Recommender Systems in Tourism: A Case for Interactive Approaches

by Dietmar Jannach, Alpen-Adria-Universität Klagenfurt, Austria


There are various ways in which recommender systems can support their users in touristic contexts, from the selection of a destination, over pre-trip itinerary planning, to point-of-interest recommendation during the trip. In many of these application scenarios, building a recommender system solely on long-term interest profiles is not possible. Instead, interactive approaches are required in which users have the opportunity to interactively state and eventually revise their needs and preferences, and where the system is also able to explain its suggestions.

In this talk, we first review several application scenarios for recommender systems in tourism and summarize their specific requirements. We then focus on interactive recommendation approaches and specifically address the topics of explanations for recommender systems and mechanisms for user control.
