US 6,171,109 B2 · Method for generating a multi-strata model and an intellectual information processing device

Abstract

The objective of this disclosure is to propose a method of designing an intelligent system assuring autonomy in problem solving to the largest extent. An architecture of a general purpose problem solving system and also a new modeling scheme for representing an object which may include human activity are discussed first. Then a special purpose problem solving system dedicated for a given problem is generated. It is extracted from a general purpose system using the object model as a template. Several new concepts are included in this disclosure to achieve this goal; a multi-level function structure and its corresponding knowledge structure, multiple meta-level operations, a level manager for building general purpose problem solving systems, a concept of multi-strata model to represent objects including human activity, and a method of extracting a special purpose system from a general purpose system and so on. This idea induces a very different view to computer systems from the conventional ones and systems designed according to this idea extend the scope of computer applications to a large extent, e.g., they can solve problems which require exploratory operations. In particular, it is important that this idea leads us to the concept of automatic programming instead of the conventional style of using computers.

A method for solving a problem in an intelligent information processing device having an intellectual function in a form of a structured knowledge base, the method comprising the steps of:

(a) defining a first level subject performing activities and a first level object to which the activities performed by the first level subject are to be directed, providing a request to define a problem at said first level with said first level object, and building a first level model from the first level object in response to a said first level subject's interest, said first level being corresponding to a first level of problem solving levels;
(b) defining a current level subject performing activities, a request for said current level subject and a current level object to which the activities performed by the current level subject are to be directed, said current level being corresponding to one level higher than a previous level of the problem solving levels at which the last model is built up and said current level object representing activities of said previous level subject during a building of the previous level model,
providing a task to be executed by the previous level subject with said current level object, and
building a current level model representing said current level object on the basis of an analysis of activities of said previous level subject;
(c) repeating the step (b) in order to cause the model to be hierarchical until a problem solving level at which a given problem is to be solved can be achieved;
and
(d) sequentially interpreting a request to each subject at a level of hierarchically structured levels from the upper most level to the lower level, identifying a type of problems corresponding to the request and executing a particular activity in response to the request.

#(1) Field of the Invention

#The present invention relates to a method for intellectually processing an information and an apparatus for carrying out the method and, in particular, a method for building knowledge base and an intellectual information processing device used in solving problems.

#The objective of this disclosure is to propose a new computer system which is truly intelligent and behaves like a person at problem solving. Here the term problem solving is used in a very wide sense to mean every activity to derive answer meeting given conditions in a given environment.

#1. INTRODUCTION

#The basic concept underlying the former part of the work presented here is similar with PROTEGE II, a knowledge-acquisition shell that uses problem-solving methods to derive the modeling of tasks, as described in A. R. Puerta, S. W. Tu, and M. A. Musen, Modeling Tasks with Mechanisms, International J. of Intelligent Systems, Vol. 8, 129-152, 1993. This system is rooted on the former research works such as J. McDermott, Preliminary Steps toward a Taxonomy of Problem Solving Methods, Automating Knowledge Acquisition for Expert Systems, (S. Marcus ed.) Kluwer Academic, 225-256, 1988 and M. A. Musen, Conceptual Models of Interactive Knowledge Acquisition Tools, Knowledge Acquisition, 1. 73-88, 1989. Those works, and the work presented in this disclosure too, build a method of problem solving for the given problem. There is however a big difference between them.

#The major difference is in the way of making the methods of problem solving and accordingly the modeling concept itself. In the works referred above the method is made by human knowledge engineer.
