Abstract

An information processing system which has a portion for storing metaknowledge and a portion for utilizing the metaknowledge stored in said storage portion. In newly acquiring knowledge, the utilizing portion utilizes the metaknowledge stored in said storage portion. A knowledge input prompting function that works to utilize the metaknowledge makes reference to metaknowledge in the metaknowledge memory function, looks for knowledge that is lacking, and prompts the input thereof. An input knowledge checking function which also utilizes the metaknowledge makes reference to metaknowledge to look for constraint related to the input knowledge, and evaluates whether it is satisfied or not. These utilization functions make it possible to keep the justification and consistency of knowledge acquired.

Claims

1. In an information processing system which has processing means, memory means, and input/output means, a knowledge information processing system comprising:

memory means for storing meta-knowledge including a knowledge structure information of an alterable part and unalterable part necessary for acquiring knowledge; and

a processing means for acquiring new knowledge utilizing said meta-knowledge stored in said memory means.

2. The knowledge information processing system according to claim 1, further comprising:

an acquired knowledge storing means for storing knowledge to be acquired, and wherein said processing means further includes means for requesting an input of a specific knowledge in accordance with said stored meta-knowledge and said stored knowledge.

3. The knowledge information processing system according to claim 1, further comprising:

an acquired knowledge storing means for storing knowledge to be acquired, and

a knowledge inputting means, and wherein

said processing means further includes means for evaluating correctness of knowledge inputted by said inputting means by reference to said meta-knowledge stored and said knowledge stored.

4. In an information processing system which has processing means, memory means, and input/output means, a knowledge information processing system comprising:

knowledge defining means for defining knowledge information to specify data structure of a result of an inference on the basis of inputted information by interaction with said input/output means;

rule defining means for defining rules to renew a result of an inference; and

updating means for forming said result of an inference from knowledge defined from the knowledge defining means to specify a data structure, and rules defined by said rule defining means to update said result of an inference.

5. A knowledge information processing system according to claim 4, wherein the updating means includes means for generating updates in an event-driven manner.

6. In an information processing system which has processing means, memory means, and input/output means, a knowledge information processing system comprising:

memory means for storing meta-knowledge for acquisition of knowledge defined by a knowledge structure with an unalterable portion and an alterable portion; and

processing means for acquiring new knowledge in accordance with meta-knowledge stored in said memory means.

7. The knowledge information processing system according to claim 6, wherein said meta-knowledge is further defined to include information of procedures for acquiring knowledge to alter said alterable part.

8. In an information processing system which has processing means, memory means and input/output means, a knowledge information processing system comprising:

means for defining a manual for a format of a slip and book and for a sheet adapted to said format used in an office environment, on the basis of information input by interaction of said input/output means;

means for forming said sheet from said format to renew a value of said sheet; and

means for renewing said sheet in an event-driven manner in accordance with reference to said manual.

9. The knowledge information processing system according to claim 8 further comprising:

means for defining meta-information of said format and said manual;

means for updating said sheet in an event-driven manner by making reference to said manual; and

wherein the processing unit includes means for defining said format and said manual references meta-information in said meta-information defining means.

10. A knowledge information processing method in an information processing system which has processing means, memory means and input/output means comprising:

a step for storing meta-knowledge having an alterable portion and unalterable portion in said memory means;

an

a processing step for acquiring new knowledge utilizing said meta-knowledge stored in said memory means.

11. A knowledge information processing method in an information processing system which has processing means, memory means and input/output means comprising the steps of:

defining knowledge information to specify data structure of a result of inference on the basis of inputted information by interaction of said input/output means;

defining rules for renewing result of inference; and

forming said result of inference from said defined knowledge information to specify data structure and said rules to update said result of inference.

12. The knowledge information processing method of claim 11, further comprising the steps of:

storing knowledge to be acquired; and

requesting an input of a specific knowledge by referring to said meta-knowledge stored and said knowledge stored.

13. The knowledge information processing method according to claim 11, further comprising:

a knowledge storing step for storing knowledge to be acquired; and

a knowledge inputting step, and said processing step further having a step for evaluating correctness of a knowledge inputted by said inputting step by reference to stored meta-knowledge and stored knowledge.

14. A knowledge information processing method in an information processing system which as processing means, memory means, and input/output means comprising the steps of:

storing meta-knowledge for acquisition of knowledge having knowledge structure information of a part which should not be altered after defined and of an alterable part; and

acquiring new knowledge utilizing stored meta-knowledge.

15. The knowledge information processing method of claim 14 further comprising the step of acquiring knowledge to alter said alterable part of said meta-knowledge.
