Understanding service attributes of robot hotels: A sentiment analysis of customer online reviews

Robots and artificial intelligence are essential to the future of the hospitality industry, and they are receiving increasing interest from hotel managers and researchers. However, the adoption of robotic services in hotel operations is a challenging task owing to the current level of technology and lack of understanding on the relationship between various aspects of robotic services and customer satisfaction. Moreover, no prior study has examined the service attributes of robots in hotels. To fill these gaps, this study analyzes customers' sentiments on major hotels employing robotic services expressed through online reviews. A list of robot quality and oper-ational area attributes is first constructed, through which underperforming robot service areas are identified. Sentiments on robotic services have a positive correlation with hotel service satisfaction, which plays an important role in determining the overall satisfaction of customers. The analysis and findings are valuable to researchers and managers for future research and adoption of robotic services in hotels.
