The impact of service robots on customer satisfaction online ratings: The moderating effects of rapport and contextual review factors
研究了酒店服务机器人使用与顾客在线满意度评分的关系，发现顾客与机器人的融洽关系能增强满意度，而顾客在评论中提及机器人的努力程度会削弱该关系，移动设备发评的满意度更高。
Abstract Recent research has established a positive relationship between the use of service robots powered by artificial intelligence in hospitality firms and customer satisfaction online ratings, a particularly important form of electronic word of mouth. However, it is not clear if and how this relationship is augmented or diminished by moderating factors. In this study, we examined four potential moderators by using machine learning and natural language processing techniques to analyze 20,166 online reviews of hotels that had implemented service robots. We had four key findings. First, a positive service robot‐satisfaction rating relationship was further enhanced by improved customer‐service robot rapport during the service encounter. Second, higher customer effort focused on service robots in a review reduced the service robot‐satisfaction rating relationship. Third, posting reviews using a mobile device (vs. other devices) showed higher satisfaction ratings. Finally, customers' prior experience in writing online reviews was unrelated to the service robot‐satisfaction rating relationship. Taken together, these results suggest that service robots should be designed to be interactive and encourage customers to build rapport, for example, by service robots engaging in conversational flows. Moreover, customers should be nudged to use their mobile devices to post timely reviews on their positive human–robot interactions.
