| Abstract: | This paper introduces the notion of knowledge structuring by schemata. A schema is a chunk of knowledge which generalizes the idea of functional dependence between pertinent concepts (objects). The rules are closely related to the schemata. Moreover the schemata are organized in a hierarchical network which takes into account the relative importance of the concepts. Examples are given in the financial field and the consequences with regards to knowledge engineering are discussed. |
