Abstract
Firstly, deep learning has been successful in many fields in recent years. As a core application in natural language processing, dialogue system has gradually developed from traditional machine learning to deep learning. Secondly, the development of dialogue systems is briefly summarized, and then the typical dialogue systems based on deep learning are introduced in detail. In addition, we also introduce two developer-oriented dialogue system development platforms, including PyOpenDial and DeepPavlov. Finally, we discuss the development prospects and challenges of the dialogue system, including robustness, personalized, and startup problem. We believe that this review can help researchers better understand the development status in this field.
