Interpreting Language in Context in CommandTalk

CommandTalk [6] is a spoken language interface to the ModSAF [1] battlefield simulator that allows simulation operators to generate and execute military exercise by creating forces and control measures, assigning missions to forces, and controlling the display. ModSAF is a stochastic distributed entity-based simulation, where one operator controls a collection of forces, while other operators may simultaneously control other allied and/or opposing forces. This paper will focus on how two representations of context are used in CommandTalk to correctly interpret the user's spoken utterances: situational context represents the current state of the simulation, and linguistic context represents the history of the user's linguistic acts.
