The document discusses personalization and context-aware services. It describes how personalization involves linking user preferences, devices, services and context to provide a customized experience. Personalization requires an expandable user profile that captures preferences and restrictions for different applications and services. The use of semantics and ontologies is proposed to conceptualize profiles and contexts in order to better integrate and adapt services to user needs. The challenges of usability, infrastructure variability and technology complexity are also addressed to ensure personalization enhances rather than hampers the user experience.
