   Project Description

Main Goal for LAW

To develop the Link Analysis Workbench (LAW), a Web-accessible tool where analysts and machines collaboratively perform link analysis by defining hierarchical and temporal patterns, that include uncertain and qualitative elements, and by defining domain dependent and independent search strategies for pattern application, through a graphical user interface that supports direct graphical browsing and editing of patterns, search strategies, and summaries and details of resulting matches.

Tangible Benefits of LAW

  • Analysts, aided by LAW, will be able to find patterns of links that constitute evidence for situations or actions of interest far faster than is possible without LAW and with far less effort
  • The reasoning behind this evidence and its role within analytic arguments will be recorded in a way that is transparent to anyone who probes the conclusions
  • LAW will allow analysts to easily define new patterns of interest and search control techniques for their application to support the specific needs of any analytic task
  • LAW will support and foster a collaborative environment where analysts jointly work with contemporaries and analysts from the past, learning from others, leveraging their thinking, and sharing the load
  • LAW will be transitioned into active use by intelligence analysts already using SRI’s structured argumentation tool, SEAS

   Software
Active Lisp Pages
ALP is a framework that allows the embedding of Lisp code inside HTML (or XML) pages, for use in server side web scripting.

FREEDIUS
FREEDIUS is a free Geospatial Image Understanding system. It is a portable, open-source successor to SRI’s 3DIUS system (including CME, Image-Calc, RADIUS Common Development Environment, and other Image Understanding tools).

LAW: Link Analysis Workbench
LAW is a system that helps intelligence professionals define and match patterns within large, incomplete, and noisy sets of relational data.
