      I encounter "link analysis" when working with law enforcement and
      counterterrorism clients.

      Links analysis, from my outsider perspective, is linking together
      various objects for evidence mapping. These objects include people,
      cars, houses, businesses, phone numbers, other objects of ownership.
      It is felt that such analysis can uncover cells and gangs and other
      criminal conspiracies -- besides providing nice visuals for court.
      They do not use social network metrics but do a elementary form
      degree and cluster analysis, and have a good understanding of
      structural equivalence. The main tool in play for link analysis is
      i2's Analyst Workbook -- which has a strangle hold on that market.
