Developing  technologies that support collaboration requires understanding how knowledge  and expertise are shared and distributed among community members. We explore  two forms of knowledge distribution structures, coordination and cooperation,  that are central to successful collaboration. We propose a novel method for  detecting the coordination of strategic communication among members of  political communities. Our method identifies a 'rapid semantic  convergence', a sudden burst in the use linguistic constructions by  multiple individuals within a short time, as a signature of coordination. We  apply our method to the public statements of U.S. Senators in the 112th U.S.  Congress and construct coordination and cooperation networks among these  individuals. We then compare aspects of these networks to other known  properties of the Senators. Results indicate that the detected networks  reflect underlying tendencies in the social relationships among Senators and  reveal interesting differences in how the different parties coordinate  communication.
