Preliminary Results on Dialogue Act Classificationin Chat-based Online Tutorial Dialogues

2016; EDM; Vasile, R.; Banjade, R.; Maharjan, N.; Morrison, D.; Ritter, S.; Yudelson, M.

We present in this paper preliminary results with dialogue act classification in human-to-human tutorial dialogues. Dialogue acts are ways to characterize the intentions and actions of the speakers in dialogues based on the language-as-action theory. This work serves our larger goal of identifying patterns of tutors’ actions, in the form of dialogue act and subact sequences, that relate to various aspects of learning. The preliminary results we obtained for dialogue act classification using a supervised machine learning approach are promising.
