Abstract
Due to an increasing number of online reviews in social media sites it has become vital for destinations, and businesses alike, to capture and regularly analyze these reviews to gain valuable new knowledge as input to managerial decision support. However, in practice, the possibility to manually extract and analyze the vast amount of available online reviews is fairly limited. Thus, the focus of this chapter is to highlight how knowledge from social media is utilized in the prototypically implemented destination management information system, DMIS-Åre. In order to extract and analyze user generated content from the social media platforms TripAdvisor.com and Booking.com a recently validated framework applying machine-learning methods and a dictionary-based approach is presented. © 2018 selection and editorial matter, Marianna Sigala and Ulrike Gretzel; individual chapters, the contributors.
