Abstract:& Mobile tourist guides evolve towards automated personalized tour planning devices. The contribution of this article is to put forward a combined artificial intelligence and metaheuristic approach to solve tourist trip design problems (TTDP). The approach enables fast decision support for tourists on small footprint mobile devices. The orienteering problem, which originates in the operational research literature, is used as a starting point for modelling the TTDP. The problem involves a set of possible locati… Show more
“…However, the benefits of personalization have been shown in a number of other scenarios -e.g. tourist guides (Souffriau et al, 2008), office applications (Bergman et al, 2004), e-commerce (Georgiadis, 2005), and learning systems (Economides, 2009). Although personalization (in its broadest sense) undoubtedly provides benefits, the evidence is not wholly unequivocal.…”
This article describes an experimental study investigating the impact on user experience of two approaches of personalization of content provided on a mobile device, for spectators at large sports events. A lab-based experiment showed that a system-driven approach to personalization was generally preferable, but that there were advantages to retaining some user control over the process. Usability implications for a hybrid approach, and design implications are discussed, with general support for countermeasures designed to overcome recognised limitations of adaptive systems.

“…Finally, we consider the uncertain traveling time between POIs through the completion probability constraint, which is absent in OP. While most works on OP focus on heuristic approaches [23,24] to estimate the global optimum of OP, we present an optimal solution to trip recommendation through a prefix based depth-first search strategy with a focus on efficiency through incremental reconstruction and dominance based pruning of routes.…”

As location-based social network (LBSN) services become increasingly popular, trip recommendation that recommends a sequence of points of interest (POIs) to visit for a user emerges as one of many important applications of LBSNs. Personalized trip recommendation tailors to users' specific tastes by learning from past check-in behaviors of users and their peers. Finding the optimal trip that maximizes user's experiences for a given time budget constraint is an NP hard problem and previous solutions do not consider two practical and important constraints. One constraint is POI availability where a POI may be only available during a certain time window. Another constraint is uncertain traveling time where the traveling time between two POIs is uncertain. This work presents efficient solutions to personalized trip recommendation by incorporating these constraints to prune the search space. We evaluated the efficiency and effectiveness of our solutions on real life LBSN data sets.
“…The requirements of the problem a PET has to solve can be modeled as the Tourist Trip Design Problem (TTDP) [10,11]. The Orienteering Problem (OP) [12] is the most basic version of the TTDP.…”
Abstract.When tourists are at a destination, they typically search for information in the Local Tourist Organizations. There, the staff determines the profile of the tourists and their restrictions. Combining this information with their up-to-date knowledge about the local attractions and public transportation, they suggest a personalized route for the tourist agenda. Finally, they fine tune up this route to better fit tourists' needs. We present an intelligent routing system to fulfil the same task. We divide this process in three steps: recommendation, route generation and route customization. We focus on the last two steps and analyze them. We model the tourist planning problem, integrating public transportation, as the Time Dependent Team Orienteering Problem with Time Windows (TDTOPTW) and we present an heuristic able to solve it on real-time. Finally, we show the prototype which generates and customizes routes in real-time.
