Applying Relation Algebra and RelView to Measures in a Social Network
Harrie de Swart
We present an application of relation algebra to measure players strength in a social network with influence between players. In particular, we deal with power, success, and influence of a player as measured by the Hoede-Bakker index, its generalization and modifications, and by the influence indices. We also apply relation algebra to determine followers of a coalition and the kernel of an influence function. This leads to specifications, which can be executed with the help of the BDDbased tool RelView after a simple translation into the toolÃs programming language. As an example we consider the present Dutch parliament.
