Error Return Plots

Error-return plots show the rate of error(misunderstanding) against the rate of non-return(non-understanding) for Natural Language Processing systems. They are a useful visual tool for judging system performance when other measures such as recall/precision and detection-error tradeoff are less informative, specifically when a system is judged on the correctness of its responses, but may elect to not return a response.
