Knowledge processing method and device based on multilayer network space knowledge representation

Abstract

The invention relates to a knowledge processing method and device based on multilayer network space knowledge representation. The method comprises the steps of constructing multilayer network space knowledge representation of a multilayer structure from top to bottom, wherein the multi-layer structure comprises a macroscopic layer, an implementation layer, an attribute layer, a resource layer anda relationship layer from top to bottom; for each multi-layer structure, according to the knowledge of the corresponding subject field, extracting the ontology corresponding to the multi-layer structure and the spatial relationship between the ontologies; constructing a six-tuple knowledge representation for the multi-layer network space knowledge representation, wherein the six-tuple knowledge representation comprises a head entity, a relationship, a tail entity, a time concept, a space concept and a processing operator; and carrying out knowledge processing on the multilayer network space knowledge representation according to the six-tuple knowledge representation. By adopting the method, the multi-path interaction and complex association relationship between cross-domain elements of thenetwork space can be comprehensively represented.

Description

technical field [0001] The present application relates to the technical field of knowledge graphs, in particular to a knowledge processing method and device based on multi-layer cyberspace knowledge representation. Background technique [0002] With the rapid development of network information technology, cyberspace has become a new living space created and developed by human beings. All countries in the world are aware of the important strategic significance of cyberspace territory, calling it the successor of "land, sea, air and sky". The fifth strategic space after that. The key to maintaining cyberspace sovereignty and guarding important locations in cyberspace is to have a thorough perception of the basic elements and dynamic laws of cyberspace, and at the same time dig out the key information contained in it and predict its changing laws. However, cyberspace is a complex giant system with heterogeneous, dynamic, and multi-dimensional characteristics. It exhibits extre...
