While it is known that traditional recommendation algorithms’ performance depends on data characteristics like sparsity, popularity bias, and preference distributions, the impact of these data characteristics has not been systematically studied in the POI recommendation domain. To fill this gap, we extend a pr...

Data-driven Destination Recommender Systems

Finally, we propose a city recommender system that supports users making the trade-offs involved in their travel choices.
