How to compute the K-CORE or K-SHELL？

[gillxiao]

anybody can tell me How to compute the K-CORE or K-SHELL？

i know that the filter support K-CORE, but i want to know each node's value.

Thats a good question. The filter won't store the k values for nodes. You can create a plugin for doing that.

Also, what is K-shell? I don't know this metric.

I recommend you read: http://arxiv.org/pdf/cond-mat/0509102v3.pdf and http://arxiv.org/abs/cs/0504107
for information on what k-cores are and how you can visualize them.

I found the best way to have anything to do with k-cores was to use igraph to compute them, add them in a "metric" column in the data laboratory in Gephi and visualize it there.
