3 Terms and Definitions

The terms and definitions defined in GB/T 42131-2022, as well as the following terms and definitions, apply to this document.

3.1 Ontology

A model that represents entity types and the relationships between entity types, as well as entity type attribute types and their associations.

Note. The goal is to capture knowledge in the relevant domain, identify commonly accepted vocabulary within that domain, describe the semantics of entities through relationships between them, and provide insights into...

A shared understanding of the knowledge in this field.

[Source. GB/T 42131-2022, 3.8, with modifications]

3.2

Application areas of standardization activities are categorized by professional technology, industry, or social management scope.

Examples include fields such as medical standards and petroleum standards.

The classification system has been expanded.

3.3

Formalizing the ontology of the standard domain knowledge system.

Note. This refers to a model of entity type declarations in a standard domain, the relationships between entity types in a standard domain, and the attributes and axioms of entity types in a standard domain.

3.4 entity

An independent object.

Note. In the context of this document, it is used to refer to things in standardized documents, such as entities like "terms," "chapter," and "article."
