In this paper we describe DISCUSS, a dialogue move taxonomy layered over semantic representations. We designed this scheme to enable development of computational models of tutorial dialogues and to provide an intermediate representation suitable for question and tutorial act generation. As such, DISCUSS captures semantic and pragmatic elements across four dimensions: Dialogue Act, Rhetorical Form, Predicate Type, Semantic Roles. Together these dimensions provide a summary of an utterance's propositional content and how it may change the underlying information state of the conversation. This taxonomy builds on previous work in both general dialogue act taxonomies as well as work in tutorial act and tutorial question categorization. The types and values found within our taxonomy are based on preliminary observations and on-going annotation from our corpus of multimodal tutorial dialogues for elementary school science education.
