An Intelligent Analyzer and Understander of English The paper describes a working analysis and generation program for natural language, which handles paragraph length input. Its core is a system of preferential choice between deep semantic patterns, based on what we call "semantic density." The system is contrasted: (1) with syntax oriented linguistic approaches, and (2) with theorem proving approaches to the understanding problem.
