.... argument, one can state that additional relations hold for this discourse referent: T : t Direction(t) T (t) x; y: has dir(x; y) y: t has dir(t; y) Direction(t) 4 Functional application of terms to the problem of composing DRS is described in detail in [Kus96] or [FGG96]. 5 In our discussion, we eliminate the first step: The word sequence a flight is considered to be a noun phrase (as it is the combination of a determiner and a noun) and the proper noun Athens is seen as a noun phrase, as well. 6 An Inference Based Approach to the Interpretation of Discourse ....

....representation of the left hand side of each rule is defined by functional application of the representations of the right hand side parts as specified in the term assigned to every rule. Functional application of terms to the problem of composing DRS is described in detail in [Kus96] or [FGG96]. We will explain the construction of the DRS for the whole utterance a flight to Athens by describing the bottom up parsing process that in parallel to the syntactic analysis constructs the desired semantic representation. Starting from the lexical entries, the word sequence a flight is ....

....component to communicate system utterances to the user. In this paper, we address in detail the issue of semantics construction during parsing natural language input . As will be shown in section 3, the backbone of our incremental approach to composing semantic representations is # DRT [Fis96]: The parser builds Discourse Representation Structures (DRS) KaR93] incrementally, and after each composition step, the satisfiability with respect to a given knowledge base is verified by an ABox consistency test. For this purpose, we exploit the fact that DRSs can be mapped onto ABoxes. In ....

....Semantic evaluation. The DRS obtained by the semantic construction step has to be evaluated w.r.t. resolution of references, in particular of anaphors, and DRT specific operators. For anaphor resolution, we developed a computational framework based on linguistic and pragmatic heuristics in [Fis96] . DRSs may contain logical operators, e.g. disjunction and conditional expressions and so called duplex conditions representing natural language quantifiers. Evaluating such DRSs means to apply certain transformations to them. Disjunction will lead to two alternative DRSs. For quantifiers, ....
