This project uses data from the Occupy Wall Street Project List (Issue 2, April-May 2012) to map connections between the Occupy movement and other organizations. The data for this small study comes from the project descriptions, which often include lists of partners.
Using the open-source network analysis tool Gephi, we can examine these connections in various displays. These graphs provide an abstract spatial sense of how groups are related, as well as the activity and flow across this structure. By coding partners by type, we can also see how certain types of groups (e.g., NYCGA working groups) are connected with other types (e.g., unions, religious/spiritual organizations, political parties).
Figure 1. Project partners in a force-directed network graph. Each group is represented as a node connected to other groups (nodes) through a project (line/edge). Some nodes are bridge nodes, connecting different parts of the network. In some of the tighter clusters, organizations (nodes) are close to each other because they partner with each other on the same projects. Some nodes (esp. yellow NYCGA nodes) are prominent in the sense that they have connections to many other nodes.
Figure 2. Project partners in a force-directed network graph (curved lines). Each group is represented as a node connected to other groups (nodes) through a project (line/edge). Groups cluster together when they partner on the same project (e.g. groups working primarily on “Health Care for the 99%” are largely clustered at the right of this graph; yoga, wellness, and spiritual groups are clustered at the bottom right). As groups partner with multiple projects, they are pulled away from the cluster surrounding any one project, and pushed toward the center of the graph (e.g., the OWS Arts & Culture working group near the center of this graph has partnered with many different projects).
Figure 3. Project partners in a radial graph with edges colored by target node type. This graph shows that most connections terminate in a wide variety of groups, including larger Occupy movement (red), political (green), religious/spiritual (blue) and union (purple) groups—and especially the latter three given how few of these groups are included in the overall dataset. Since the partnerships contained in the project list are neutral with respect to order (A with B = B with A), this graph does not show the direction of activity per se, merely the prominence of the various types of organizations that are connected by common projects.
The general method developed here may be extended in several ways:
