Language Systems, Inc.: description of the DBG system as used for MUC-4

LSI's Data Base Generation (DBG) system is a syntax-driven natural language processing system that integrates syntax and semantics to analyze message text. The goal of the DBG system is to perform full-scale lexical, syntactic, semantic, and discourse analyses of message text and produce a system-internal knowledge representation of the text that can serve as input to a downstream system or external data structure, such as the MUC-4 templates.
