Menczer Praises "Motifs" Study

There are many types of networks in the world -- computer webs like the Internet, connections among components in electronics, relationships among friends and acquaintances, transportation grids, food relationships among animals, connections among neurons, and interactions among genes. Scientists from the Weizmann Institute of Science in Israel and Spring Harbor Laboratory have shown that it is possible to categorize networks by looking at certain recurring circuits, or motifs, within the networks. The researchers work is interesting because "it tries to make connections between the different types of complex networks beyond the power-law results that we have seen thus far," said FILIPPO MENCZER, an assistant professor of management services at the University of Iowa. "It goes beyond global link analysis such as the studies which unveiled the scale-free/power degree distribution of many complex networks including the Web, and starts focusing on more local structures," he said.
