Acquiring Knowledge for Linking Maintenance and Evaluation of Experience-based Information Systems

摘要: The value of most experience-based information systems tends to degrade with time. To keep the such a system, evaluation and maintenance is an essential. While monitors "value" over time, has preserve or improve this "value". Evaluation should not simply happen ad-hoc but systematically based on specific quality knowledge, which linked base evaluation. As jump-start for maintenance, respective knowledge be available right from start continuous operation. This paper describes how acquire develop during system buildup use operation combined human- computerbased maintenance. described approach been successfully applied in several projects. method illustrated examples two these projects as case studies.
