Data generation approaches for topic classification in multilingual spoken dialog systems
MetadataShow full item record
The conception of spoken-dialog systems (SDS) usually faces the problem of extending or adapting the system to multiple languages. This implies the creation of modules specically for the new languages, which is a time consuming process. In this paper, we propose two methods to reduce the time needed to extend the SDS to other languages. Our methods are particularly oriented to the topic classication and semantic tagging tasks and we evaluate their eectiveness on topic classication for three languages: English, Spanish, French.
