We demonstrate three classes of off-topic responses which allow a virtual question-answering character to handle cases where it does not understand the users input ask for clarification, indicate misunderstanding, and move on with the conversation. While falling short of full dialogue management, a combination of such responses together with prompts to change the topic can improve overall dialogue coherence.
