Recommending a Sequence of Points of Interest to a Group of Users in a Mobile Context

Recommender systems (RSs) recommend points of interest (POIs), such as restaurants, museums or monuments, to users. In practice, tourists often travel in groups and want to visit a sequence of POIs along an enjoyable route. Recommending such a sequence of items to a group complicates the problem of travel recommendations because the preferences of all group members have to be taken into account. In this work, we want to examine how a RS can solve the so-called Tourist Trip Design Problem (TTDP) for a group of users. We present the most important components of our work and the research questions we want to be answered. We summarize the results we achieved so far and outline future work.
