This document reviews 13 papers related to using data analytics and machine learning techniques to analyze tourist behavior from large datasets. The papers explore using geotagged photos, reviews, and location data to cluster and classify tourist activities and interests, identify representative landmarks and destinations, predict future locations, and uncover patterns in tourist flows and behaviors. Machine learning methods discussed include density-based clustering, convolutional neural networks, random forest classification, and deep learning models. The goal of this research is to better understand tourist preferences and decision-making to help tourism organizations improve destination management and personalize services.
