Due to the inherent complexity of building highly-interactive and personalized web applications, the development of a web-based travel advisory system can be a costly and timeconsuming task. We see this as one of the major obstacles to a more widespread adoption of such systems in particular with respect to small and medium-sized companies and e-Tourism platforms. The goal of the ADVISOR SUITE project discussed in this paper is thus to provide an off-the-shelf framework and development environment that allows us to build intelligent and easy-to-maintain advisory applications in a cost-efficient way: The main pillars of the presented system are therefore an integrated graphical modelling-environment, the provision of different domain-independent recommendation algorithms, as well as model-based mechanisms to fully generate functional web applications based on declarative definitions in a central knowledge repository. The paper discusses the core concepts and main functionalities of the...
