After Dialog Went Pervasive: Separating Dialog Behavior Modeling and Task Modeling.

摘要
Dialog Goes Pervasive Until recently, many dialog systems were information retrieval systems. For example, using a telephone-based interactive response system a US-based user can find flights from United (1-800-UNITED-1), get movie schedules (1-800-777-FILM), or get bus information (Black et al., 2011). These systems save companies money and help users access information 24/7. However, the interaction between user and system is tightly constrained. For the most part, each system only deals with one domain, so the task models are typically flat slot-filling models (Allen et al., 2001b). Also, the dialogs are very structured, with system initiative and short user responses, giving limited scope to study important phenomena such as coreference.
