Language is sensitive to both semantic and pragmatic effects. To capture both effects, we model language use as a cooperative game between two players: a speaker, who gener- ates an utterance, and a listener, who responds with an action. Specifically, we consider the task of generating spatial references to ob- jects, wherein the listener must accurately identify an object described by the speaker. We show that a speaker model that acts op- timally with respect to an explicit, embedded listener model substantially outperforms one that is trained to directly generate spatial de- scriptions.
