PAPER
You can download the main
text of the paper and the Supplemental Material file
directly from the Physical Review E website.

to request a pdf copy.
CODE AND DATA
The distribution file IOPC.zip contains the Matlab
codes and datafiles used to produce the results of the
paper. Please refer to the paper (main text and
Supplemental Material file) for all details about the
algorithm and data.
The code and data can readily be adapted and used for your
own application (we hope so, at least). Please report any
bug or misfunctioning. If your research benefits of these
methods and algorithms, please let us know (and cite the
paper...).
The zip file contains:
- InOutPseudoCommunities.m
: main code for (pseudo)community detection. The user
specifies the network, the type of structures to seek
for (e.g., out-communities, or in-pseudocommunities),
and a few computational parameters. Also, she/he
interactively set the quality threshold and the level
of pruning: the resulting (pseudo)communities are
stored in the workspace, and their fetaures are
graphically summarized.
- phi.m:
function used by the main code.
- maximalCliques.m:
function used by the main code.
The following datafiles are included (see the paper's Supplemental
Material for details):
- A_wtn.mat
: world trade network.
- A_wtn61.mat
, A_wtn75.mat : world trade
network for "leather, leather manufactures, and
dressed furskins" (61) and "office machines and
automatic data-processing machines" (75).
- A_ownership.mat
: ownership relations among Italian companies.
- A_airports.mat
: worldwide airports and their flight connections.
- A_leadership.mat
, A_prison.mat : networks of positive
sentiment in social groups.
- A_littlerock.mat
, A_stmarks.mat , A_stmartin.mat
, A_ythan.mat : networks
representing the food web in specific ecosystems.
- A_neural.mat
: neural network of the nematode worm Caenorhabditis
elegans.
- A_ecoli.mat
, A_scerevisiae.mat : transcriptional
regulation networks of the bacterium Escherichia
coli and of the yeast Saccharomyces
cerevisiae.
- A_politicalblogs.mat
: network of hyperlinks between weblogs on U.S.
politics.
- A_japanese.mat
: word-adjacency network obtained from
Shikibu's "The Tale of Genji".
- A_netscience.mat
: collaborations among researchers in network science.
- A_ppi.mat
: protein-protein interaction of the yeast Saccharomyces
cerevisiae.
SOFTWARE
REQUIREMENTS
The .m
code works correctly with Matlab 7.11.0 operating under
64-bit Windows 7 (but it probably work on previous
versions as well).
maximalCliques.m
is redistributed from Matlab Central (see copyright
notes).
