CHAT-Bot: A cultural heritage aware teller-bot for supporting touristic experiences

•Develop a methodology in the field of tourism able to define the context based on the analysis of the text.•Satisfying the needs of the tourist, based on personal preferences and the current context.•Develop a chatbot model that uses contextual information to maintain a fluid and natural dialog with users. Cultural heritage is an important resource that allows us to know and promote a territory. In this respect, it is important to experiment with the enhancement of cultural heritage by adopting approaches that meet the dynamic needs of various types of users. The aim of this paper is to introduce a recommender system capable of developing adaptive tourist routes. In fact, the proposed system suggests points of interest and related services according to both the profile of the tourist and contextual aspects. In particular, the interaction of the user with the system occurs through a chatbot that allows to build a real dialog. In order to show the potential of the proposed approach, a prototype was developed to support the user in building a customized tourist route related to some of the most important cultural sites in Campania (a region in Southern Italy): Herculaneum, Paestum and Pompeii.
