Embodiment

[0063] Embodiment: The construction method and device of the domain knowledge map based on the core ontology of the middle layer, refer to Figure 4 , The construction device of the domain knowledge graph based on the middle layer core ontology includes a domain core ontology construction module 110, a domain ontology module construction module 120, a link processing module 130, a domain knowledge graph acquisition module 140 and a maintenance and upgrade module 150. The domain core ontology construction module 110 is used to construct a domain core ontology based on the top-level ontology of General Formal Ontology (General Formal Ontology), that is, the middle-level core ontology. The domain ontology module construction module 120 is used to construct the domain ontology module from bottom to top according to the general formal ontology to form a modular domain ontology. The link processing module 130 is used to perform link processing on the middle layer core ontology and t...

Abstract

The invention discloses a domain knowledge graph construction method and device based on an interlayer core ontology, and belongs to the technical field of knowledge graphs, and the construction method comprises the following steps: S1, constructing a domain core ontology based on a general formal ontology top layer ontology, namely the interlayer core ontology; S2, constructing a domain ontologymodule from bottom to top according to the general formal ontology to form a modular domain ontology; S3, linking the interlayer core ontology and the modularized domain ontology; S4, forming a domainknowledge graph with a unified semantic specification and a general formal ontology top layer framework in a module integration mode; and S5, maintaining and upgrading the domain knowledge graph, fusing a top-down mode and a bottom-up mode, and providing a knowledge graph modeling method with a unified semantic specification based on a top-layer ontology framework.

Description

technical field [0001] The present invention relates to the technical field of knowledge graph, and more specifically, it relates to a method and device for constructing a domain knowledge graph based on an intermediate core ontology. Background technique [0002] A knowledge graph is a knowledge base expressed in the form of a semantic network, which describes concepts, entities, events and their relationships in the objective world in the form of a graph. Among them, the concept refers to the conceptual representation of objective things formed by people in the process of understanding the world, such as people, animals, organizations, etc.; entities are specific things in the objective world; events are observable or perceivable in the objective world. Certain processes or activities; relationships describe the objectively existing associations between concepts, entities, and events. The graph here refers to the graph in the data structure, which is composed of nodes (no...
