Supporting User-defined Activity Spaces

Activity spaces are usually task-specific and only common to a group of people who work together in a certain application domain. It is desirable to enable users to define and modify activity spaces according to their needs. However, many users are unable to use a pre-defined activity space correctly or incapable of formally defining an activity space. This work tries to solve these problems 1) by developing a flexible hypertext meta-model which can represent activity space semantics, 2) developing an example-based definition tool for users to create task-specific activity spaces, 3) providing intelligent aid in using these activity spaces, and 4) providing a flexible space for adopting existing and emergent patterns. A system (COWFISH) with the above components has been implemented and tested at GMD-IPSI. Examples and initial applications have shown that using the system users can easily define the schemata of many activity spaces and hyperdocuments. They can also create new activity...
