  In order to generate cohesive discourse, many of the relations holding
between text segments need to be signalled to the reader by means of cue words,
or {\em discourse markers}. Programs usually do this in a simplistic way, e.g.,
by using one marker per relation. In reality, however, language offers a very
wide range of markers from which informed choices should be made. In order to
account for the variety and to identify the parameters governing the choices,
detailled linguistic analyses are necessary. We worked with one area of
discourse relations, the Concession family, identified its underlying
pragmatics and semantics, and undertook extensive corpus studies to examine the
range of markers used in both English and German. On the basis of an initial
classification of these markers, we propose a generation model for producing
bilingual text that can incorporate marker choice into its overall decision
framework.
