  Artificial Intelligence (AI) has been improving the performance of systems
for a diverse set of tasks and introduced a more interactive generation of
personal agents. Despite the current trend of applying AI for a great amount of
areas, we have not seen the same quantity of work being developed for the
tourism sector. This paper reports on the main applications of AI systems
developed for tourism and the current state of the art for this sector. The
paper also provides an up-to-date survey of this field regarding several key
works and systems that are applied to tourism, like Personal Agents, for
providing a more interactive experience. We also carried out an in-depth
research on systems for predicting traffic human flow, more accurate
recommendation systems and even how geospatial is trying to display tourism
data in a more informative way and prevent problems before they arise.
