Usually descriptions of touristic products comprise information about accommodation, tourist attractions, or leisure activities. Tourist decisions for a product are based on personal characteristics, planned vacation activities, and specificities of potential touristic products. The decision should guarantee a high level of emotional and physical well-being, considering also some hard constraints like temporal and monetary resources, or travel distance. The starting point for the design of the described recommender system is a unified description of the preferences of the tourist and the opportunities offered by touristic products using the so-called Seven-Factor Model. For the assignment of the values in the Seven-Factor Model a predefined set of pictures is the pivotal instrument. These pictures represent various aspects of the personality and preferences of the tourist as well as general categories for the description of destinations, i. e., certain tourist attractions like landscape, cultural facilities, different leisure activities, or emotional aspects associated with tourism. Based on the picture selection of a customer a so-called Factor Algorithm calculates values for each factor of the Seven-Factor Model. This is a rather fast and intuitive method for acquisition of information about personality and preferences. The evaluation of the factors of the products is obtained by mapping descriptive attributes of touristic products onto the predefined pictures and afterwards applying the Factor Algorithm to the pictures characterizing the product. Based on this unified description of tourists and touristic products a recommendation can be defined by measuring the similarity between the user attributes and the product attributes. The approach is evaluated using data from a travel agency. Furthermore other possible applications are discussed.
