Culture and Emotion in Dialogue Management

The goal of my research is to integrate culture and emotion in dialogue management. I approach this subject from two angles: the training of a dialogue strategy and the creation of available system actions.


The first aspect is concerned with the challenges of adapting the dialogue strategy to culture, user emotion and system emotion simultaneously. The high amount of parameters that the dialogue strategy is adapted to results in new challenges for the training of the dialogue strategy. I investigate the performance of various machine learning approaches for adaptation to several parameters. Additionally, as the different input parameters might result in different preferences regarding the selected dialogue strategy, special consideration is given to relative importance of each input parameter. To further enhance the dialogue management, the influence the selected system action will have on the system emotion is taken into account by the dialogue strategy.
The second aspect covers the creation of dialogue contributions that are suitable choices for specific cultures or emotions. By providing a variety of system actions to choose from, the possibilities for behaviour of the dialogue manager can be expanded and it is more likely to find an adequate dialogue contribution. I investigate domain-independent variations of system actions, such as the level of verbosity or directness, and how they can be generated automatically.
