Problems solved by technology
Such knowledge base reasoning technology cannot realize the expansion of reasoning semantics as needed, and is also fixed in the scheduling of rules, and cannot optimize the scheduling order of rules according to changes in rules / rule sets
Therefore, the existing knowledge base reasoning technology has a small scope of application, poor flexibility and low reasoning efficiency
[0006] In addition, the existing knowledge base reasoning technology is prone to problems such as insufficient memory and high hard disk overhead, which will also lead to reduced reasoning efficiency

Abstract
The present invention discloses a data processing method, a knowledge base reasoning method and related devices, wherein the data processing method includes: obtaining the rule dependency for determining the scheduling order of each rule in the knowledge base reasoning process in the following manner: Selecting data from the knowledge base to form a first data set; reasoning the first data set according to the rules of the knowledge base; determining the rule dependencies according to the reasoning results of each rule and corresponding input data. By adopting the invention, the application scenarios and flexibility of the knowledge base reasoning technology can be improved, the efficiency of rule execution and the overall reasoning performance can be improved.
Description
technical field [0001] The present invention relates to the field of data processing, and more specifically, to a data processing method applied to knowledge base reasoning, a knowledge base reasoning method and related devices. Background technique [0002] The knowledge in the knowledge base is divided into two categories: ontology and fact. A triplet is used to represent (subject, predicate, object), abbreviated as (s, p, o). Wherein the fact refers to a basic description in the real world or the virtual world, such as "Yao Ming's wife is Ye Li" can be expressed as (Yao Ming, wife, Ye Li) by a triple. Ontology is an abstraction of facts, including concepts, attributes, relationships between concepts, relationships between attributes, and constraints on concepts and attributes. For example, define the concepts "person" and "athlete", define the attributes "wife", "husband", define the relationship between concepts (athlete, subclass (subClassOf), person), and define the ...
