Cohesion in Computer Text Generation: Lexical Substitution

Abstract

This report describes Paul, a computer text generation system designed to create cohesive text. The device used to a achieve this cohesion is lexical substitution. Through the use of syntactic and semantic information, the system is able to determine which type of lexical substitution will provide the necessary information to generate an understandable reference, while no providing so much information that the reference is confusing or unnatural.
