ORA-LITE

ORA-LITE is a dynamic meta-network assessment and analysis tool developed by CASOS at Carnegie Mellon.  It contains hundreds of social network, dynamic network metrics, trail metrics, procedures for grouping nodes, identifying local patterns, comparing and contrasting networks, groups, and individuals from a dynamic meta-network perspective. ORA-LITE has been used to examine how networks change through space and time,  contains procedures for moving back and forth between trail data (e.g. who was where when) and network data (who is connected to whom,  who is connected to where …),  and has a variety of geo-spatial network metrics, and change detection techniques.  ORA-LITE can handle multi-mode, multi-plex, multi-level networks.  It can identify key players, groups and vulnerabilities, model network changes over time, and perform COA analysis.  Although all metrics available in ORA-LITE have been tested with large networks (10^6 nodes per 5 entity classes); ORA-LITE is itself limited to a maximum of 2,000 nodes per entity class. So you can have 2000 agents, 2000 organizations, and so on. The Professional version of ORA which is available from Netanomics (www.netanomics.com) has no limit on the number of nodes. Distance based, algorithmic, and statistical procedures for comparing and contrasting networks are part of this toolkit.

Based on network theory, social psychology, operations research, and management theory a series of measures of “criticality” have been developed at CMU.  Just as critical path algorithms can be used to locate those tasks that are critical from a project management perspective, the ORA-LITE algorithms can find those people, types of skills or knowledge and tasks that are critical from a performance and information security perspective.  Each of the measures we have developed are calculated by ORA-LITE on the basis of network data like that in the following table.

ORA-LITE can be applied both within a traditional organization or on covert networks.

Version of ORA-LITE (v3.0.9.179) offers the following improvements: released June 7, 2024
1) Improved BEND report
a. Added the Volume and Agreement tables based on the number of Negate and Back documents authored by a group
b. Added the Smiley Face analysis for the number of Excite, Dismay, and Neither documents authored by each group.
c. Spider plot has consistent green shading for “maneuvered-upon” (and red for “maneuvers”)
d. Added a table of the Most Sarcastic Actors based on the number of potentially sarcastic messages/posts sent by the actor
e. Added as an agent and document attribute to each message/post a potential sarcasm attribute
f. Added CSV output for the sarcasm scores of agents and documents
g. Added an additional layman’s explanation of the transition network.
h. Enlarged the hyperlink font-size for the drill downs in the tables

2) Stance detection report

a. Added the CUES table above to the Stance Detection report to show cues and group quality metrics.

3) Simplified the Table Data Import Wizard importer.

4) Data Import Wizard improvements:

a. The user can now drag-n-drop or copy-paste a general file and ORA currently auto-detects the format for Telegram, Table Delimited, TalkWalker, and Pajek. The Wizard is opened with the format automatically selected and when the user browsers to select files, these files are automatically available.
b. Crowdtangle importer

5) Telegram importer and report changes:

a. The average number of replies per post has been added as a channel and group measure.
b. Node markers have been added to all tables so that bots, news agencies, and verified now works like all other social media reports
c. A time series line chart showing the number of messages over time for the most popular channels and groups has been added.

6) JSON output for Node of Interest report.

7) Revised and updated the Missing Link report, which includes scalability, user-interface, and report layout improvements.

8) Semantic network report:

a. Added the ability to create, load, and save Concept Sets
b. Added the measures from the Power Point deck into the Semantic Network report
c. Improved the efficiency of the computation by eliminating duplicate processing, this and other changes support large data processing
d. Improved presentation of outputs.
e. Added a table of contents
f. Before calculating the cube analysis (e.g. is it a stereotype etc.) the networks are binarized.
g. New table showing concepts that most frequently co-occur within documents and another of which shows concepts that most frequently co-occur across documents

9) Parts of Speech and Communication Power report modifications:

a. Improved the efficiency of the computation by eliminating duplicate processing, this and other changes support large data processing
b. Improved presentation of outputs.

10) Improved visualization capabilities

a. More control over node and link sizing and coloring
b. Faster visualization
c. New visuals in some reports

11) Underlying libraries updated

12)  Miscellaneous bug fixes

Hardware Requirements

  • CPU with 500 megahertz or higher processor clock speed recommended (3 Ghz is recommended for large datasets)
    * Intel Pentium/Celeron family, or AMD K6/Athlon/Duron family, or compatible processor recommended
  • 512 MB of RAM or higher recommended (1 GB preferred)
  • 500 MB of available hard disk space

Notes on Multi-Core Processors

  • ORA-LITE can take advantage of all the cores in your machine.  All
    computationally intense measures are multi-threaded.

System Interaction

  • ORA-LITE has a java front end and a C++ backend. It does NOT touch the system registry.
