Workshop Scope
-----------------------------------------------------------------
Many applications from the ubiquitous and pervasive computing
domain are also characterized as context-aware applications. They
react not only to their internal state and user interaction but
also depend on the context they are processed in. In the past a
variety of context-models was subject of research. While early
models mainly addressed the modeling of context with respect to
one application or an application class, generic context models
are of interest since many applications can benefit from these.

Existing context models vary in the context they represent. While
some models take the user's current situation, e.g. "in a
meeting", into account, others model the physical environment,
i.e. locations. First steps towards a common understanding of
context have been published, mostly with respect to location,
identity, and time. In order to advance the state of the art, we
need to develop uniform context models, representation and query
languages, and reasoning algorithms that facilitate
interoperability of applications and context sharing.

This workshop's aim is to discuss fundamental issues in context
management and to identify widely applicable concepts, theories
and methods. This includes theoretical and practical issues
related to modeling and reasoning about context as well as
system-oriented issues related to the design and implementation
of context-aware systems.

CoMoRea will provide a forum for researchers to present and
discuss recent research results and ongoing work. A strong
emphasis is put on experiences with context representation and
the management of context information. The anticipated outcome of
the workshop is a clarification of context representation, its
management, and possible architectures based on the experiences
and discussions at the workshop.

  - Spatial and location models
  - Domain specific models
  - Properties of context models: consistency, accuracy, etc.
  - Integration of context models 
 - Context representation languages
  - Properties of representation languages: 
    expressiveness, interoperability, etc. 
 - Context reasoning algorithms
  - Properties of context reasoning algorithms: complexity,
    accuracy, etc. 
  - Context query languages
  - Context services: architectures, implementations, and 
    experiences 
 - Context capturing
 - Experience reports in the development of context-aware systems
   and applications, focussing on context modeling and reasoning 

Submissions
-----------------------------------------------------------------
Submissions of papers are solicited in the IEEE proceedings
format. Research papers must be original prior unpublished work
and not under review elsewhere. These can contain prior work if
clearly identified in the submission. Additionally a
comprehensive discussion of the taken approach, experiences, and
its assessment is expected. Submissions must not exceed 5 pages
in the IEEE proceedings format including references and
figures. Please send your submission in PDF format to Daniela
Nicklas <daniela.nicklas@informatik.uni-stuttgart.de>.

Accepted papers will appear in the combined PerCom 05 workshop
proceedings.
