Summary:

Recommender systems are widely used tools in a large number of online applications due to their ability to learn the tastes and needs of the users. Venue recommendation approaches have recently become
particularly useful, and even though these techniques have certain characteristics that differ from traditional recommendation, they deserve special attention from the research community due to the increase on the number of applications using tourism information to perform venue suggestions. In particular, how to properly evaluate (in an offline setting) this type of recommenders needs to be better analyzed, as they are normally evaluated using standard evaluation methodologies, neglecting their unique features. In this paper, we discuss and propose some solutions to two specific aspects around this problem: how to deal with already interacted venues in the test set and how to incorporate the sequence of visited venues by the user when measuring the performance of an algorithm (i.e., in an evaluation metric).
