computational approaches to re- ferring expression generation operate in a de- liberate manner, choosing the attributes to be included on the basis of their ability to dis- tinguish the intended referent from its dis- tractors. However, work in psycholinguis- tics suggests that speakers align their refer- ring expressions with those used previously in the discourse, implying less deliberate choice and more subconscious reuse. This raises the question as to which is a more accurate char- acterisation of what people do. Using a cor- pus of dialogues containing 16,358 referring expressions, we explore this question via the generation of subsequent references in shared visual scenes. We use a machine learning ap- proach to referring expression generation and demonstrate that incorp...
