    <Paragraph position="0"> Our proposal for tile description of lexically biased discourse structure relations resembles l)anlos' work (Danlos, 1987), who presented acceptable ehmse pattern sequences explMtly in a Discourse Grammar.</Paragraph>
    <Paragraph position="1"> The. basic difference between Danlos' work and ours is that in the Discourse (h'amrnar, clause pattern seqtlences are represented as concreLe valency sehelllatlt while in our model they are represented as functional distinctions that encode sequcndes o\[' I,FS. As a result, we do I/el. \['aee the probhml of being restricted to a concrete small domahl as l)anlos does.</Paragraph>
    <Paragraph position="2"> Metoer's text phumer (Meteer, 1992) is another prol)osa.l for the realization of lexically biased discourse strucl.ure relations. \[/ut while we argue that lexically biased (liscourse structure relal;ions are to I)e realized by a functionally motiwd,ed h'.xical choice.</Paragraph>
    <Paragraph position="3"> model, Meteer sugggests a single struetundly moti rated model For text planning, which also sul)sumes lexical choice. This is different from, e.g., (R.ubineff, 1992), who ensures the expressil)ility o1&amp;quot; discourse structure relations provide(l I)y a conventional text l)hmner by annotating linguistic structures.</Paragraph>
    <Paragraph position="4"> Elhadad's prol)osal (Elhadad, 1992)to use 7bpoi (inference ,'ules that encode relations between t)ropo sitk)ns incorporating lexical material) as discourse structure relations is aimed at exploiting lexical phenomena for discourse organization. Elhadad focuses, however, on the 'argumentative potential' of lexieal items r;~t.her t.llan on lexica.lly biased discourse structure relations.</Paragraph>
