    <Paragraph position="0"> We have provided algorithms for the interpretation/generation of a type of reply involving a highly context-dependent conversational implicature. Our algorithms make use of discourse expectations, discourse plans, and discourse relations.</Paragraph>
    <Paragraph position="1"> The algorithms calculate implicatures of discourse units of one or more sentences. Our approach has several advantages. First, by taking discourse relations into account, it can capture a variety of implicatures not handled before. Second, by treating implicatures of discourse units which may consist of more than one sentence, it avoids the limitations of a sentence-at-a-time approach. Third, by making use of properties of discourse which have been used in models of other discourse phenomena, our approach can be integrated with those models. Also, our model permits the same information to be used both in interpretation and in generation.</Paragraph>
    <Paragraph position="2"> Our current and anticipated research includes: refining and implementing our algorithms (including developing an inference mechanism for the discourse relation rules); extending our model to other types of implicatures; and investigating the integration of our model into general interpretation and generation frameworks.</Paragraph>
