What Decisions Have You Made?: Automatic Decision Detection in Meeting Conversations

چکیده
This study addresses the problem of automatically detecting decisions in conversational speech. We formulate the problem as classifying decision-making units at two levels of granularity: dialogue acts and topic segments. We conduct an empirical analysis to determine the characteristic features of decision-making dialogue acts, and train MaxEnt models using these features for the classification tasks. We find that models that combine lexical, prosodic, contextual and topical features yield the best results on both tasks, achieving 72% and 86% precision, respectively. The study also provides a quantitative analysis of the relative importance of the feature types.

متن کاملCollaborative Decisionmaking and Personal Knowledge Management with R-Objects PepperTM
How do you make decisions? By thinking about the problem for a little while and then deciding in favor of "what feels right?" Does the way you make a decision depend on how important the decision is? Have you ever overlooked critical information at the time when you originally made the decision and why did you? Do you ever have to go back, re-think, and then decide differently, and if so, how d...
