***** To join INSNA, visit http://www.insna.org ***** Mark: Are their applications of SNA that can be used to produce better search? Of course--that's what PageRank is (essentially an eigenvector centrality measure on a slightly modified version of the Web graph). :) (And yes, I think there are other applications of SNA to search, e.g., in personalization. But the basic idea of treating the pages and hyperlinks as a social network, and inferring rank on that basis, is unlikely to be eclipsed (as a means to better search) for at least a while yet, I suspect.)
