Talking with Machines: A Comprehensive Survey of Emergent Dialogue Systems (2305.16324v1)

Abstract: From the earliest experiments in the 20th century to the utilization of LLMs and transformers, dialogue systems research has continued to evolve, playing crucial roles in numerous fields. This paper offers a comprehensive review of these systems, tracing their historical development and examining their fundamental operations. We analyze popular and emerging datasets for training and survey key contributions in dialogue systems research, including traditional systems and advanced machine learning methods. Finally, we consider conventional and transformer-based evaluation metrics, followed by a short discussion of prevailing challenges and future prospects in the field.
