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.

Embodiment Construction

[0034] 1. Fact-based KDK modeling and mining algorithm

[0035] 1.1 Attribute-based knowledge base construction

[0036] In the KDK system, an attribute-based knowledge representation method is selected, and its final form is a production rule, which is mainly based on the following considerations:

[0037] (1) In the next step of work, the results of KDK will be connected with the database and the KDD process, which requires that an interface must be left for the coordination of the knowledge base and the database. The attribute-based database building method makes the knowledge base and database similar in structure, which is convenient for coordination.

[0038] (2) The database building method based on attributes can effectively borrow the existing functions of the database, facilitate the storage of large-capacity knowledge, and solve the problem of small capacity of the current knowledge base.

[0039] (3) The construction of attribute-based knowledge base has also bee...

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 general induction algorithm based on facts and rules in knowledge base are derived from structure module of bi radical syncretized mechanism and KDK system syncretized to R type synchronizer. The experiment indicates that comparing with KDK algorithm based on facts and rules, general induction algorithm based on Karlnapu and kirn inductive logic possesses higher validity and extensibility.

Description

technical field [0001] The invention relates to the technical field of knowledge discovery in knowledge bases, in particular, it provides a KDK system integrated into an R-type coordinator, specifically a construction method of a novel 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 accurate, 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 knowledge engineering and machine learning. In the past ten years since its emergence, the mainstream of research has been knowledge discovery based on databases (KDD). However, knowledge discovery based on knowledge base, that is, how to further generate new deep-level knowledge from the existing massive knowledge base and expand it into the knowledge ba...
