This paper provides a quick summary of our technical approach, which has been developing since 1991 and wa s first fielded in MUC-3. First a quick review of what is new is provided, then a walkthrough of system components. Perhaps most interesting is out analysis, following the walkthrough, of what we learned through MUC-6 and o f what directions we would take now to break the performance barriers of cur rent information extraction technology. TECHNICAL APPROACH Our approach is a synthesis of statistical and linguistic models of language, embodied for MUC-6 in the PLU M system (Probabilistic Language Understanding Model) .
