Both Eigenfactor and SJR are based on the number of citations a journal receives from other journals, weighted by their importance, such that citations from important journals like Nature are given more weight than less important titles. Later in this post, I’ll describe exactly how a journal derives its importance from the network. In contrast, metrics like the Impact Factor or the do not weight citations: one citation is worth one citation, whatever the source. In this sense, the Eigenfactor and SJR get closer to measuring importance as a social phenomenon, where influential people hold more sway over the course of business, politics, entertainment and the arts.
