Toward Designing a Realistic Conversational System: A Survey
Awrad Mohammed Ali, Avelino J. González · Journal of International Crisis and Risk Communication Research · 2016
Over the past few years, the importance of having realistic conversational systems that satisfy the user needs have encouraged researchers to investigate new approaches for intelligent systems that are able to handle the required dialogues. However, designing a realistic conversational system that is able to understand the nuances of human conversation is not an easy task; thus, researchers face several challenges. To address these challenges and to help guide future research, we provide in this paper an overview of the most recent works in conversational systems. We classify the current models based on their functional similarities to address common features among the described systems. We also summarize the methods and approaches used by each system, state the systems limitations, and highlight their strengths.
