    <Paragraph position="0"> In the present paper, we have approached text planning for the generation of explanatory NL answers in logic based question-answering systems. Assuming a two step generation paradigm, we soundness and portability provided by a logic based knowledge representation technique, supports the generation of better NL explanations of the question-answering system's reasoning. In terms of the planning activity, the rhetorical relations and the rhetorical schemata derived from proofs provide elements for the explicit marking of the final text's coherence.</Paragraph>

OF COLING-92, NAI, rrEs, AU6.23deg28, 1992 Moreover, with a rich representation of proofs, algorithms can be designed to manipulate the existing hierarchical structure, so that cohesion can be guaranteed by binding the pieces of information with discourse markers like &amp;quot;this&amp;quot;, &amp;quot;also&amp;quot;, &amp;quot;so&amp;quot;, and others, which all refer to information previously mentioned in the text and avoid possible misunderstandings due to the repetition of mentioned elements being interpreted as the introduction of new information.</Paragraph>
    <Paragraph position="2"> At the present moment, we are investigating general grammatical structures to realize the text plan and are not devoting much effort to customization of output to users needs, However, hierarchical structures and belief/intention oriented specifications of RST relations should allow for further stylistic elaboration of text. In this way, users should be provided with an exposition of reasoning more adapted to their personal knowledge. A specification of a text planner following suggestions presented in \[6\] is in progress.</Paragraph>
    <Paragraph position="3"> Future work in the short term should investigate aspects of the specification of the realization component.</Paragraph>
