Abstract

We need to use dynamic knowledge organization approaches in order to facilitate effective access and use of domain knowledge. Although there are many approaches to knowledge organization available, it is a challenge to systematically organize evolving domains, because it is not feasible to rely only on humans to create relationships among individual knowledge sources. Additional problems arise because knowledge may not be consistently and completely described, and quality control may not always be in place in distributed knowledge environments. In this article we describe a generic approach to knowledge organization by using systematic knowledge management and applying knowledge-discovery techniques. We use a case-based reasoning system, called TA3, as a core component for knowledge management. Application of symbolic knowledge-discovery component of TA3 supports three main tasks: system optimization, knowledge evolution and evidence creation. To explain advantages of this approach, we use our experience from biomedical domains
