Program scheduleProgram scheduleGroup editors are themselves useful tools
for multimedia coauthoring and have been used as an effective model and vehicle
of a wide range of collaborative applications. Within the CSCW field,
collaborative editing systems have been developed to support a group of people
editing a document collaboratively over the computer network. These systems can
be used in a wide range of advanced computing application areas, including
collaborative writing, collaborative CAD and CASE. The major benefits of
collaborative editing include reduced task completion time and distributed
collaboration. On the other hand, the challenges that it raises are many,
ranging from the technical challenges of maintaining consistency to the social
challenges of supporting group activities and conventions across many different
communities.
Collaborative editing is faced with a set of
social issues that support and improve the team work. For example, voice
communication can help people working together in real time over an interactive
workspace. Flexibility should be offered to support different forms of
collaborative activities such as melding of synchronous and asynchronous work.
The impact of organizational roles on the participants in editing is another
social challenge for group editors.
Technical issues such as concurrency control
algorithms have been addressed also in other fields such as databases and
distributed systems. However, unlike most distributed applications, groupware
demands that we consider the role of the human when selecting the concurrency
control schemes. Consequently, classical approaches cannot be applied outright
to groupware due to their effect on the user interface. The novel techniques
proposed for collaborative editing such as operational transformation,
multi-versioning, optional locking, group undo can bring new insights into the
design of other multi-user applications including Internet-based multi-player
games, collaborative virtual environments, and mobile computing. Other issues
critical for the design of groupware applications include security and access
control.
This workshop builds on the success of similar workshops at Group'99, CSCW'00, Group'01, CSCW'02, ECSCW'03, and CSCW'04. The main focus of the Group'99 workshop was consistency maintenance algorithms. Then, the CSCW'00 workshop included more issues of usability. Further, the Group'01 workshop focused on the people and organizational issues in developing collaborative documents. The CSCW'02 workshop concentrated on usage scenarios of collaborative editing. The main topic of the ECSCW'03 workshop was the integration of collaborative editors into general information or application infrastructure. The main topic of the CSCW'04 workshop was the enhancement of the well-known existing single user systems with collaborative editing techniques. The objective of the proposed workshop is to apply/expand collaborative editing technologies to broader areas/applications.
We invite submissions addressing issues related to collaborative editing. Interesting topics include but are not limited to the following:
Social aspects of collaborative editing
Organizational and workflow requirements and issues associated with collaborative editing
Usability studies of group editors and human factors
Infrastructure of collaborative editing systems
Innovative techniques for adapting single-user editing systems for collaboration
Concurrency control and consistency maintenance in group editors
Application of group editing techniques and algorithms in distributed applications
The goal of this workshop is to bring together researchers from various backgrounds having interest in collaborative editing. We invite contributions from experts in the area of distributed computing, information systems, human-computer interaction, and social science. Furthermore, we also encourage participation from users who are in need of large systems offering facilities for collaborative editing to discuss their requirements. While each participant is encouraged to submit a paper, other participants will be accepted on a space available basis.
Participants should submit a 4 to 8 page working paper pertaining to their research area for presentation and discussion during the workshop. Papers should be formatted using the standard ACM SIGCHI format and should include an abstract of no more than 150 words. Accepted papers will be published in a special issue of Collaborative Computing in IEEE Distributed Systems Online. All submissions should be sent to Dr. Haifeng Shen at ashfshen@ntu.edu.sg by October 9, 2005.
Paper submission: Sept 10, 2005 October 9, 2005.
Notification of acceptance: Sept 27, 2005 October 26, 2005.
Workshop: November 6, 2005.
