This report documents efforts over a five-month period toward completion of a pilot system for machine translation of German scientific and technical literature into English. The report is divided into three areas: grammar formalism, programming, and linguistics. Work on grammar formalism concentrated mainly on increasing the power of the…

Noam Chomsky's transformational-generative grammar model may effectively be translated into an equivalent computer model. Phrase-structure rules and transformations are tested as to their validity and ordering by the computer via the process of random lexical substitution. Errors appearing in the grammar are detected and rectified, and formal…

In generating sentences by means of a transformational grammar, it is necessary to analyze trees, testing for the presence or absence of various structures. This analysis occurs at two stages in the generation process--during insertion of lexical items (more precisely, in testing contextual features), and during the transformation process, when…

The system described in this report is designed for use as a computational tool that allows a linguist to develop and study methods for generating surface strings from an underlying semantic structure. Initial findings with regard to form-determiners (such as voice, form, tense, and mood), some rules for embedding sentences, and some attention to…

This report describes work on a pilot system for a fully automatic, high-quality translation of German scientific and technical text into English and gives the results of an experiment designed to show the system's capability to produce quality mechanical translation. The areas considered were: (1) grammar formalism, mainly involving the addition…

Section I of this report discusses the theoretical issues relating to the development of syntax recognition routines based on psychological models of human speech recognition and reviews the relevant psychological literature. The research reported deals with attempts to relate various syntactic variables to measures of the perceptual complexity of…

The 2,459 entries in this bibliography on transformational grammar and related areas are written in, and deal with, a wide variety of languages. The listings, covering available publications up to early 1968, include texts, journal articles, papers and other works, and reviews of some of the more outstanding writings. (AMM)

A set of procedures for testing hypotheses about the syntactic structure of natural languages has been developed for use on-line with computer display consoles. The procedures were designed in the context of Chomsky's transformational generative grammar. A linguist can construct phrase structure trees, selecting with the lightgun from alternative…

The course in parsing English is essentially a survey and comparison of several of the principal systems used for understanding natural language. The basic procedure of parsing is described. The discussion of the principal systems is based on the idea that "meaning is procedures," that is, that the procedures of application give a parsed…

The report documents progress and results of a 2-1/3 year effort to further the prototype Chinese-English Machine Translation System. Additional rules were incorporated into the existing grammar for Chinese analysis and interlingual transfer, with emphasis on the latter. CHIDIC was updated and revised. Approximately 16,000 new entries were added…

This review of Bever's psycholinguistics survey is for the most part favorable. Commentary is centered on sections 1, 2, 4, and 6 of the report. The survey's first part is judged significant in that Wundt's pioneering work in psycholinguistics is discussed. The second section, on grammar as a psychological process, is found obscure in its…

This paper defines the structure of a semantic network for use in representing discourse and lexical meanings. The structure is designed to represent underlying semantic meanings that, with a lexicon and a grammar, can generate natural-language sentences in a linguistically justifiable manner. The semantics of natural English can be defined as a…

This survey consists of eleven papers covering current topics within the realm of linguistic science. The papers are written by scholars in particular fields, and each one is followed by a list of references and critiques by other linguists. Current theories are discussed and reference is made to recent studies and writings. The areas of…

This paper describes the notation and underlying organization of an augmented, recursive-transition network grammar and illustrates how such a grammar is a natural medium for expressing and explaining a wide variety of facts about the psychological processes of sentence comprehension. A general discussion of transformational grammar and…

This paper describes a system for the computer understanding of English. The system answers questions, executes commands, and accepts information in normal English dialogue. It uses semantic information and context to understand discourse and to disambiguate sentences. It combines a complete syntactic analysis of each sentence with a heuristic…
