Abstract:
In previous work, we proposed a focus-based multi-level clustering
technique. It consists in computing a particular clustered graph from a
given graph and a focus. The resulting clustered graph is called multi-level
outline tree. It is a tree whose meta-nodes are sub-sets of nodes. A
meta-node is itself hierarchically clustered depending on its connectivity.
In this paper we introduce a cluster cohesiveness measure to enhance the
results of the previously proposed algorithm. We further propose an
optimization of this algorithm to support fluid interaction when focus
changes. Finally, we report the results of a case study that consists in
applying the enhanced algorithm to citation graphs where documents are
considered as vertices and citation links as edges.
