Improving unsegmented dialogue turns annotation with n-gram transducers.
CD Martínez-Hinarejos, V Tamarit... - 2009 - eprints.pascal-network.org
Abstract The statistical models used for dialogue systems need annotated data (dialogues)
to infer their statistical parameters. Dialogues are usually annotated in terms of Dialogue
Acts (DA). The annotation problem can be attacked with statistical models, that avoid ...

Abstract. The annotation of dialogues with Dialogue Acts is important to develop dialogue
systems. One way to do this annotation is using a method called N-gram Transducer (NGT),
that has shown very good results in unsegmented turns compared with other models, but ...
