  Link Analysis
  6-74. Link analysis is used to show contacts, associations, and relationships between persons, events,
  activities, organizations. The two most effective types of link analysis tools are the activities
  and association matrixes and the link diagram.
  Activities and Association Matrixes
  6-75. Using the activities and association matrixes, the analyst can pinpoint the optimal targets
  for further intelligence collection, identify key personalities within an organization, and considerably
  increase the analyst's understanding of an organization and its structure. The activities matrix is used
  to determine connectivity between individuals and any organization, event, address, activity, or any other
  nonpersonal entity. The association matrix is used to determine existence of relationships between
  individuals. Figure 6-11 shows an example activities matrix, and Figure 6-12 shows an example
  association matrix.
