MIMIC: An Adaptive Mixed Initiative Spoken Dialogue System for Information Queries
نویسنده
چکیده
This paper describes MIMIC, an adaptive mixed initiative spoken dialogue system that provides movie showtime information. MIMIC improves upon previous dialogue systems in two respects. First, it employs initiative-oriented strategy adaptation to automatically adapt response generation strategies based on the cumulative effect of information dynamically extracted from user utterances during the dialogue. Second, MIMIC's dialogue management architecture decouples its initiative module from the goal and response strategy selection processes, providing a general framework for developing spoken dialogue systems with different adaptation behavior.

Evaluating Automatic Dialogue Strategy Adaptation for a Spoken Dialogue System
In this paper, we describe an empirical evaluation of an adaptive mixed initiative spoken dialogue system. We conducted two sets of experiments to evaluate the mixed initiative and automatic adaptation aspects of the system, and analyzed the resulting dialogues along three dimensions: performance factors, discourse features, and initiative distribution. Our results show that 1) both the mixed i...
متن کاملIdentification of Speaker Actions in Mixed Initiative Dialogue
Today’s state-of-the-art spoken language dialogue systems (SLDSs) are mainly system-directed leaving very little initiative to the user. This paper discusses how to enable controlled steps in the direction of mixedinitiative SLDSs. The discussion is based on experience from the design, implementation and test of system-directed dialogue for a spoken language dialogue system and on first Wizard ...
متن کاملEvaluation of a Dialogue System Based on a Generic Model that Combines Robust Speech Understanding and Mixed-initiative Control
This paper presents a generic model to combine robust speech understanding and mixed-initiative dialogue control in spoken dialogue systems. It relies on the use of semantic frames to conceptually store user interactions, a frame-unification procedure to deal with partial information, and a stack structure to handle initiative control. This model has been successfully applied in a dialogue syst...
متن کاملMINOS-II: a prototype car navigation system with mixed initiative turn taking dialogue
Spoken dialogue systems are classified into three types from the viewpoint of turn taking. Dialogue can be led by the system (system initiative), the user (user initiative), and their mixture (mixed initiative). In this paper, EUROPA, a framework for developing spoken dialogue systems, is introduced. EUROPA is applied to prototyping a car navigation system called MINOS-II. MINOS-II deals with a...
متن کاملAn Efficient Language Understanding Approach for Mixed-Initiative Spoken Dialogue Systems
A practical spoken dialogue system in a mixed-initiative scheme must be able to handle a variety of concepts supplied by users. This is mostly responsible by a language understanding module, which converts an input word string to a semantic concept understood by the system. This article proposes a novel language understanding approach, which consists of two modules, a subframe extraction module...
