    <Paragraph position="0"> In this paper, a structural model of text coherence com~ putation has been proposed that strongly exploits the knowledge chunking inherent to fi~ame representations.</Paragraph>
    <Paragraph position="1"> These prccompiled knowledge structures are irtstantiatcd by the topical evolution of a text ax represented in the parser's bulletin. Tiros, various coherence phenomemt can be distinguished by particular instantiation pattents: f3 constant theme is defined by multiple instantiafions of aggregatiou (or conceptual association) relations for one particular f'r',une item in KB; ffl continuous thematization of rhemes is deiino ed by multiple instantiations of aggregation relations for continuously changing, though locally overlapping frame items in KB; \[-J derived theme is defined by multiple instantiations of generalization/classilication relations holding between subparts of a frame hierarchy in KB.</Paragraph>
    <Paragraph position="2"> A more elaborated formal description of this model - int:lnding those parts which could only be treated rather sketchily in this contribution - is given in llalm \[1991\]. The parser is currently running on SUN SPARCStations under Unix (SUNOS V4.1 A).</Paragraph>
    <Paragraph position="3"> The functionality described in this paper is fully operational and part of the TOPIC text understanding system.</Paragraph>
