PubMed classification 202505

The classification contains about 21 million PubMed publications from 1995 onward. It has been created using clustering in a citation network.The January 2024 update is a complete new version of the classification based on new clustering and labeling.File descriptionPMID_cluster_relation_[date].csv contains the relation between PMIDs and clusters. Four levels are included:Level 1 - Topics - Most granularLevel 2 - SpecialtiesLevel 3 - DisciplinesLevel 4 - Discipline group - Most coarseLabelsFor each level there is a table with labels (e.g. labels_lev1_[date].csv), related by an id (e.g lev1_cluster_id).StatsFor each level there is a table with statistics (e.g. lev1_stats). The table includes the columns below. For more information about the "Clinical", "Human", "Animal" and "Molecular/Cellular Biology" categories, see https://nih.figshare.com/collections/iCite_Database_Snapshots_NIH_Open_Citation_Collection_/4586573p - The number of publications in the cluster in the initial clustering.pct_clinical - The proportion of clinical articlessum_clinical - The number of clinical articlespct_human - The average of the fraction of MeSH terms that are in the "Human" categorysum_human - The sum of fraction of MeSH terms that are in the "Human" categorypct_animal - The average of the fraction of MeSH terms that are in the "Animal" categorysum_animal - The sum of fraction of MeSH terms that are in the "Animal" categorypct_molecular_cellular - The average of the fraction of MeSH terms that are in the "Molecular/Cellular Biology" categorysum_molecular_cellular - The sum of fraction of MeSH terms that are in the "Molecular/Cellular Biology" categoryVisualizations:Base map of PubMed 2015-2024Map of PubMed 2023 - Including hyperlinks to publicationsMap colored by % ClinicalMap colored by % HumanMap colored by % AnimalMap colored by % Molecular/CellularSee the figshare collection for further description.
