Abstract

Modeling user preferences is crucial in many real-life problems, ranging from individual and collective decision-making to strategic interactions between agents and game theory. Since agents do not come with their preferences transparently given in advance, we have only two means to determine what they are if we wish to exploit them in reasoning: we can infer them from what an agent says or from his nonlinguistic actions. In this paper, we analyze how to infer preferences from dialogue moves in actual conversations that involve bargaining or negotiation. To this end, we propose a new annotation scheme to study how preferences are linguistically expressed in two different corpus genres. This paper describes the annotation methodology and details the inter-annotator agreement study on each corpus genre. Our results show that preferences can be easily annotated by humans.
