Integrated Media Mining for Virtual Workspace Design

Supporting virtual collaboration can be complex and timeconsuming exercise. One of the key components in setting up virtual collaboration is the design of the virtual workspace as a coherent medium to support the activities involved in collaborative project development. The availability of information about virtual collaboration in virtual workspaces, in the form of action patterns, offers opportunity for utilization of such information and its future reuse. This paper presents a new approach for supporting design and redesign of virtual workspaces, based on combining integrated data mining techniques for refining the lower level models with a reverse engineering cycle to create upper level models. The methodology is based on the combination of a new model of vertical information integration related to virtual collaboration (the Information Pyramid of Virtual Collaboration), which encompasses information about objects and actions that make up action patterns at different levels of granularity. The approach allows comparison at all levels of the initial model of a process built based on the topdown requirements engineering approach with the model built from the actual workspaces by the proposed reverse engineering cycle.
