Integrating Syntax, Semantics, and Discourse DARPA Natural Language Understanding Program

Abstract

The conjunction mechanisms has been extended to allow semantic as well as syntactic processing of conjoined structures. The meta-conjunction component, which automatically generates conjunction rules for a grammar, has been enhanced so that it also generates rules describing the appropriate input to semantics, the intermediate syntactic representation or ISR, for each conjoined structure that is parsed. The modules which interpret and simplify the ISR have been extended so that the ISR for elements which are syntactically null under conjunction, but which have non-null semantics, can be computed. The semantics has been given a recursive structure so it can call itself to analyze the separate conjuncts of a conjoined structure.
