    <Paragraph position="0"> The ITG constraints were introduced in (Wu, 1995).</Paragraph>
    <Paragraph position="1"> The applications were, for instance, the segmentation of Chinese character sequences into Chinese &amp;quot;words&amp;quot; and the bracketing of the source sentence into sub-sentential chunks. In (Wu, 1996) the base-line ITG constraints were used for statistical machine translation. The resulting algorithm is similar to the one presented in Sect. 3.1, but here, we use monotone translation hypotheses of the full IBM Model 4 as initialization, whereas in (Wu, 1996) a single-word based lexicon model is used. In (Vilar, 1998) a model similar to Wu's method was considered. null</Paragraph>
