Intercohesion

From InterSciWiki

Intercohesion is a term first used, perhaps, in “Improving the Clustering Capabilities of Consensus” 2006 Lecture Notes in Computer Science, Abstract: “This paper introduces SOM as a clustering method to evaluate complex and uncertain knowledge in Consensus, a distributed security system for vulnerability testing; it proposes new metrics to evaluate the cohesion of every cluster, and also the cohesion between clusters; it applies unsupervised algorithms and validity metrics to a security data set; and it presents a method to obtain the best number of clusters regarding these new cohesion metrics: Intracohesion and Intercohesion factors.”

It was not used earlier by Palla et al 2005, but was defined by Vedres and Stark (2007, 2008) for intersecting and mutually interpenetrating cohesive structures. It is the special cases of the concept and measure for Structural cohesion but can be measured more specifically, as in their work, by "Clique percolation" as defined in the work of Palla et al. (2005, 2007).
