Pix2Trips – a system supporting small groups of urban tourists

Group recommendation systems are the subject of many publications, but still is a gap between research results and group decision support systems' needs. Tourists often do not know which attractions they would like to visit. The Pix2Trips system asks the group's members to indicate images that they would like. On this basis, Pix2Trips models the group's preferences and adjusts them to the proposed places' models. Some tourist places in Wroclaw city, Poland, were used in experiments. The paper presents the system's components and discusses the results of the experiments. Conclusions indicate the good overall evaluation of the Pix2Trips system and further research.
