Problems solved by technology

[0008] The current research on knowledge bases at home and abroad only stays in the aspects of eliminating contradictions, redundancies, reasoning chain loops, and completeness detection of knowledge bases, but there is no systematic knowledge discovery (KDK) based on facts and rules in knowledge bases.

[0262] 1. Construction of the knowledge base

[0263] (1) The principle of knowledge base construction: based on attributes, its characteristic is to facilitate the formation of the corresponding relationship between knowledge nodes and data sub-categories, thereby laying the foundation for directional data mining.

[0264] (2) Logical structure: In the corresponding domain, the rule library is classified into several rule sub-libraries based on attributes, and each rule sub-library corresponds to the mining database.

[0265] The knowledge base is divided into a rule base and a fact base. Based on the establishment of a base based on the principle of attributes, these two bases can be stored in the same table. In the corresponding domain, the rule library is classified into several rule sub-libraries based on attributes. Each rule sub-library represents a type of attribute. The rule sub-library is only a logical concept, that is, in the implementation, we do not explicitly store ...

Abstract

Belonging to technical area of knowledge discovery of knowledge base, the disclosed system includes digital computer composed of CPU and storage. Storage of computer stores basic database and synthesized knowledge base. Characters are that within relevant domain, rule base is apperceived as 2-10 rule sub bases based on attributes; each sub base represents a generic attribute. Advantages are that KDK* induction algorithm based on facts and rules in knowledge base is derived from bi radical syncretized mechanism and KDK structure module. The experiment indicates that comparing with KDK algorithm based on facts and rules, the KDK mining algorithm based on Karlnapu and kirn inductive logic possesses higher validity and extensibility.

Description

Technical field [0001] The invention belongs to the technical field of knowledge discovery in the knowledge base, and in particular provides a KDK system incorporating R-type and S-type coordinators, and specifically is a construction method of a new type of knowledge discovery system. Background technique [0002] Knowledge Discovery in Knowledge-base (KDK) refers to discovering new knowledge from the knowledge base, or refining and revising existing knowledge to make it more precise, complete and concise. KDK is a new and challenging research direction in the field of knowledge discovery. [0003] Knowledge discovery is an important branch of the field of knowledge engineering and machine learning. In the more than ten years since its emergence, the mainstream of research has been Knowledge Discovery Based on Database (KDD). Knowledge discovery based on the knowledge base, that is, how to further generate new deep-level knowledge from the existing massive knowledge base and exp...
