PI-3Kinase Citation Network

This dataset consists of a directed network in edge list format where nodes correspond to articles in the scientific literature and edges represent citations. The network was constructed by seed set expansion (two rounds of citing and cited papers ) of the article (seed node) reporting the discovery of PI 3-Kinase activity. " Malcolm Whitman, C Peter Downes, Marilyn Keeler, Tracy Keller, and Lewis Cantley. (1988) Type I phosphatidylinositol kinase makes a novel inositol phospholipid, phosphatidylinositol-3-phosphate. Nature, 332(6165):644–646." The edge list comprises 17,970,340 nodes and 127,255,020 edges. The dataset was obtained from the Dimensions database via a two-level expansion of the seed node (article). The first expansion included four groups of nodes: the seed node; all publications cited by the seed node; all publications citing the seed node; and all publications cited by publications citing the seed node. The second expansion included all nodes that either cited or were cited by a node in the first expansion set. Node ids used were converted from the proprietary identifiers in Dimensions using a zero-based sequence of integer_ids [0: (n-1)]. Access to the original identifiers requires a license from Digital Science.
