Language is central to how people reason about and understand their world. As computers increasingly pervade human lives and decision-making processes, they must learn to understand and mediate human-to-human interaction. People use their intuitive knowledge of the world and the experiences they've had in the past to react intelligently to the world around them. If we were to give machines these capabilities, they could help us make better-informed decisions, conquer mountains of data, and expand the reach of our creativity and intelligence.
