This paper shows an extended Discourse Representation Theory (DRT) model which represents clarification dialogue and clarification dialogue acts and relates them to agents’ intentions. Agents’ intentions are linked to the dialogue acts associated with their utterances. The effect dialogue acts have on the speaker and the hearer is translated into an extended computational DRT model and linked to agents’ beliefs. These extensions to DRT allow the demonstration of problematic dialogues that require clarification, a topic neglected in DRT.
