The Link Analysis Workbench is being developed at SRI International's Artificial Intelligence Center.
Intelligence analysts work with incomplete and noisy data. Their information needs are often hard to express, and almost impossible to get right the first time. Their information gathering is rarely a one-shot operation. Instead, the process is generally an evolutionary cycle, where the pattern of interest is constructed and then repeatedly refined based on results returned from the data. The analyst is heavily involved at all stages of the cycle. Supporting this cycle poses technical challenges for the tool developer, both in designing a pattern language flexible enough to describe both very specific and very general match criteria, and in producing a system that allows the analyst to define and refine patterns and interpret results quickly.
LAW features several characteristics that are important for this cycle:
