The present invention relates to a method for answering a query (60) directed to a knowledge base. The basic idea underlying the present invention is to define a generic knowledge base with generic representatives (30) and generic rules (140). Generic representatives (30) represent the structure of objects (20) of the knowledge base. This enables generic rules (140), which represent the structure of the rules (50) of the knowledge base, to be applied to the generic representatives (30) without evaluating the corresponding objects (20) in a first step. In a second step, the inferred generic answers (90) (which are generic representatives (30)) can be used to restrict the original query (60) to objects (20) which have an appropriate structure. In a similar way, the generic representatives (30) applied for inference can be used to restrict the rules (50) of the knowledge base to objects (20) which have an appropriate structure. |
