MeSH 2023 - New Headings with Scope Notes

This dataset includes all newly added MeSH Main Headings for 2023. Headings play a central role in MeSH vocabulary as a unit of Indexing and retrieval. With the exception of Class 3 Descriptors, all descriptors are organized into a numbered tree structure or hierarchy that allows users to browse in a orderly fashion from broader to narrower topics. Scope Notes provide a concise summary describing the meaning and scope of the MeSH Descriptor.

本数据集收录了2023年新增的所有MeSH主要主题词。主题词在MeSH词汇体系中扮演核心角色，作为索引和检索的基本单元。除第三类描述符外，所有描述符均组织成编号的树状结构或等级体系，使用户能够有条不紊地从广义至狭义的主题进行浏览。范围注释提供了对MeSH描述符含义及适用范围的简要概述。
