Recognizing that the use of resource sharing capabilities provided by computer networks is inhibited by the requirement that the user become familiar with the varied command languages and protocols of each accessed system, this report presents a general approach to solving the problem using an intermediary system to support a set of common…

Based on a series of studies performed by ERIC/Information Resources staff and consultants which focused on the activities of over 40 experienced online searchers, this report offers the following suggestions for enhancing certain online retrieval system features and making improvements in ERIC vocabulary: (1) the implementation of an online…

A PLAN FOR THE DEVELOPMENT OF A COORDINATED INFORMATION PROGRAM FOR GEOLOGICAL SCIENTISTS IN THE UNITED STATES IS DISCUSSED IN DETAIL IN THIS REPORT. THE AMERICAN GEOLOGICAL INSTITUTE APPOINTED A COMMITTEE ON SCIENCE INFORMATION TO DEVELOP A NEW NETWORK FOR COMMUNICATION. THE NEED AROSE FROM A REALIZATION OF SEVERAL DEFICIENCIES OF PRESENT…

THE SECOND CUMULATIVE EDITION OF THE EDUCATIONAL RESOURCES INFORMATION CENTER/CLEARINGHOUSE ON THE RETRIEVAL OF INFORMATION AND EVALUATION IN READING (ERIC/CRIER) INFORMATIONAL PUBLICATIONS INCLUDES THREE NEWSLETTERS AND THREE INFORMATION BRIEFS. THE NEWSLETTERS PRESENT DISCUSSIONS OF THE ERIC/CRIER DOCUMENT PROCESSING FOR RESEARCH IN EDUCATION,…

CHEMICAL ABSTRACTS SERVICE (CAS), IN CONJUNCTION WITH THE NATIONAL SCIENCE FOUNDATION, CONDUCTED THE FIRST PUBLIC DEMONSTRATION OF CAS COMPUTER-BASED SUBSTRUCTURE SEARCH TECHNIQUES AT THE 152ND MEETING OF THE AMERICAN CHEMICAL SOCIETY IN NEW YORK CITY. FROM SEPTEMBER 11 THROUGH SEPTEMBER 16, 1966, INTERESTED PERSONS WERE GIVEN THE OPPORTUNITY TO…

THIS PAPER IS A CASE STUDY OF THE ADOPTION BY GEOSCIENCE ABSTRACTS OF UNIDEK, A COMPUTER-COMPILED SYSTEMATIC SUBJECT INDEX BASED ON THE UNIVERSAL DECIMAL CLASSIFICATION (UDC). EVENTS LEADING TO A DECISION TO ADOPT THE SYSTEM, SOME THEORY OF INDEXES, PROBLEMS INVOLVED IN CONVERSION, AND SOME OF THE RESULTS ACHIEVED ARE REVIEWED. UNIDEK MAKES…

EASY ENGLISH IS A NATURAL COMMAND LANGUAGE DESIGNED TO SIMPLIFY COMMUNICATION BETWEEN MAN AND MACHINE THROUGH A REMOTE TYPEWRITER CONSOLE. IT IS MADE UP OF READILY RECONIZED SENTENCES OF THE ENGLISH LANGUAGE, SENTENCES WHICH ANY LAYMAN MIGHT BE EXPECTED TO USE IN EVERYDAY REQUESTS FOR SERVICES OR ARTICLES FROM A FAMILIAR SOURCE. EASY ENGLISH WAS…

THIS PAPER DESCRIBES A METHOD (SCHEME) FOR THE DEVELOPMENT OF A VOCABULARY IN THE FIELD OF CHEMICAL PHYSICS FROM PRIMARY JOURNAL ARTICLES. ALL TERMS APPEARING IN A RECENT JOURNAL (VOL. 39, JOURNAL OF CHEMICAL PHYSICS) JUDGED TO BE IMPORTANT WERE DIVIDED INTO THREE CATEGORIES--(1) PROPERTIES, PROCESSES, PHENOMENA, (2) OBJECTS, INCLUDING SYSTEMS AND…

This report explains the following mathematical techniques which may be used for relating search requests to documents contained in a library: (1) Boolean Algebraic Retrieval, (2) Linear Statistical Retrieval, (3) Statistical Association Techniques for expanding a query and/or for expanding the set of retrieval documents, (4) Vector Space…

An efficiency model and a performance function are presented in this technical report. The efficiency model has been tailored to the needs of an information retrieval system while remaining consistent with established economic procedures. The performance function allows for the comparison of several information retrieval systems. A sample…

This report outlines a generalized storage scheme for large files of highly structured data, or catalogs, and describes their realization on magnetic tape. Each datum, large or small, is assigned to one of a number of data classes of which a user may define any number. The over-all organization of a catalog is given by a map that imposes a tree…

This collection of search formulations was assembled to assist in Dialog Searching of the ERIC data base. The formulations represent modular building blocks or concepts that occur frequently when searching this file. They have been formulated and described in such a way that they can be used as given, or they can be modified to suit specific…

The monograph presents a classification system of vocational rehabilitation program evaluation technology and literature intended to be useful for the efficient retrieval of program evaluation information and to provide greater communication among rehabilitation personnel. The classification system's purpose is to control the nuances of expression…

This annotated bibliography is an effort to provide educators and researchers with a comprehensive listing of current resources, information, and research concerning peer and cross age academic tutoring by students, together with a selection of references on related topics of cross age interactions, tutoring in general, and the use of…

An experiment was conducted to identify some of the important parameters affecting search time, a critical cost factor in retrieval systems. Using actual computer searches of Chemical Abstracts Condensate, a comparison was made between the effectiveness of linear and inverted filing systems. Since the results indicated that it was the type and…
