User Evaluation of a Multi-dimensional Statistical Dialogue System

This framework has been shown to substantially reduce data needs by leveraging domain-independent dimensions, such as social obligations or feedback, which (as we show) can be transferred between domains. In this paper, we conduct a user study and show that the performance of a multidimensional system, which can be adapted from a source domain, is equivalent to that of a one-dimensional baseline, which can only be trained from scratch. 1 Introduction Data-driven approaches to spoken dialogue systems (SDS) are limited by their reliance on substantial amounts of annotated data in the target domain. This can be addressed by considering transfer learning techniques, e.g.
