    <Paragraph position="0"> This paper has addressed the problem of determining the precise lexical and grammatical forms for expressing procedural relations between actions in the context of instructional text generation. The corpus-based methodology employed is well suited for this problem, providing both a principled means for cataloging the lexical and grammatical forms that are consistently used in instructional text and an environment for testing and confirming hypotheses concerning the contextual issues that co-vary with these forms.</Paragraph>
    <Paragraph position="1"> The issues of procedural planning, user modeling, and content selection, although of unquestionable importance to the broad goal of generating instructions, were not specifically addressed here. The current study makes a number of prescriptions for the type of information that such techniques would need to provide to the text planner pursuant to the generation of instructional text, but says nothing about how they should be implemented in order to achieve this.</Paragraph>
    <Paragraph position="2"> There are two fundamental contributions of the current study to the field of computational linguistics. The first is the analysis of instructional text itself. The current study has provided a characterization of certain aspects of instructional text that has been effectively applied to the generation of instructional text in general. This characterization is directly applicable to current work on instructional text, particularly in the context of natural language generation. The results can also serve as a source of preliminary hypotheses with respect to the analysis of other related genres.</Paragraph>
    <Paragraph position="3">  Keith Vander Linden and James H. Martin Expressing Rhetorical Relations The second is the detailed presentation of a methodology for managing diversity of expression at the textual level in the context of text generation. The approach involves collecting a suitable corpus of text, analyzing that text, implementing the results of the analysis in a text generator, and verifying the output of the generator. This approach is applicable not just to the problem of expressing procedural relations in instructional text, but rather to any lexical or grammatical aspect of any linguistic genre.</Paragraph>
