PublicationThe 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.

PublicationVisualizing and interacting with hypermedia-based process-centric enterprise models( 2003)Wang, W.Interoperability and cross-fertilization of multiple hypermedia domains are relatively new concerns to the open hypermedia and structural computing community. Recent work in this area has explored integrated data models and component-based structural service architectures. This paper focuses on the user interface aspects relating to client applications of the structural services. It presents an integrative design of a graphical hypermedia user interface for hypermedia-based process-centric enterprise models. An enterprise model covers various important perspectives of an enterprise (such as processes, information, organization, and systems). In this paper, examples are given to show that these perspectives are presented better using a mixture of hypermedia structures found in several hypermedia domains. The visualization and interaction design for such hypermedia-based enterprise models integrates many features found in navigational, spatial, taxonomic, workflow and cooperative hypertext domains. A use case is provided to show that client applications based on this design allow users to see and interact with an enterprise model from multiple perspectives. In addition, some' initial user experience is also reported.
PublicationA 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.

PublicationSupporting 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.

PublicationA 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.
