Pattern matching for intelligence organizations is a challenging
problem. The data sets are large and noisy, and there is a flexible
and constantly changing notion of what constitutes a match. We are
developing the Link Analysis Workbench (LAW) to assist an expert user
in the intelligence community in creating and maintaining patterns,
matching those patterns against a large collection of relational data,
and manipulating partial results. This paper describes two key facets
of the LAW system: (1) a pattern-matching module based on a graph
edit distance metric, and (2) a system architecture that supports the
integration and tasking of multiple pattern matching modules based on
their capabilities and the specific problem at hand.

The Link Analysis Workbench
The goal of this project is 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 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.
