A Survey on Dialogue Systems: Recent Advances and New Frontiers
This is a survey paper that synthesizes existing knowledge for researchers in dialogue systems, offering no new experimental results or incremental contributions.
The paper provides an overview of recent advances in dialogue systems, highlighting the role of deep learning in improving feature representations and response generation, and discusses potential research directions for future development.
Dialogue systems have attracted more and more attention. Recent advances on dialogue systems are overwhelmingly contributed by deep learning techniques, which have been employed to enhance a wide range of big data applications such as computer vision, natural language processing, and recommender systems. For dialogue systems, deep learning can leverage a massive amount of data to learn meaningful feature representations and response generation strategies, while requiring a minimum amount of hand-crafting. In this article, we give an overview to these recent advances on dialogue systems from various perspectives and discuss some possible research directions. In particular, we generally divide existing dialogue systems into task-oriented and non-task-oriented models, then detail how deep learning techniques help them with representative algorithms and finally discuss some appealing research directions that can bring the dialogue system research into a new frontier.
