Limits of Simple Dialogue Acts for Tactical Questioning Dialogues
Ron Artstein, Michael Rushforth, Sudeep Gandhe, David R. Traum, Aram Donigian · 2011
A set of dialogue acts, generated automatically by applying a dialogue act scheme to a domain representation designed for easy scenario authoring, covers approximately 72%–76 % of user utterances spoken in live interaction with a tactical ques-tioning simulation trainer. The domain is represented as facts of the form object, attribute, value and conversational ac-tions of the form character, action. User utterances from the corpus that fall outside the scope of the scheme include ques-tions about temporal relations, relations between facts and re-lations between objects, questions about reason and evidence, assertions by the user, conditional offers, attempts to set the topic of conversation, and compound utterances. These ut-terance types constitute the limits of the simple dialogue act scheme.
