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

[0050] 1. Fact-based KDK modeling and mining algorithm

[0051] 1.1 Attribute-based knowledge base construction

[0052] 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:

[0053] (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.

[0054] (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.

[0055] (3) The construction of attribute-based knowledge base has also bee...

Abstract

The invention provides a KDK* system based on a double-base fusion mechanism, which belongs to the technical field of knowledge discovery in knowledge bases. A digital computer composed of a central processing unit and a memory, the memory of the digital computer stores a basic database and a synthetic knowledge base. The synthetic knowledge base classifies the rule base into several rule sub-bases based on attributes in the corresponding discourse domain, and each rule sub-base represents a class of attributes. The advantages of the present invention are: the structure of KDK* breaks through the original closed structure of KDK, organically integrates the database and knowledge base, KDD and KDK, greatly reduces manual participation, and improves the cognitive autonomy of the system sex. At the level of technical realization, they all have innovative value and can produce good social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of knowledge discovery in knowledge bases, and in particular provides a KDK* system based on a double-base fusion mechanism, specifically 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 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...
