Can get a signed network and overlapping clusters?

Can get a signed overlapping network,which have both positive and negative links?

Hi @Lebesgue-zyker , signed networks are not supported by this application. A network itself can't be overlapping, which is not a property of a network. A network is a collection of linked nodes, where nodes and links can be weighed, and links can be directed. Only the resulting clusters (communities) can be overlapping.
This application supports weighted undirected networks and evaluates overlapping clusters.

However, if you have a signed network, then it is possible to transform a signed network into a non-signed representation. Look for the respective research papers, which are out of the scope of this thread. Conceptually, a network is a mathematical model of some physical system, where you can have distinct, i.e., signed and unsigned equivalent models of the same system.
Otherwise, you are welcome to extend this open-source application to support signed networks. Look for the respective research papers and extend the existing source codes!
