organizational memory
First Link
The paper starts with a discussion of the roles an organisational memory (OM) should play and what kind of knowledge should go into it. We then identify two kinds of integration problems. The first one is concerned with integrating the know ledge bases of different knowledge-based systems employed in an organisation int o one physically or virtually unified knowledge base which is to be considered a s part of the organisation's OM. The second problem concerns the integration of several representations of the same knowledge with different degrees of formalization, ranging from formally represented knowledge via semi-structured text to p lain text. This is an issue because formally represented knowledge, e.g. company regulations, often also exists in textual form, and both representations are ne eded for different kinds of tasks. It is argued that the two integration problem s mentioned can only be solved by making use of a high-level language whose repr esentation constructs are on the conceptual level (in the sense of Brachman) and which covers all representational needs. We argue that such a language can be made easy to use despite its being extremely comprehensive if the representationa l ontology underlying its constructs is represented explicitly.
