The social networks analysis method applied to information flow and transfer studies is discussed through the findings of a research project carried out upon organized social movements at Leopoldina suburbs (Rio de Janeiro). To study circumscribed groups information flows and communication structures, the ways informations circulate and are applied as resources of the struggle for better living condition were observed. Some measurements of the social networks analysis method matched with qualitative method instruments were applied. The results showed that some role players are responsible for networks dynamization, holding strategic positions, that also ensure them, the recognition by other agents. It can be noted that in the middle of these networks, through the constant tension between differences comprised, "knowledge networks" are formed, which in turn feed and redefine actions.
