GB/T 42406-2023Industrial cloud service - Knowledge base access and manage requirement (English PDF)

Foreword

This document was issued on 17 March 2023 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 October 2023.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 42406-2023 covers how a knowledge base is connected to an industrial cloud service and how it is managed once it is connected. Access comes first: an overview of why knowledge bases are brought onto a cloud platform at all, so that knowledge and experience are aggregated and shared instead of staying inside one plant, then the access process itself and the requirements a base has to satisfy to be admitted. Management follows as four activities — retrieval, which starts with establishing a directory for the base, invocation, maintenance, and statistics — each with its own requirements. A terms clause defines what the document means by knowledge, and an abbreviations clause covers the API through which the platform is reached. Industrial know-how tends to accumulate as documents and habits held by individual sites and individual people; moving it behind a shared platform only pays off if what may be admitted, how it is found and how it is kept current are settled beforehand rather than left to each connection. Of use to industrial cloud platform operators, manufacturing IT departments, and integrators building knowledge services.

This document specifies the requirement and management specification for knowledge

base access to industrial cloud services.

This document is applicable to knowledge base retrieval, invocation, maintenance and

statistics that meet the requirements of industrial cloud services.

5 Knowledge base access requirements

5.1 Overview

In the process of industrial cloud service, through the access to knowledge base,

knowledge aggregation and sharing is realized; to provide knowledge, experience and

cases for industrial cloud service customers AND realize the reuse and sharing of

knowledge.

The knowledge base includes public mold library, parts library, fault diagnosis rule

library, algorithm model library, etc.

Knowledge bases generally use models, such as rules, semantic nets, knowledge trees,

and knowledge graphs, to represent knowledge.

5.2 Access process

The knowledge base access process standardizes the main steps when accessing the

knowledge base. It is divided into four parts: "planning-execution-testing-optimization":

a) Knowledge base access planning shall include the process of defining knowledge

base access content and access solutions;

b) Knowledge base access execution shall include the process of accessing the

industrial cloud knowledge base AND form industrial cloud service capabilities;

dynamic recycling mechanism for resources after the knowledge base is removed.

d) It shall comply with the requirements of 7.3.5.2 in GB/T 37700-2019.

5.3.3 Access testing

Access testing shall:

a) Verify the integrity, compatibility, consistency, and security of the accessed

knowledge base;

b) Check whether the communication bandwidth and capacity requirements for

accessing the knowledge base can be met.

6 Management activities and requirements

6.1 Overview

Knowledge base management activities include knowledge base retrieval, invocation,

maintenance and statistics. Retrieval includes establishing knowledge base directory,

searching ranking, etc. Invocation includes specific industrial scenario applications,

knowledge base content improvement, etc. Maintenance includes knowledge base

backup management, disaster recovery management, internal personnel management,

classification management, and knowledge base operation monitoring, etc. Statistics

include classification statistics, ranking statistics, statistical analysis, etc.

6.2 Retrieval

During the industrial cloud service process:

a) It shall establish knowledge base directory and index;

b) It shall provide different types of retrieval interfaces, such as API, Web services,

command line, etc.;

c) It shall be able to provide corresponding retrieval services according to different

authority levels;

d) It shall provide the function of pushing search hot words;

e) It can provide synonym search function;

f) It can integrate contextual retrieval technology, query questions and user

information;

g) Through plug-ins and other methods, it shall convert knowledge base proprietary

format files (drawings, models, etc.) into visual results.

6.3 Invocation

During the industrial cloud service process:

a) It shall provide interfaces or tools for calling the knowledge base to corresponding

industrial scenarios and business departments;

b) During the actual invocation process, it shall put forward the requirements for

new knowledge and improve the content of the knowledge base;

c) The knowledge base invocation process shall include:

1) Clarify the invocation template, invocation plan and invocation objects;

2) Carry out the invocation process; combine industrial application scenarios;

solve practical problems according to the corresponding knowledge base;

3) Conduct performance evaluation on invocation results; evaluate new

knowledge needs and acquisition methods.

6.4 Maintenance

During the industrial cloud service process, it shall:

a) Provide knowledge base user management, including account management,

permission management, etc.;

b) Provide knowledge base review management;

c) Provide knowledge base backup and archive management;

d) Provide knowledge base classification management;

e) Provide knowledge base operation monitoring function; and run records can be

viewed through logs;

f) Provide knowledge base update function, to ensure compatibility between the

updated version and the original version;

g) Provide knowledge base disaster recovery management;

h) Have a knowledge base intellectual property protection mechanism;

i) Provide security protection mechanisms, including content privacy and leakage

prevention mechanisms.
