Scope

GB/T 42131-2022 is the English-translated version of 人工智能知识图谱技术框架.

GB/T 42131-2022 gives the conceptual model and the technical framework for knowledge graphs in artificial intelligence, organised around four roles.

For the knowledge graph supplier, the integrator, the users and the ecosystem partners it specifies the inputs, the outputs, the main activities and the quality requirements: the supplier's activities run from knowledge representation, modelling, acquisition, fusion and storage to knowledge computing, traceability, evolution and quality assurance, and the integrator's from requirements analysis and system design through integration and application development to system maintenance.

Its clause 8 separates knowledge users, knowledge maintainers and knowledge providers. It defines knowledge, entity, entity type, knowledge element, knowledge graph and knowledge unit, and states that it has no normative references. Issued on 30 December 2022, it has applied since 1 July 2023.
