A Strategy for Dynamic Interpretation: a Fragment and an Implementation

The strategy for natural language interpretation presented in this paper implements the dynamics of context change by translating natural language texts into a meaning representation language consisting of (descriptions of) programs, in the spirit of dynamic predicate logic (DPL) [5]. The difference with DPL is that the usual DPL semantics is replaced by an error state semantics [2]. This allows for the treatment of unbound anaphors, as in DPL, but also of presuppositions and presupposition projection. The use of this dynamic interpretation strategy is demonstrated in an implementation of a small fragment of natural language which handles unbound pronoun antecedent links, where it is assumed that the intended links are indicated in the input string, and uniqueness presuppositions of definite descriptions. The implementation consists of a syntax module which outputs parse trees, a semantic module mapping parse trees to DPL representations, a representation processor which determines tr...
