A public version of *ORA from the CASOS Center at Carnegie Mellon
University is available at

*ORA is a risk assessment tool for locating individuals or groups that
are potential risks given social, knowledge and task network
information.  Essentially, first you use information about people to
“connect the dots.”  Then, *ORA examines this network and finds those
dots, those people, who represent a threat to the overall system.
Individuals are risks, e,g,, if their removal from the network would
debilitate it (the critical employee)  or if they were to feed false
information to others they could create havoc (the rumor monger).

New Features in the latest v1. release include:

Improved scalability:
- An improved large-scale layout visualization algorithm that is an
order of magnitude faster.  The layout of 10,000 nodes went from 120
seconds to 10 seconds.
- The "View Measures Over Time" includes the Dynamic MetaNetwork, and
can handle many thousands of time periods.

Improved coordination between *ORA components, such as modifying nodes
or links in the Network editor, Network Visualizer, or Geospatial

*ORA now includes a Word Cloud generator, able to size words by
freqency, measure, or attribute.

Improved support for foreign languages by allowing users to work data
or visualize it by changing the appropriate font.

The Network Visualizer can be launched in a "blank slate" mode,
allowing the user to create data from inside the visualizer, and
adding and adjusting nodes and links.

The Geospatial reporting has been improved by adding a measures such
as spatial closeness centrality and spatial degree centrality.
