    <Paragraph position="0"> A semantic head driven generation method based on feature structures is proposed in this paper. This method efliciently generates all possi ble phrase structures fl'om a given semantic feature structure. The method involves multiple indexing of feature structures and a precombination nlechanisn\]. These lnechanisnls constrain applicable gralnmatical knowledge beR)re instantiation; thus the method eliminates the copying of fegture structures, which consunles conlputillg resources.</Paragraph>
    <Paragraph position="1"> The proposed grammar notation is appropriate for describing idiomatic phrase structures easily. To make the best use of the notation, we are extending the Mgorithm so that it can AcrEs De COLING-92, NAmes, 23-28 AO13&amp;quot;r 1992 3 8</Paragraph>
