What PubMed AI Discovery does
PubMed is a free search service from the National Library of Medicine for biomedical literature, drawing on MEDLINE, life science journals and online books, with links to full text through PubMed Central and publisher sites. It is used by researchers, clinicians, students and anyone looking up medical studies. Its default relevance sort uses a machine learning algorithm to re-rank results, and a citation sensor uses fuzzy matching to find papers despite errors in a query. Other features include Advanced Search, filters, Clinical Queries, the MeSH database, citation matchers, email alerts, the E-utilities API and an experimental Linked Discoveries tool. Searching costs nothing, though some publisher full text may require a fee.
