EmBiology (formerly EMBiology) is a web-based Software as a service tool from Elsevier in which researchers can view biological relationships between entities, such as genes, proteins, and cells.[1]
Launched in 2023, EmBiology queries a Biological Knowledge Graph with 1.4 million entities connected by 15.7 million relationships. It uses a Sankey diagram to visualize search findings, and displays "snippets" of text from relevant scientific literature.
EmBiology was originally launched as EMBiology in 2005 as a life science bibliographic database in a partnership with Ovid Technologies as a smaller version of Embase.[2]
