Interaction Style Recognition Based on Multi-Layer Multi-View Profile Representation

Interaction Style (IS) refers to patterns of interaction containing highly contextual and innate information. Awareness of our IS can help us discover interpersonal conflicts and guide us how to interact with others. Recently, automatic IS recognition is becoming increasingly important in the design of a dialogue system for harmonious interaction. With the goal to select appropriate responses, four IS types proposed by Berens are selected as the basis for our study. In this study, multiple views (multi-views) of the utterances during interaction, including emotions and dialogue topics, are recognized first. Inspired by the emotion profile theory, the IS profiles are then extracted using the multi-view features to better characterize the IS of the interactional utterances. Similar to the multilayer architectures in deep neural networks, a multi-layer multi-view IS profile representation method, structured layer by layer through embedding the multi-views, is proposed to better interpret intermediate representations in the feature space of the interactional utterances based on a probabilistic fusion model. The IS is finally recognized by using the Support Vector Machine (SVM) based on the obtained IS profiles. Experimental results demonstrate that the proposed method achieved an encouraging IS recognition accuracy and outperformed the previous method.
