Query: Real-world Conversational AI for Hotel Bookings   In this paper, we present a real-world conversational AI system to search for
and book hotels through text messaging. Our architecture consists of a
frame-based dialogue management system, which calls machine learning models for
intent classification, named entity recognition, and information retrieval
subtasks. Our chatbot has been deployed on a commercial scale, handling tens of
thousands of hotel searches every day. We describe the various opportunities
and challenges of developing a chatbot in the travel industry.
