  <dc:description xmlns:ns0="xml" ns0:lang="en">The bipartite graph connecting products and reviewers of that product is studied  empirically in the case of amazon.com. We find that the network has power-law  degree distribution on the side of reviewers, while on the side of products the  distribution is better fitted by stretched exponential. The spectrum of normalised  adjacency matrix shows power-law tail in the density of states. Establishing the  community structures by finding localised eigenstates is not straightforward as the  localised and delocalised states are mixed throughout the whole support of the  spectrum.</dc:description>
