چکیده
This paper presents a new approach for dynamically increasing the coverage of a Statistical Dialog Manager. A Stochastic Finite-State Transducer for dialog management is estimated using a dialog simulator. This corpusbased model can cover most typical user behavior; however, sometimes unexpected situations may arise. Whenever these situations occur, the Dialog Manager model has no information to determine the next action. To deal with this problem, an Online Dialog Simulator is used in order to obtain synthetic dialogs for re-estimating the model and allowing the Dialog Manager to continue the dialog. This approach has been evaluated with real users in a sport facilities booking task.

Portability of Semantic Annotations for Fast Development of Dialogue Corpora
Generalization of spoken dialogue systems increases the need for fast development of spoken language understanding modules for semantic tagging of speaker’s turns. Statistical methods are performing well for this task but require large corpora to be trained. Collecting such corpora is expensive in time and human expertise. In this paper we propose a semi-automatic annotation process for fast pr...
متن کاملLeveraging study of robustness and portability of spoken language understanding systems across languages and domains: the PORTMEDIA corpora
The PORTMEDIA project is intended to develop new corpora for the evaluation of spoken language understanding systems. The newly collected data are in the field of human-machine dialogue systems for tourist information in French in line with the MEDIA corpus. Transcriptions and semantic annotations, obtained by low-cost procedures, are provided to allow a thorough evaluation of the systems’ capa...
متن کاملSpoken language understanding using layered n-gram modeling
This paper presents an approach which integrates layer concept information into the trigram language model in order to improve the understanding accuracy for spoken dialogue systems and to improve the portability of the language modeling materials among different narrow-domain applications. With this approach, both the recognition accuracy and out-of-grammar problem can be largely improved, and...

متن کاملAutomatic annotation of context and speech acts for dialogue corpora
Richly annotated dialogue corpora are essential for new research directions in statistical learning approaches to dialogue management, context-sensitive interpretation, and contextsensitive speech recognition. In particular, large dialogue corpora annotated with contextual information and speech acts are urgently required. We explore how existing dialogue corpora (usually consisting of utteranc...
