The report very briefly summarizes the research performed during the contract period March 1, 1964, to February 28, 1971. The emphasis of the research was on the discovery and development of techniques for automatically indexing and classifying documents. The research was limited to statistical techniques rather than semantic or syntactic. A…

Reported are the hearings held on April 29 and 30, 1969 before the General Subcommittee on Education of the U.S. House of Representatives on H.R. 8809, a bill to amend Title IX of the National Defense Education Act of 1958 to provide for the establishment of a national information retrieval system for scientific and technical information. The…

The aim of this bibliography is to provide a guide to the diverse body of literature that deals with the "geographic or spatial characteristics" of the data elements and data items in each of the following five phases: (1) Specification, (2) Acquisition, (3) Processing, (4) Dissemination and (5) Application. It is intended to provide…

Detailed descriptions of the data analysis procedures used in Project EDNEED (Empirical Determination of Nationally Essential Educational Data) are contained in this volume, the last of a five-volume final report. Results of the application of procedures and a narrative interpretation of the results are included. Priority rankings of 323 questions…

Authors examines the limits of selective attention during early stages of information processing. (Author/RK)

The present investigation was undertaken to study the relation of one component of intonation or stress, namely, rhythmic temporal patterns, to the production of utterances.It is hypothesized that the rhythmic schema of an utterance contains information that delimits the possible syntactic forms of that utterance. (Author)

Two different experimental procedures were used to examine (a) information-processing differences between two groups of subjects (Cs versus Vs) identified by the form of their conditioned eyeblinks; (b) information-processing differences between the right and left cerebral hemispheres; and (c) parallels between hypothesized C-V differences and…

The information circuit described was devised to compare data from the stages of production, stocks completed, scheduling, broadcasting, and viewer behavior. A model of the internal activities of this process is provided, and the resulting computerized analysis is discussed. (RAO)

Describes a systematic approach to the design of fixed-length, derived, truncated search keys for corporate author records; and a statistical method for predicting the performance of search keys for files of arbitrary size. (VT)

Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document. (VT)

An exposition of reasons why a system of automatic translation could not use a terminology bank except as a source of information. The fundamental difference between the two tools is explained and examples of translation and mistranslation are given as evidence of the limits and possibilities of each process. (Text is in French.) (AMH)

Noting the scarcity of programs in communication technology, the author discusses the nature of communication and types of communication processes (particularly those involving technology) to help the curriculum developer in creating a well-designed program. He then describes three model approaches he has successfully used in designing…

A typical school spelling task is analyzed in terms of an information processing model of spelling performance. (Author)

Describes how several computer programs can be of assistance to educators in teaching news writing and in informing students about newsroom information processing. (KS)

An examination of one of the problems of data banks dealing with terminology and serving varieties of users. The problem addressed is: Do such data banks actually fulfil their objective, and, if not, what modifications should be made? Difficulties experienced by translators are discussed.
