The EXTERNAL experience on system and enterprise integration

2004 , Wang, W. , Lillehagen, F. , Karlsen, D. , Johnsen, S.G. , Krogstie, J. , Rubart, J. , Haake, J.M.

The overall objective of the EXTERNAL project is to make it easier for business partners to form and operate extended enterprises as dynamic networked organisations. From a technical perspective, EXTERNAL, is largely a system integration project, in which a set of complementary tools are integrated into a Web-based knowledge sharing infrastructure to provide a comprehensive set of services for EE engineering and operation. As a result from our evolving understanding, we shifted from system integration and an Information and Communication Technology (ICT) infrastructure towards enterprise integration and an intelligent Extended Enterprise infrastructure based on Active Knowledge Models.

A cooperative visual hypermedia approach to planning and conducting virtual meetings

2002 , Wang, W. , Haake, J.M. , Rubart, J.

Most distributed meeting support systems focus on meeting management and audio/video communication mechanisms. They provide little support for a flexible meeting process and a shared information space with structure- rich visual artifacts. A cooperative visual hypermedia system is developed to provide visual hypermedia artifacts for team members to manipulate in a distributed meeting. The visual hypermedia system is a hypermedia-based drawing system that integrates visual hypermedia artifacts and structures found in multiple hypertext domains. In addition, the visual hypermedia is integrated with process support for flexible meeting control and for easy setup of audio/video and application sharing communication channels. A use case is presented, which shows that using the cooperative visual hypermedia, distributed teams can perform many kinds of meetings, in the meantime, enjoying dedicated support for the planning, control, information management, and follow-up activities of a distributed meeting.

Hypermedia-based support for cooperative learning of process knowledge

2000 , Wang, W. , Haake, J.M. , Rubart, J. , Tietze, D.A.

The WWW makes learning materials widely accessible and provides an environment where people can learn across time and space. However, the simple read-only information structure on the Web provides little or very limited guidance to learners, especially when they want to learn how to do something through interaction with computers and other people. We suggest overcoming the problem by introducing a graphical hypermedia-based process representation and a cooperative process enactment support. The hypermedia-based process structure is accessible on the WWW. It contains a rich set of associated materials with which people can seamlessly interact while they are systematically carrying out the process they are learning under the guidance of computers or tutors. A hypermedia-based process support system and two use cases are presented. The use cases show that such a system can not only provide traditional learning support, but also offers novel cooperative hypermedia based support for the learning of process knowledge.

A meta-modeling environment for cooperative knowledge management

2003 , Rubart, J. , Wang, W. , Haake, J.M.

Knowledge management (KM) systems usually focus on specific tasks. In this paper, we identify B- and C-level improvement activities for cooperative KM based on Engelbart's ABC model of organizational improvement. We present a cooperative meta-modeling environment, which is based on cooperative hypermedia. It supports the configuration of domain-specific knowledge schemas and their ad-hoe adaptation with special consideration of behaviors.

Supporting cooperative learning in distributed project teams

2002 , Wang, W. , Haake, J.M. , Wessner, M.

The trend towards rapid development and globalization of business activities requires business teams to carry out their projects in a distributed environment. Changes in the environment as well as in the team require these teams to continuously learn and to learn new knowledge and skills and to adapt their work processes. In such a distributed working and learning setting, team members need a shared information space to interact with various information resources and to coordinate and communicate to harmonize their actions. In our approach we combine work (i.e. the definition and execution of work processes) and learning (i.e. the learning and practicing of work processes) of distributed project teams. A cooperative visual hypermedia environment has been developed which offers support for cooperative work and learning. This visual environment provides various real-time dynamic views of the underlying work processes. These views help team members to identify situations that trigger a need for cooperative learning. By combining the work and the learning processes, this environment offers new possibilities for cooperative learning in distributed project teams such as process simulation, guided tours by experts through process descriptions and best practice examples, and cooperative roleplay for practicing work processes.
