In an inference system, an inference mode and a knowledge editing mode can conduct inference with an inherent effect by using knowledge represented by frames in a hierarchical structure, the frames having a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof. Such an inference system includes a mode determining section for selecting the knowledge editing mode or the inference mode, a storage area for storing only information intrinsic to a frame in the hierarchical structure into the frame when the knowledge editing mode is selected by the mode determining section, and a storage area for storing into the frame both information intrinsic to the frame and information inherited by the frame from frames higher in the hierarchical structure than the frame when the inference mode is selected by the mode determining section.
