The learning machine described in this paper acquires concepts representable as conjunctive forms of the predicate calculus and behaviors representable as productions (antecedent-consequent pairs of such conjunctive forms): these concepts and behavior rules are inferred from sequentially presented pairs of examples by an algorithm that is probably…

The role of lexicometry is to furnish statistical data on all measurable aspects of vocabulary. This study presents an inventory of works on the choice of elements of the German language and outlines the methods of compiling vocabulary with specific reference to the method of choosing words useful for the teaching of a language. It also attempts…

This bibliography is a selected listing of approximately 775 books, monographs, journal articles, collections, bibliographies, and unpublished papers on linguistics and the uncommonly taught languages. It includes 119 documents entered by th e ERIC Clearinghouse for Linguistics in the ERIC system in 1967 as well as items which have appeared since…

This project was designed to develop machine-searchable files of linguistic data to be interrogated by researchers looking for patterns, examples, and other kinds of evidence bearing on language universals. This preliminary report of the project focuses on a detailed description of the computer program system used, MARC (Machine-Readable Catalog),…

This paper describes a large computer-coded conversational speech data base and results of testing phonological rules on that data base. The study shows that frequency of rule application depends not only on phonological environments, but also on frequency of occurrence of specific words. That is, some rules are highly word-dependent, others are…

This paper attempts to characterize some of the knowledge that people have of their language's semantic structure, in order to determine what a computer has to know to perform the operations of searching for facts and answering questions. Necessarily, this sort of semantic analysis is done in connection with syntactic structure. The meaningful…

When a grammar is expressed in augmented transition network (ATN) form, the problem of detecting syntactic ambuguity reduces to finding all possible paths through the ATNs. Each successfully terminating path through the ATN generates an acceptable parsing of the input string. Two ATN forms, minimal-node and pseudo-tree, are described along with…

The first part of this dissertation is a metatheoretical discussion of the needs and means of semantic analysis. This discussion includes sections on metalanguage, deep and surface structure and structural semantics, and procedures for relating the English of abstracts to a classification concordance in the same language. The second part describes…

Language teaching requires textbook material that contains the most frequent concepts of a language. The computer brings its tremendous information processing ability to the task of establishing word frequency rankings, but the computer is limited to counting word-forms and not semantic concepts. The most recent word frequency dictionaries, in…

This is the tenth report in the Language Research In Progress (LRIP) series, superceding reports 1-9. LRIP 10 lists 469 language-related research projects in progress between November 1969 and June 1970 for which documentation is available. The report is indexed by topic, principal investigator, and location of the project in the United States or…

The papers reprinted in this volume carry out the "distributional method," i.e., the analysis of occurrence restrictions, beyond phonemics. This methodological approach, of defining more freely combining new elements on the basis of occurrence restrictions of old elements, has proved applicable in many situations in structural…

This paper presents the theoretical changes that have developed in Conceptual Dependency Theory and their ramifications in computer analysis of natural language. The major items of concern are: the elimination of reliance on "grammar rules" for parsing with the emphasis given to conceptual rule based parsing; the development of a…

This final report of a study which developed a working corpus of spoken and written Portuguese from which syntactical studies could be conducted includes computer-processed data on which the findings and analysis are based. A data base, obtained by taping some 487 conversations between Brazil and the United States, serves as the corpus from which…

When it is published in four or five years, the "Dictionary of American Regional English" (DARE) will be the official dictionary of the American Dialect Society. This dictionary will contain information concerning vocabulary, pronunciation, and grammatical forms which are restricted regionally or socially in American speech. One…

Gives a short grammar of the Lisp computer language. Presents an introductory English parser (Simparse) as an example of how to write a parser in Lisp. Lists references for further explanation. Intended as preparation for teachers who may use computer-assisted language instruction in the future. (LMO)
