During the presentation I will talk about the problem of creating group centrality measures based on node centrality measures. I will show previously known and obvious extension methods and discuss their pros and cons. I will present a new method, which has a lot of variations. I will explain the intuitions behind the method and its variations. I will talk about the expressiveness of the method - which group centrality measures can be created with it. I will show how previously known method relate to the new method and its variations. I will go over how to use the method to extend a few selected centrality measure classes.
