Hi Lin,

Thanks for your reply. I just checked betweenness centrality for nodes. It's a good measure but it's not utilizing any clustering or community structure. I did do some googling and this paper defined a measure that could be useful. Just FYI

    Dear developers,

    This question just came up on top of my head. Is there any
    algorithms that assign a hub score to nodes in a community structure?
    For example, if identified with a community structure, certain
    nodes in the communities may be essential that contain more
    inter-community edges
    than the others. These nodes are also very important for overall
    connectivity. Identifying these hubs will also aid the
    understanding of the
    community structure.

    Are there any publications on this kind of 'hub score'?
