This document summarizes a research paper on chatbot recommender systems in tourism. The paper conducted a systematic literature review and benefit-cost analysis. It found that chatbots provide benefits like convenient responses to customers and cost savings for businesses. However, chatbots also have costs like some customers being uncomfortable interacting with machines and chatbots' limited ability to engage in open-ended conversations. The researchers concluded that while chatbots can improve customer service, businesses still need employees to handle complex issues and technophobic customers. Future work is needed to understand why some users are reluctant to use chatbots.
