The AI Doctor Is In: A Survey of Task-Oriented Dialogue Systems for Healthcare Applications

Anonymous

Abstract: Task-oriented dialogue systems in healthcare are increasingly common and have been characterized by diverse architectures and objectives. Although they have been surveyed in the medical community from a non-technical perspective, a systematic review from a rigorous computational perspective remains noticeably absent. This has resulted in limited knowledge of important implementation and replicability details, slowing the pace of innovation. To fill this gap, we investigated an initial pool of 4070 papers from well-known computer science, natural language processing, and artificial intelligence venues, identifying 70 papers discussing the system-level implementation of task-oriented dialogue systems for healthcare applications. We comprehensively reviewed these papers, and present our key findings including identified gaps and corresponding recommendations.
