Noun network structure. (a) Correlation matrix for all words in the core vocabulary. The ordering of indices is the same as results from clustering (see Fig. 4b). Yellow and blue shades indicate high (positive) and low (negative) values. (b) Fraction of nodes in the largest network component as a function of the correlation threshold θ used to build the network. At the transition, around the critical value θ*=0.65, the network breaks down into a large number of small components. (c) Network degree distribution at the critical value of the threshold. The approximated power-law profile, with slope s≈−2, is a signature to a scale-free network. (d) Diagram of the largest network component at the critical threshold.
