Abstract

Abstract A knowledge system incorporating a graphic display which allows the user, at any time during the use of the system, to select a part of one of the displayed chucks of knowledge (or the only one) and to perform a command which will automatically display the link(s) of a certain nature to other chunks of knowledge. The latter chunks are thus dynamically added to the drawing. The same function can be applied recursively in any direction until no further knowledge chunks are to be displayed. The resulting drawing can be larger than the display screen and graphic window or screen scrolling mechanisms allow one to move from one area of the overall graph to another. A series of functions allow the user to remove a link and its corresponding chunk(s) from the display, to create a new group of chunks (a group is defined as a set of chunks linked together graphically), and to modify the parameter of the display as a function of the nature of the links, the current state of each item (chunks and their elements, links) and the overall state of the system at the time of display.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 112 words
A knowledge system comprising a programmed computer, memory means for storing a knowledge base, said knowledge base including datum, rules which interconnect the datum to create hypotheses, and wherein the interrelationships between the various datum and the rules constitute a network of interrelationships; display means for displaying the network of interrelationships as stored in the memory means; user information input means for allowing the user of the system to input data, rules and to change the data or rules currently stored in the memory means; and means, including the display means, connected to the computer for interactively displaying the network of interrelationships visually and interactively with the changes made by the user.
Claim 2
Dependent Claim 112 words
A knowledge system comprising a programmed computer, memory means for storing a knowledge base, said knowledge base including datum, rules which interconnect the datum to create hypotheses, and wherein the interrelationships between the various datum and the rules constitute a network of interrelationships; display means for displaying the network of interrelationships as stored in the memory means; user information input means for allowing the user of the system to input data, rules and to change the data or rules currently stored in the memory means; and means, including the display means, connected to the computer for interactively displaying the network of interrelationships visually and interactively with the changes made by the user.
Claim 3
Dependent Claim 40 words
A knowledge system as recited in claim 1 wherein the means for interactively visually displaying the network of interrelationships includes user controlled means for selecting the amount of the network of relationships to be simultaneously displayed on the display means.
Claim 4
Dependent Claim 51 words
A knowledge system as recited in claim 1 further comprising printing means connected to the computer and wherein the means for interactively visually displaying the network of interrelationships includes user controlled means for causing the printing means to print out a diagram of the network of interrelationships selected by the user.
Claim 5
Dependent Claim 58 words
A knowledge system as recited in claims 1 or 2 wherein the computer comprises an operating system and an expert applications system including an expert system kernel, a rule compiler, an inference engine, and a dynamic browsing display means which allow the user to visually browse through the network of interrelationships by displaying them on the display means.
Claim 6
Dependent Claim 60 words
A knowledge system as recited in claim 4 wherein the dynamic browsing means allows the user, at any time during the use of the system, to select a part of one of the displayed interrelationships and to then automatically display on the display means other network interrelationships of a selected nature to the user selected part of the network interrelationship.
Claim 7
Dependent Claim 66 words
A knowledge system as recited in claim 1 wherein the network of interrelationships stored in the memory means is larger than can be displayed at any one time by the display means and wherein the computer further comprises means for causing the display means to scroll a graphic window through the network of interrelationships stored in the memory means under the interactive control of the user.
