MUC-5 EXPERIENCE AND SUMMARY
</SectionTitle>
    <Paragraph position="0"> The innovative aspect most responsible for our success this year was exploitation of the concept hierarchy , especially the links from lexical items to concept nodes in the hierarchy, which facilitated generation of the internal LSI templates . Recall scores steadily improved during addition of slot-filling rules without significantly increasing overgeneration and compromising precision . The preliminary addition of event semantics did not degrade system performance, but the complete system is not yet able to take full advantage of it.</Paragraph>
    <Paragraph position="1"> Improvements in this aspect of the DBG system should push scores significantly higher.</Paragraph>
