Summary: |
Network theory provides a powerful tool for the
representation and analysis of complex systems of interacting agents. Here
we investigate the United States House of Representatives network of
committees and subcommittees, with committees connected according to
``interlocks'' or common members. Analysis of this network reveals clearly
the strong links between different committees, as well as an intrinsic
hierarchical structure within the House as a whole. We show that network
theory, combined with analysis of roll call votes using singular value
decompositions, successfully uncovers political and organizational
correlations between committees in the House without the need to
incorporate outside political knowledge. This work is joint with Peter
Mucha, Mark Newman, and Casey Warmbrand. |
