This paper describes the results of corpus and experimental investigation into the factors that affect the way clarification questions in dialogue are interpreted, and the way they are responded to. We present some results from an investigation using the BNC which show some general correlations between clarification request type, likelihood of answering, answer type and distance between question and answer. We then describe a new experimental technique for integrating manipulations into text-based synchronous dialogue, and give more specific results concerning the effect of word category and level of grounding on interpretation and response type.
