• Gini index:

> index = GiniIndex('../astro/direct.edgelist.giant.degree', '../astro/coupling.edgelist.giant.degree', '../astro/cocitation.edgelist.giant.degree')

• Statistics about uncovered communities: min, max, avg, median, and standard variance

• Distribution of the cluster size

> load cluster_size
> cluster_size_distribution(direct_2396(:, 2), 100, 100)
> cluster_size_distribution(coupling_992(:, 2), 100, 100)
> cluster_size_distribution(cocitation_634(:, 2), 100, 100)

> cluster_size_distribution(coupling_113(:, 2), 50, 200)
> cluster_size_distribution(cocitation_113(:, 2), 50, 200)

• Distribution of the number of memberships of nodes

> python membership.py ../astro/n101831-k113-mmsb-linksampling/communities.txt
> python membership.py ../astro/n101053-k113-mmsb-linksampling/communities.txt

> DistOfMemberships('../astro/n82895-k113-mmsb-linksampling/communities.dist')

• Overlaps between thematic structures at a high level

> java -jar AstroConverter.jar Overlap -threshold 150 -input ../astro/n101831-k113-mmsb-linksampling/communities.txt -output ../astro/direct
> java -jar AstroConverter.jar Overlap -threshold 200 -input ../astro/n101053-k113-mmsb-linksampling/communities.txt -output ../astro/coupling

• Extract subgraph for visulization

load the file “subgraph.gml” in Gephi to visualize it. Use each node's “group” member and then edge's “color” member for “partitioning”. Use the bridgeness to size each node. (First, copy bridgeness to a new column with column type BigDecimal.)

> java -jar AstroConverter.jar Network -node 556 -top 4 -input ../astro/n101831-k113-mmsb-linksampling/gml/network.gml -output ../astro/n101831-k113-mmsb-linksampling/gml/subnetwork.gml
> java -jar AstroConverter.jar Network -node 2881 -top 3 -input ../astro/n101053-k113-mmsb-linksampling/gml/network.gml -output ../astro/n101053-k113-mmsb-linksampling/gml/subnetwork.gml
> java -jar AstroConverter.jar Network -node 354 -top 3 -input ../astro/n82895-k113-mmsb-linksampling/gml/network.gml -output ../astro/n82895-k113-mmsb-linksampling/gml/subnetwork.gml

Note that the option node is set to the first element in the first line of *.edgelist.giant.degree.

• Convert the solution to csv format
