A domain model centered approach to spoken language dialog systems
نویسنده
چکیده
This paper presents a view of Spoken Language Dialog Systems in which a Domain Model is the unifying feature, providing a common representation of knowledge about the domain of application that is shared by many components of the system. The information in the Domain Model is used in different ways by the grammar and parser, the speech recognizer, the dialog manager, and the back end interface. Sharing a common knowledge base allows these components to operate together seamlessly, while maintaining modularity.

Domain adaptation augmented by state-dependence in spoken dialog systems
In the development of spoken dialog systems, domain adaptation and dialog state-dependent language model are usually researched separately. This paper proposes a new approach for domain adaptation augmented by the dialog state-dependence, which means a dialog turn based cache model decaying synchronously with the dialog state change. Through this approach it’s more simple and rapid to adapt a C...

متن کاملWhat's in an ontology for spoken language understanding
Current Spoken Language Understanding systems rely either on hand-written semantic grammars or on flat attribute-value sequence labeling. In both approaches, concepts and their relations (when modeled at all) are domain-specific, thus making it difficult to expand, port or share the domain model. To address this issue, we introduce: 1) a domain model based on an ontology where concepts are clas...
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...
