Acquiring and Using Maintenance Knowledge to Support Authoring for Experience Bases

The value of a corporate information system such as a case-based reasoning system, experience base system, or lessons learned system tends to degrade with time. To keep the value of such a system, maintenance is an essential. Maintenance should not simply happen ad-hoc but systematically and based on specific maintenance knowledge. As a jump-start for maintenance, maintenance knowledge should be available right from the start of continuous operation. This paper describes how to acquire and develop suchmaintenance knowledge during buildup and how to use this knowledge during continuous operation for combined human- and computer-based maintenance.
