INTRODUCTION
</SectionTitle>
    <Paragraph position="0"> The data extraction system submitted by Paramax for evaluation in MUC-4 is a new implementatio n written in CLIPS, a forward-chaining system developed and maintained by NAS A's Johnson Space Center [1]. Using CLIPS as a forward-chaining engine is desirable because it runs on a wide range of machine s (including Sun Sparc stations, Apple Mac IIs, and PCs), it is available at little or no cost from th e government, it is fast, and it comes with good documentation and support services.</Paragraph>
    <Paragraph position="1"> The Paramax MUC-4 development team consisted of one Paramax staff member and one governmen t employee on sabbatical at Paramax . The data extraction module was designed and implemented in les s than two months, using less than four person-months of labor . Developing inference rules for the system did not require any linguistic expertise or any detailed knowledge of CLIPS--neither of the developer s had any prior experience using CLIPS . All that was required was knowledge of the domain and the dat a extraction task to be performed .</Paragraph>
