    <Paragraph position="0"> The PROTEUS system which we have used for MUC-3 has three main components : a syntactic analyzer, a semantic analyzer, and a template generator .</Paragraph>
    <Paragraph position="1"> The PROTEUS Syntactic Analyzer was developed starting in the fall of 1984 as a common base for all th e applications of the PROTEUS Project. Many aspects of its design reflect its heritage in the Linguistic Strin g Parser, previously developed and still in use at New York University . The current system, including the Restriction Language compiler, the lexical analyzer, and the parser proper, comprise approximately 4500 lines of Common Lisp.</Paragraph>
    <Paragraph position="2"> The Semantic Analyzer was initially developed in 1987 for the MUCK-I (RAINFORMs) application , extended for the MUCK-II (OPREPs) application, and further revised for the current evaluation . It currently consists of about 3000 lines of Common Lisp (excluding the domain-specific information) .</Paragraph>
    <Paragraph position="3"> The Template Generator was written from scratch for the MUC-3 task; it is about 1200 lines of Commo n Lisp..</Paragraph>
