The PALIO Framework for Adaptive Information Services

This chapter describes the PALIO (Personalised Access to Local Information and services for tourists) service framework, focusing on its extensive support for service adaptation. The PALIO framework is currently used in the development of location-aware information systems for tourists, and is capable of delivering fully adaptive information to a wide range of devices, including mobile ones. Its open and expandable architecture can integrate a variety of pre-existing and forthcoming services, and retrieve information from a collection of different databases. The framework supports dynamic adaptation both in the content and the presentation of information, according to user- and interaction contextcharacteristics. This chapter discusses how the aforementioned adaptation capabilities can support the creation of Multiple User Interfaces (MUIs) on the Web.
