Abstract : In this work, we explore a combination of users’ sequential patterns and textual and categorical information in order to provide a user with a personalised itinerary of spatio-temporal activities during a distributed event (e.g. a cruise or a festival). Firstly, we model users’ interest in activities by combining textual and categorical information. Secondly, we retrieve users' sequential patterns to model their typical transitions between activities and categories. Finally, we model the itinerary construction problem as an instance of Orienteering Problem with Time Windows (OPTW) using the obtained interest scores. We incorporate sequential patterns in the iterative algorithm to solve it. We evaluate our approach on a dataset built over a cruise program.
