		<pub:abstract><![CDATA[We present an architectural support for building context-aware
applications. With the increasing acceptance of dynamic mobile and
ubiquitous computing environments, applications are no longer limited to
relying only on the information explicitly provided by users. Instead,
these environments invite a new kind of applications leveraging from
implicit information that can range from a simple time-of-a-day
information to information about user location to even an elaborate
description of user current activity. This implicit information is known as
the context, and although the context-aware computing paradigm has been
introduced over a decade ago, so far there exist only a limited number of
context-aware applications available to everyday users. We believe that
this is due to the tight coupling of contextual operations where each
application is required to sense, collect, interpret and apply all information
independently from others. To overcome this issue we propose a
decoupled approach, where the information sensing, aggregation, and
interpretation is provided by external services, and applications are
concerned with only applying the contextual information to their needs.
Moreover, we focus on the design and specification of a generic service
capable of both aggregating and interpreting context information as part
of the Me-Centric computing project, and demonstrate its capability in an
office-based scenario.]]></pub:abstract>
