GRNTI 2022 master version. (Part 1. Developing thematic and structural organization of subject heading nodes)

The authors  introduce  the  findings  of their  research  on  updating  and improving  the  existing  master  version  of the  State  Rubricator  of Sci-tech  Information  (GRNTI) version 2021 and building  the  General Classification  Schedule  of the  master  GRNTI 2022 version. They define  the  main functions  of GRNTI as the standard classification  of the State System of Sci-tech Information. The functional efficiency  depends on the  compliance  of the  Rubricator’s subject  and  structural organization to the current  status  and trends  of scientific knowledge  and technologies.  The main  stages  of the  accomplished studies  are  described:  comparative intellectual analysis of subject  scope and hierarchy of GRNTI classes  and thematic description  of sections  within  the  Plan  of Fundamental and  Thematic  Scientific Research  for 2021–2030; submitting proposals  for GRNTI by researchers of relevant research  institutes and STI agencies;  analyzing and content editing  of GRNTI proposals, eliminating concept  duplication, and updating  links and references.  The authors  include  the  statistics of changes  distribution in  GRNTI  2021 by types: changed  subject  headings, new headings  introduction, and elimination of the  subject headings.  Statistical  indicators  are analyzed  to characterize GRNTI subject  and structural organization, as well as its thematic classes (2nd  and 3rd  level headings).
