MeSH 2024 Update - Split Report lists terms replaced by a set of terms instead of a single term. The dataset includes changes from previous years, starting from 2023, and is hosted by datadiscovery.nlm.nih.gov. It was last updated on 2025-05-29 12:19:32.
Use Cases
- Track the evolution of medical terminology by analyzing TERM_TO_BE_SPLIT and Year to identify deprecated concepts.
- Map old terms to new concepts using REPLACEMENT_OPTION_UI and REPLACEMENT_OPTION for data migration in biomedical databases.
- Analyze the complexity of vocabulary changes by examining OPTION_COUNT and IS_NEW to understand splitting patterns.
- Validate the consistency of MeSH updates by cross-referencing SPLIT_UI with other MeSH reports using the 7 available columns.
Strengths
- Includes changes from previous years, starting from 2023, providing a multi-year view of vocabulary evolution.
