Extracting and Modelling Preferences from Dialogue

Abstract. Dialogue moves influence and are influenced by the agents’ preferences. We propose a method for modelling this interaction. We motivate and describe a recursive method for calculating the preferences that are expressed, sometimes indirectly, through the speech acts performed. These yield partial CP-nets, which provide a compact and efficient method for computing how preferences influence each other. Our study of 100 dialogues in the Verbmobil corpus can be seen as a partial vindication of using CP-nets to represent preferences.
