We are pleased to announce that a new Advanced metric has been added to Polinode - Core / Periphery. You will find it in the Explore View under Metrics then Advanced metrics. There is some basic documentation there within the application. Further documentation on this new metric can be found at docs.polinode.com: https://docs.polinode.com/guide/networks.html#metrics. Please see the Core Periphery metric in the linked to section of the documentation.
This metric is designed for you to be able to classify nodes in the network into those nodes that are in the “core” of the network and those that are in the “periphery”. There are in fact two different algorithms - the first assumes there is just one core / periphery structure in the network whereas the other allows for multiple core / periphery structures.
