Inference system having a frame structure and method of storing information therein

Claim 2

An inference system having an inference mode and a knowledge editing mode for conducting inference with an inherent effect by using a knowledge represented by a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said inference system comprising: mode selecting means for selecting one of said knowledge editing mode and said inference mode; first storing means for storing only information intrinsic to a first memory area of one of said frames into said one of said frames when said knowledge editing mode is selected by said mode selecting means; second storing means for storing into a second memory area of said one of said frames both information intrinsic to said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when said inference mode is selected by said mode selecting means; and memory clearing means for clearing information stored in said second memory area when a mode of the inference system changes from the inference mode to the knowledge editing mode.

Claim 3

A knowledge storing method for use in an inference system using a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said knowledge storing method comprising the steps of: storing only information intrinsic to a frame in the hierarchical structure into a first memory area of one of said frames when the inference system is in a knowledge editing mode; storing into said one of said frames both information intrinsic to a second memory area of said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when the inference system is in an inference mode; and clearing information stored in said second memory area when a mode of the inference system changes from the inference mode to the knowledge editing mode.

Claim 4

A knowledge storing method for use in an inference system using a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said knowledge storing method comprising the steps of: storing only information intrinsic to a frame in the hierarchical structure into a first memory area of one of said frames when the inference system is in a knowledge editing mode; storing into said one of said frames both information intrinsic to a second memory area of said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when the inference system is in an inference mode; and clearing information stored in said second memory area when a mode of the inference system changes from the inference mode to the knowledge editing mode.

Claim 5

An inference system having an inference mode and a knowledge editing mode for conducting inference with an inherent effect by using a knowledge represented by a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said inference system comprising: mode selecting means for selecting one of said knowledge editing mode and said inference mode; first storing means for storing only information intrinsic to a first memory area of one of said frames into said one of said frames when said knowledge editing mode is selected by said mode selecting means; second storing means for storing into a second memory area of said one of said frames both information intrinsic to said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when said inference mode is selected by said mode selecting means; first referencing means for referencing only said first memory area of said one of said frames when said knowledge editing mode is selected by said mode selecting means; and second referencing means for referencing only said second memory area of said one of said frames when said inference mode is selected by said mode selecting means.

Claim 6

An inference system having an inference mode and a knowledge editing mode for conducting inference with an inherent effect by using a knowledge represented by a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said inference system comprising: mode selecting means for selecting one of said knowledge editing mode and said inference mode; first storing means for storing only information intrinsic to a first memory area of one of said frames into said one of said frames when said knowledge editing mode is selected by said mode selecting means; second storing means for storing into a second memory area of said one of said frames both information intrinsic to said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when said inference mode is selected by said mode selecting means; first referencing means for referencing only said first memory area of said one of said frames when said knowledge editing mode is selected by said mode selecting means; and second referencing means for referencing only said second memory area of said one of said frames when said inference mode is selected by said mode selecting means.

Claim 7

A knowledge storing method for use in an inference system using a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said knowledge storing method comprising the steps of: storing only information intrinsic to a frame in the hierarchical structure into a first memory area of one of said frames when the inference system is in a knowledge editing mode; storing into said one of said frames both information intrinsic to a second memory area of said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when the inference system is in an inference mode; referencing only said first memory area of said one of said frames when said knowledge editing mode is selected by said mode selecting means; and referencing only said second memory area of said one of said frames when said inference mode is selected by said mode selecting means.

Claim 8

A knowledge storing method for use in an inference system using a plurality of frames in a hierarchical structure which have a relationship of a parent frame being higher in the hierarchical structure than a child frame thereof, said knowledge storing method comprising the steps of: storing only information intrinsic to a frame in the hierarchical structure into a first memory area of one of said frames when the inference system is in a knowledge editing mode; storing into said one of said frames both information intrinsic to a second memory area of said one of said frames, and information inherited by at least said one of said frames from frames higher in the hierarchical structure than said one of said frames when the inference system is in an inference mode; referencing only said first memory area of said one of said frames when said knowledge editing mode is selected by said mode selecting means; and referencing only said second memory area of said one of said frames when said inference mode is selected by said mode selecting means.
