    <Paragraph position="0"> John Lafferty and Andrew McCallum worked with the second author on developing CRFs. McCallum helped by the second author implemented the rst conjugate-gradient trainer for CRFs, which convinced us that training of large CRFs on large datasets would be practical.</Paragraph>
    <Paragraph position="1"> Michael Collins helped us reproduce his generalized percepton results and compare his method with ours. Erik Tjong Kim Sang, who has created the best online resources on shallow parsing, helped us with details of the CoNLL-2000 shared task. Taku Kudo provided the output of his SVM chunker for the signi cance test.</Paragraph>
