From visone user support
The transformation tab allows to modify the network structure according to some specified rule such as computing a co-authoring network from an author-article network, or replacing reciprocated directed links by undirected links.
visone distinguishes between three different transformation levels
- link level, e.g., to merge parallel links or reverse link directions;
- node level to turn the network of individual nodes into a network among groups;
- network level, e.g., to collapse a two-mode network into one-mode networks, or Simmelian backbone extraction.
