Abstract
[This is an excerpt.] Chatbots are software applications that use steps or scripts to automate natural communication with users [1, 2]. Chatbots were first trialed in 1964 with ELIZA created by Joseph Weizenbaum, designed to act as a Rogerian psychotherapist [2,3]. Chatbots have been used in virtually every industry to afford customers communication via messaging without speaking with a human associate [3]. There are over 5100 chatbot programs today, with over 100 used in healthcare applications [4]. In 2020, the chatbot market was valued at US$ 17.17 billion and is projected to reach $102.29 billion by 2026. Major stakeholders in the market include IBM, Google, Amazon, Creative Virtual Ltd, LiveChat, and Facebook [5]. [To read more, click View Resource.]
