A Personalized Tourist Trip Design Algorithm for Mobile Tourist Guides
نویسندگان
چکیده
Mobile Tourist Guides evolve towards automated personalised tour planning devices [4]. The contribution of this paper 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 [3], is used as a starting point for modelling the TTDP. The problem involves a set of possible locations having a score and the objective is to maximise the total score of the visited locations, while keeping the total time (or distance) below the available time budget. The score of a location represents the interest of a tourist in that location. Scores are calculated using the Vector Space Model [1], which is a well-known technique from the field of Information Retrieval. The TTDP is solved using a Guided Local Search meta-heuristic [5]. In order to compare the performance of this approach with an algorithm that appeared in the literature [2], both are applied to a real data set from the city of Ghent. A collection of tourist points of interest with descriptions was indexed and subsequently queried with popular interests, which resulted in a test set of TTDPs. The approach presented in this paper turns out to be faster and produces solutions of better quality. This paper is published in Applied Artificial Intelligence 22 (10): 964–985, 2008.

The use of mobile devices as electronic tourist guides represents a recent trend that brings the concept of ‘mobile tourism’ into the spotlight. While much of the underlying technology is already available, there are still open challenges with respect to design, usability, portability and implementation aspects. Most existing ‘mobile tourism’ solutions either represent of-the-shelf applications...
متن کاملContext-Aware Tourist Trip Recommendations
Mobile and web-based services solving common tourist trip design problems are available, but only few solutions consider context for the recommendation of point of interest (POI) sequences. In this paper, we present a novel approach to incorporating context into a tourist trip recommendation algorithm. In addition to traditional context factors in tourism, such as location, weather or opening h...
متن کاملe-Turist: Electronic Mobile Tourist Guide
In the e-Turist project we developed a mobile application that provide experience comparable to that offered by a professional tour guide, but tailored to each individual tourist. The tourist can enter his interests (entertainment, active tourism, gastronomy, cultural and natural heritage), the available time and any special requirements he/she may have. Based on these and other data such as op...
