Previous attempts to describe the "structure" of social systems have failed either because of the researcher's presuppositions about the system or because of his inability to deal with the massive amounts of data that a human system necessarily generates. Recent advances in computer software, Network Analysis Program (NEGOPY). have made it possible to gather data about the communications between people and to have the computer translate the results into a topological interpretation of their relationship. Once the computer has identified individuals as either isolates, group members, or liaisons agents, decriptive statistical techniques can be used to further explain the variety and intensity of relationships.
