In our last post, we provided an introduction to graph thinking and the concept of nodes (or vertices) and edges (or links) as a way to describe networks. As examples, we pointed to Facebook (a social graph with connections between people and the things that people like) and Google (which uses the connections between web pages as a measure of relevance).
Graph thinking, derived from a branch of mathematics called Graph Theory, is all the rage in Silicon Valley. For instance, in August, Gartner identified knowledge graphs and graph analytics as two of 29 emerging technologies CIOs should experiment with in the next year.
