Interactively building and executing knowledge base system with knowledge variables

摘要

A knowledge base system for building a knowledge base. The knowledge base system includes an interface device that receives said knowledge base by a user, and a generating device that generates a program based upon the knowledge base. The interface device includes a field that stores an output knowledge variable, input and local fields that store knowledge variables for operating the output knowledge variables, and a field that stores a computing equation of declarative representation that utilizes knowledge variables using operands as other knowledge variables. The generating device includes a translating device that translates the computing equation of declarative representation into a computer program, a retrieving device that retrieves a dependence of the output knowledge variable on other knowledge variables, and a setting device that sets an execution sequence of the computer program for instructing an input request and computation with reference to the dependence, in which the knowledge base system includes at least one alternative solution.
