PubMed classification v3 202202

For each level there is a table with labels (e.g. labels_lev1_[date].csv), related by an id (e.g lev1_cluster_id). The February 2022 update is a complete new version of the classification based on new clustering and labeling. <br> A visualization of the clusters is available in GitHub. <br> PMID_cluster_relation_[date].csv contains the relation between PMIDs and clusters. Four levels are included: Level 1 - Topics - Most granular Level 2 - Specialties Level 3 - Disciplines Level 4 - Discipline group - Most coarse <br> Added_pubs_version_[nih occ version].csv contains the same information as above, but for publications that have been assigned to clusters after the initial clustering proceedure. <br> See the figshare collection for further description.
