SAMPLE OUTPUT SENTENCES OF VARIOUS COMIT AND SNOBOL PROGRAMS FOR TESTING A CHINESE GENERATIVE GRAMMAR ARE PRESENTED. THE GRAMMAR CHOSEN FOR EXPERIMENTATION IS A PRELIMINARY VERSION OF A TRANSFORMATIONAL GRAMMAR. ALL OF THE COMIT PROGRAMS AND ONE OF THE SNOBOL PROGRAMS USE A LINEARIZED REPRESENTATION OF TREE STRUCTURES, WITH ADDITIONAL NUMERICAL…

PRESENTED IN THIS PAPER IS A SIMPLIFIED DESCRIPTION OF AN ALGORITHM FOR TRANSFORMATIONAL ANALYSIS OF ENGLISH SENTENCES. IT IS NEITHER ASSUMED NOR IMPLIED IN THIS ALGORITHM THAT ANY KIND OF PRIOR ANALYSIS (EITHER STRING OR CONSTITUENT ANALYSIS) IS REQUIRED AS A PREREQUISITE. IN ORDER TO DEFINE THE SET OF ALL TRANSFORMS, THE AUTHORS FIRST DEFINE A…

The augmented transition network described in this report was developed in the course of work in semantic interpretation in the context of a computer system which answers English questions. In order to provide mechanical input for the semantic interpreter, a parsing program based on the notion of a "recursive transition network grammar" was…

RESEARCH IN THREE AREAS OF COMPUTATIONAL LINGUISTICS IS DESCRIBED--(1) THE DESIGN AND DEVELOPMENT OF A TRANSFORMATIONAL GRAMMAR FOR A SUBSET TO GRAMMATICAL SENTENCES IN ENGLISH, (2) THE IMPLEMENTATION OF THIS GRAMMAR IN TERMS OF A SENTENCE SYNTHESIZING PROGRAM WRITTEN IN LISP 1.5, AND (3) THE USE OF SENTENCE SYNTHESIZING PROGRAMS FOR…

SCIENTIFIC REPORT NO. 1 OF THIS PROJECT CONTAINS FOUR PARTS. THE FIRST, BY P. ROSENBAUM AND D. LOCHAK, PRESENTS AND EXPLAINS THE "IBM CORE GRAMMAR OF ENGLISH" AND GIVES A SET OF 66 DERIVATIONS CONSTRUCTED IN TERMS OF THE CORE GRAMMAR. PART II, "DESIGN OF A GRAMMAR TESTER" BY D. LIEBERMAN, SUMMARIZES THE DESIGN CONSIDERATIONS OF…

The first section of this paper deals with the attempts within the framework of transformational grammar to make semantics a systematic part of linguistic description, and outlines the characteristics of the generative semantics position. The second section takes a critical look at generative semantics in its later manifestations, and makes a case…

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 PAPERS IN THIS VOLUME--CATEGORIZED AS EITHER (1) AUTOMATIC ANALYSES OF NATURAL LANGUAGES, (2) STATISTIC AND SEMANTIC ANALYSES OF LINGUISTIC DATA, OR (3) ALGEBRAIC THEORIES OF LANGUAGES--ARE THE COLLECTIVE PRODUCT OF THE INTERNATIONAL CONFERENCE ON COMPUTATIONAL LINGUISTICS HELD AT GRENOBLE, FRANCE, AUGUST 23-25, 1967. TOPICS RANGE FROM…

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…

The objective of this thesis was to colligate the various strands of research in the literature of computational linguistics that have to do with the computational treatment of semantic content so as to encode it into a computerized dictionary. In chapter 1 the course of mechanical translation (1947-1960) and quantitative linguistics is traced to…

This is an attempt to compile, from public sources, as complete a bibliography as possible of works related to linguistics and having to do with transformational generative grammar. The arrangement is alphabetical by author and chronological by publication or delivery date of works of a given author. The majority of items are also indexed by…

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…

There is a need for a new kind of linguistic theory which, while being concerned with both generation and analysis, must include the roles of memory, non-linguistic knowledge, and inference. The role of logic is diminished according to such a theory because inference has no real logical content. Meaning must be studied with respect to the actual…

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…
