A COORDINATION SCHEMA IS DESCRIBED WHICH HAS BEEN INTRODUCED IN THE "MITRE" GRAMMAR. THIS SCHEMA DEALS WITH THE TYPE OF COORDINATION WHERE A SINGLE SENTENCE OF TWO OR MORE CONSTITUENTS ALLOWS FOR A PARAPHRASE OF TWO OR MORE SEPARATE SENTENCES WHICH ARE IDENTICAL IN EVERY RESPECT EXCEPT FOR THE CONJOINABLE MEMBERS. THE NEW APPROACH…

A CLASS OF TRANSFORMATION GRAMMARS IS DEFINED AND A COMPUTER PROGRAM FOR SENTENCE ANALYSIS IS DESCRIBED AND DOCUMENTED WITH RESPECT TO THIS CLASS. THE PROGRAM EXISTS IN PURE LISP FORM AND IN MIXED LISP AND IBM 7090 ASSEMBLY LANGUAGE FORM. THE PAPER CONTAINS INFORMATION TO PERMIT THE USER TO WRITE HIS OWN TRANSFORMATIONAL GRAMMAR. COMPUTER PROGRAM…

This is a report on the activities of the survey of spoken English at the University of Lund (Sweden), during the period 1975-81. The aim of the survey has been to make available in machine-readable form a corpus of material with its origin in speech. The corpus was built in conjunction with the survey of English usage project at the University of…

The papers in this volume describe computer runs with six different transformational grammars, in each case using the computer system for transformational grammar described in AL 002 220. They are collected as examples which, it is hoped, will encourage other linguistics to use the system. The motivation for the first three projects described was…

The Commission of the European Communities has acquired an automatic translation system (SYSTRAN), which has been put into operation on an experimental basis. The system covers translation of English into French and comprises a dictionary for food science and technology containing 25,000 words or inflections and 4,500 expressions. This report…

A procedure, designated "MORPH," has been developed for the automatic morphological analysis of complex English words. Each word is reduced to a stem in canonical or dictionary form, plus affixes, inflectional and derivational, represented as morphemes or as syntactic features of the stem. The procedure includes the task of analyzing as…

The inventory presented here was produced by listing 13 sentence elements (subject, object, etc.) with specifications as to mutual exclusiveness and then presenting them to a computer with a request for permutations. Those items for which no examples could be found were excluded from the output, and the remaining patterns constitute the inventory…

This is a description of the motivation and overall organization of the OWL language for knowledge representation. OWL consists of a linguistic memory system (LMS), a memory of concepts in terms of which all English phrases and all knowledge of an application domain are represented; a theory of English grammar which tells how to map English…

The report documents performance on a 24-month R&D effort oriented toward the development of a computerized model for machine translation of natural languages. The model is built around a set of procedures called verbalization, intended to stimulate the processes employed by a speaker or writer in turning stored information into words.…

Chapter I, an introduction to machine translation of languages, contains a simplified description of electronic computing machines, and a discussion of the advantages and disadvantages of machine translation research. A historical background of machine translation of languages is given, together with a description of various machine translation…

The use of a system for on-line conversation in ordinary English grammatical patterns is illustrated by a number of examples showing how data bases of diverse content and structure may be described, interrogated, and modified. It is suggested that a system composed of a user extendable subset of English, a natural language compiler to translate…

The second version of the Multistore Sentence Analysis System, implemented on an IBM 360/65, uses a correlational grammar to parse English sentences and displays the parsings as hierarchical syntactic structures comparable to tree diagrams. Since correlational syntax comprises much that is usually considered semantic information, the system…

A research program was planned to develop a first, experimental computer-assisted instruction system that would permit interaction with students in a subset natural English. At the base of this system was a model of cognition that would represent the knowledge content of the material to be taught and the student's current knowledge of it. A…

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…

This study was conducted to provide descriptive, comparative, quantitative, and statistical information on the syntactic characteristics of two English registers: (1) formal and informal discussion and (2) administrative correspondence. In chapters 1 and 2 the background and purpose of the study are discussed. The composition of the major spoken…
