Semantic theories of natural language as- sociate meanings with utterances by pro- viding meanings for lexical items and rules for determining the meaning of larger units given the meanings of their parts. Traditionally, meanings are com- bined via function composition, which works well when constituent structure trees are used to guide semantic com- position. More recently, the functional structure of LFG has been used to pro- vide the syntactic information necessary for constraining derivations of meaning in a cross-linguistically uniform format. It has been difficult, however, to recon- cile this approach with the combination of meanings by function composition. In contrast to compositional approaches, we present a deductive approach to assem- bling meanings, based on reasoning with con...
