    <Paragraph position="0"> We tested bracketing accuracy on the Monroe corpus (Stent, 2001), which contains collaborative emergency-management dialogues. Aug-TRIPS is comparable to TRIPS in accuracy, but produces fewer constituents (Table 1). The Bikel parser has slightly higher precision/recall than either TRIPS or Aug-TRIPS, since it can choose any bracketing structure regardless of semantic coherence, while the TRIPS systems must find a legal pattern of feature unifications. Aug-TRIPS also has better precision/recall when parsing the longer sentences (Table 2).</Paragraph>
