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.
