Language Systems, Inc.: MUC-3 test results and analysis

Table 1 summarizes LSI's scores for Phase II of MUC-3. In evaluating these scores, which place LSI about two/thirds of the way down in a results-ranked list of MUC-3 participants, it should be noted that our MUC-3 system reflects a major redevelopment of the key components of the DBG message understanding system, which is currently in process. Specifically, innovative development of a parser based on government-binding principles is under way, with associated revisions of the lexicon, functional parse (recovery of the predicate/argument functions representing the underlying semantic structure of the sentence), and DBG template generation and frame hierarchy components (the areas indicated by the heavy lines in the system flow chart shown in Figure 1).
