    <Paragraph position="0"> \Ve have described a domain independent summarization engine which allows for efficient summarization of large documents. The algorithm described is clearly O(n) in the number of nouns in the original document.</Paragraph>
    <Paragraph position="1"> In their research, Barzilay and Elhadad showed that lexieal chains could be an effective tool for automatic text summarization (Barzilay and EIhadad, 1997). By developing a linear time algorithm to compute these chains, we have produeed a front end to a summarization system which can be implemented efficiently. An operational sample of this demo is available on the web at http://www.eecis.udel.edu/- silber/research.htm.</Paragraph>
    <Paragraph position="2"> ..... While. ,usable currenlfly, the-system provides a platform for generation research on automatic text summarization by providing an intermediate representation which has been shown to capture important concepts from the source text (Barzilay and Elhadad, 1997). The algorithm's speed and effectiveness allows research into summarization of larger documents. Moreover, its domain independence allows for research into the inherent differences between domains.</Paragraph>
