    <Paragraph position="0"> Witidn tile framework of Discourse Representation Theory (DRT) (Kamp(1981)) a Discourse Representation Structure (D1LS) is a pair &lt; U,K &gt; consisting of a set U of discourse referents (DRFs) and a met K of conditions. DRSs are interpreted modeltheoretically. DRT uses a variant of tim Davidsonian method of talking about events: timy are treated as a kind of objects.</Paragraph>
    <Paragraph position="1"> In LILOG we use DRSs for text representiLtions.</Paragraph>
    <Paragraph position="2"> But we deviate front the cla.~sicM Dl~F-style in using one-placc event predicates and thematic roles instead of n-place ew;nt predicates. A second difference is given \]W the fact that in L1LOG DllSs come with all indcx. The index is the list of reference tinles available with respect to the DRS ill question. For a simple sentence it will bc a list consisting only of one element - the DRF of the event introduced - for a text it will lie a COmlllcx list, tit(: T-list.</Paragraph>
    <Paragraph position="3"> So, for instance, the LIL()G-DILS for cominy o\]x can be illustrated i~s follows:</Paragraph>
    <Paragraph position="5"> For the \])ITS to be valid there must exist an embedding function which nmps e onto an event of the model structure such that e satisfies tile conditions as described ill the I)RS.</Paragraph>
