Software
Net: Download version 1.25 here
a program written in C and perl for the creation and statistical
analysis of large networks (graphs). Linux version.
ATOM: Download it here
a program written in C for the calculation of the electronic properties
of isolated atoms. It relies on Relativistic Density Functional Theory.
Linux version only.

- Creation of tag co-occurrence weighted networks from lists of Tag Assignments.
- Reshuffle of a folksonomy as a null model.
- Creation of a folksonomy by a random walker exploring the semantic network.
- Creation of complex networks using the fitness model of "Caldarelli G. et al., PRL 89, 258702 (2002)".
- Creation of complex networks using the Barabasi-Albert model of preferential attachment.
- Graph reduction with the minimum betweenness criterium.
- Calculation of eigenvalues and eigenvectors of graph associated matrices (requires Lapack and GSL)
- Analysis of most relevant statistical quantities:
- degree distribution
- clustering coefficient
- degree correlation
