(3) 7 ‘The algorithm must represent the temporal information that is contained in the tense of a sentence and in its temporal adverb (if there is one).’ Kamp & Reyle (1993: 512) 8 ‘…[the feature] TENSE has three possible values, past, present, and future, signifying that the described eventuality lies before, at, or after the utterance time, respectively. The value of TENSE for a given sentence S is determined by the tense of the verb of S. When the main verb is in the simple past, TENSE = past; when it is in the simple present, TENSE = pres; and when the verb complex contains the auxiliary will, TENSE = fut.’ Kamp & Reyle (1993: 512-513) 9 (5) (6) Tom plays with the Cambridge Philharmonia.

The representation of the truth-conditional content is a merger of information from (i) word meaning and sentence structure, (ii) conscious pragmatic processes, and (iii) default meanings. Merger representation. 14 Default Semantics uses an adapted and extended formalism of DRT but applies it to the output of the merger of these sources of meaning. 15 (1) Mary will go to the opera tomorrow night.

It can be translated into the DStheoretic operator ACCΔn. 28 Conclusions The general notion of modality (Acc) subsumes various expressions of futurity (rf, fp, tf). It can be translated into the DStheoretic operator ACCΔn. ACCΔn, combined with CD and CPI 1, allows for representing the degrees of modality and the degrees of informative intentions associated with the acts of communication that make use of these different forms. 29 Pragmatic composition view: ‘…even if the semantic value of a word is fixed by language (and context, if saturation is necessary), composing it with the semantic values for other words often requires help from above [top-down process, KJ]. It is semantic composition which has a fundamentally pragmatic character.’ Recanati (2003:139). 30 Merger representations are compositional. They are mental representations that are coarse-grained equivalents of thoughts. 31 Merger representations are compositional. They are mental representations that are coarse-grained equivalents of thoughts. Merger representations have truth conditions. 32 Merger representations are compositional. They are mental representations that are coarse-grained equivalents of thoughts. Merger representations have truth conditions. Default Semantics applies the amended and extended DRT mechanism to merger representations (e.g. incorporation of the operator on eventualities ACC e) 33 A disclaimer: Interactive Default Semantics is not an alternative to DRT: it uses its tools ‘one level higher’, to the analysis of acts of intentional communication. Compositionality is predicated of the representations of these acts. 34 K.M.
