    <Paragraph position="0"> Thus far, we have developed hierarchies for the family of contrastive relations in English and French and the family of causal relations in English. Ultimately, we intend to establish a complete hierarchy of all the markers of discourse relations; this will not only allow us to choose between different markers, regardless of whether one or more are used, but will also help to determine their order when multiple markers are necessary. In the final version of the hierarchy, we intend to provide the generation system with statistical information on the likelihood of one marker following another. Such information will take account of the fact that certain markers tend to occur together more often than others. These statistics are currently being derived from tests on the International Corpus of English (Nelson, 1995).</Paragraph>
