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.

[0266] 1. Construction of knowledge base

[0267] (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 subcategories, thus laying the foundation for directional data mining.

[0268] (2) Logical structure: In the corresponding domain of discourse, the rule base is classified into several rule sub-bases based on attributes, and each rule sub-base corresponds to the mining database.

[0269] The knowledge base is divided into a rule base and a fact base, and the two bases can be stored in the same table on the basis of attribute-based database construction. In the corresponding domain of discourse, the rule base is classified into several rule sub-bases based on attributes. Each rule subbase represents a class of properties. The rule sub-base is only a logical concept, that is, in the implementation, we do not explicitly store each rule sub-bas...

Abstract

The invention provides a KDK system integrated with R-type and S-type coordinators, belonging to the technical field of knowledge discovery in knowledge bases. A digital computer comprising a central processing unit and a memory, the memory of the digital computer stores a basic database and a synthetic knowledge base, and is characterized in that: the synthetic knowledge base is in the corresponding domain of discourse, and the rule base class is based on attributes It is transformed into 2-10 rule sub-bases, and each rule sub-base represents a class of attributes. The invention has the advantages that: the KDK* induction algorithm based on the facts and rules in the knowledge base is derived from the double-base fusion mechanism and the KDK structural model. Experiments show that: compared with the KDK algorithm based on facts and rules, the KDK mining algorithm based on Carnap and Cohen inductive logic is more effective and scalable.

Description

technical field [0001] The invention belongs to the technical field of knowledge discovery in knowledge bases, and in particular provides a KDK system integrated with R-type and S-type coordinators, 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 kno...
