WORKSHOP GOALS

This workshop addresses facilitation of collaborative work by
context-adaptive techniques. Context-based adaptation can support  
users in
a variety of ways, e.g., by offering the tools most appropriate for a
certain type of collaboration, by providing templates for artifacts to  
be
produced, or by filtering content relevant for a joint activity. While
adaptive (single) user interfaces have been an area of research for
considerable time adaptation for collaboration is far less investigated.

The notion of context in collaborative work raises a variety of
interesting research issues. So far, attempts to structure and classify
the multi-faceted concept of context have been mainly directed at
individual, rather than cooperative usage scenarios. The importance of
common ground, e.g., for electronically mediated communication has been
pointed out repeatedly, but theoretical concepts have hardly been
translated into explicit models or concrete adaptation mechanisms. We  
also
see a major challenge in integrating 'exogenous' physical context such  
as
location, time or device used with 'endogenous' context factors such as
the users' roles, topical interests, experience profiles or used
collaboration tools. For this purpose, integrated, coherent
representations of these context aspects will be needed, making them
explicit and exploitable by adaptation mechanisms. Ontology-based  
context
models promise to provide coherent representations but are still in  
their
initial stages. Other important issues are how to combine individual
contexts into shared collaborative contexts, and how to combine
folksonomy-based bottom-up approaches with the benefits of  
standardization
that ontologies traditionally provide. Finally, it is largely unresolved
how to define effective and acceptable adaptations for groups. While  
there
has been a considerable amount of research into supporting co-located or
remote meetings, more general issues of supporting collaboration by
adaptations are still open.

The workshop aims at identifying and structuring context factors for
collaborative work, trying to elaborate a generalized notion of context
including physical and tool-related aspects, common ground related to
content and process of the collaboration, and other factors. We will  
also
discuss strategies and methods for making these context aspects explicit
by representing them through suitable models, e.g., by ontological  
models
of cooperative context. These models will serve as input for discussions
on how to manage and use such context in real-world scenarios. These
activities will serve laying the groundwork for an initiative to build a
shared context ontology for this area.

TOPICS OF INTEREST

An initial list of research issues discussed at the workshop comprises  
the
following questions:
- How can the multi-faceted concept of context be structured and
classified for cooperative situations?
- What are methods for integrating 'endogenous' physical context with
'endogenous' context factors such as the users' roles, activities,  
topical
interests or experience profiles?
- How to combine individual contexts into group contexts?
- What are suitable models and techniques for representing context for  
the
purpose of adapting cooperation support systems? Is there a perspective
for a shared context ontology for cooperative work?
- What are effective and acceptable adaptations at the interaction, tool
or content level we can implement in systems used for collaboration?

CALL FOR PARTICIPATION

Context plays an increasingly important role to adapt systems to users'
needs and to make access to large information spaces more efficient.  
Yet,
in the area of collaborative work the potential of context-based
adaptation of IT systems has so far not been investigated and  
exploited to
a sufficient extent. There is a lack of methods that take into account  
the
manifold aspects of context such as physical, activity-based, thematic  
or
social context in an integrated fashion.

The workshop aims at identifying and structuring context factors for
collaboration, trying to elaborate a generalized notion of context for
this field. We will discuss strategies and methods for making these
context factors explicit by representing them through suitable models,
e.g., by ontological models of cooperative context. A potential  
outcome is
to provide the groundwork for an initiative to build a shared context
ontology for cooperative work. A further goal is to collect and analyze
methods for managing and using context in real-world scenarios,  
including
combinations of folksonomy- and ontology-based approaches.

Persons interested in participating should submit a 2-page proposal
describing their background with respect to the workshop theme, their
proposed contribution and an initial reaction to a number of research
issues published at the workshop website (http://caicoll.org). Proposals
should be sent by e-mail to [log in to unmask] Upon acceptance,
participants will be asked to provide an extended position paper of 5
pages four weeks prior to the workshop which will be distributed to
participants. Workshop results will be summarized on the website.
Depending on the submissions received we plan to publish the workshop
results to a wider audience, e.g. as a special journal issue.
