Chapter 10Constructing Semantic and Product Networks

An interesting, novel, and relatively understudied class of complex networks is networks based on co-occurrence, or coincidence—the property of items being in the same place (or close enough) at the same time. The edges in co-occurrence networks are implicit: they are not given (and often not even obvious); you have to deduce, extract, and calculate them from other data, and this is a significant departure from the relatively intuitive way you build social networks. Co-occurrence networks are living proof that ...
