The paper presents an algorithm, written in PROLOG, for processing English sentences which contain either Gapping, Right Node Raising (RNR) or Reduced Conjunction (RC). The DCG (Definite Clause Grammar) formalism (Pereira & Warren 80) is adopted. The algorithm is highly efficient and capable of processing a full range of coordinate constructions containing… (More)
The paper claims that the right attachment rules for phrases originally suggested by Frazier and Fodor are wrong, and that none of the subsequent patchings of the rules by syntactic methods have improved the situation. For each rule there are perfectly straightforward and indefinitely large cl asses of simple counterexamples. We then examine suggestions by… (More)
Machine translation systems can gain wider application if they can be operated in a monolingual environment. To design such systems, the major issue is how to assure the user that the translation is correct without understanding either the source or the target language. This paper first discusses the various approaches to assuring correct translation in a… (More)
The paper is a description of a parallel model for natural language parsing, and a design for its implementation on the Hype,'eube multiproeessor. The pm'allel model is based on the Semantic Definite Clause Grammar formalism and integrates syntax and semantics through the commmfication of processes. The main proeessess, of which there are six, contain… (More)
Prosody can be useful in resolving certain lexical and structural ambiguities in spoken English. In this paper we present some results of employing two types of prosodic information, namely pitch and pause, to assist syntactic and semantic analysis during parsing.
