Abstract: | More and more Web users ask for contents and services highly tailored to their particular contexts of use. Especially due
to the increasing affordability of new and powerful mobile communication devices, they also appreciate the availability of
ubiquitous access, independent from the device actually in use. Due to such premises, traditional software design methods
need to be extended, and new issues and requirements need to be addressed for supporting context-aware access to services
and applications. In this paper we propose a model-driven approach towards adaptive, context-aware Web applications, accompanied
by a general-purpose execution framework enabling active context-awareness. Whereas conventional adaptive hypermedia systems address the problem of adapting HTML pages in response to user-generated
requests, in this work we especially stress the importance of user-independent, context-triggered adaptivity actions. This
finally leads us to interpret the context as an active actor, operating independently from users during their navigations. |
