Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

Working toward the goal of an automatic indexing system which is truly competitive with human indexing in cost, time and comprehensiveness the Machine-Aided Indexing (MAI) process was developed at the Defense Documentation Center (DDC). This indexing process uses linguistic techniques but does not require complete syntactic analysis of sentences…

The KWAC Index Generation Program was implemented at the State University of New York at Buffalo. It consists of only 252 statements for the COBOL Compiler Edition V310222 on the CDC6400 computer under the KRONOS operating system in the batch mode. The KWAC program is essentially a KWIC index generator designed for a special purpose for use in a…

Questions of the automation of input, output and data processing on computers in systems of information services are covered in the discussion of peculiarities of applied computers and processed information, general characteristics of processing algorithms and problems of information input and output. This is followed by a discussion of the…

A research project carried out a survey of operational software designed to produce printed subject indexes and measured the human and machine costs of producing such indexes. (PF)

Describes the use of FAMULUS, a database management system, to teach library science students at Case Western Reserve University indexing, computerized file construction, and online information retrieval. The special features of FAMULUS and their use in course instruction are outlined and evaluated. A 19-item reference list is attached. (Author/JL)

In order to contribute to the success of several studies for automatic classification, indexing and extracting currently in progress, as well as to further the theoretical and practical understanding of textual item distributions, the development of a frequency program capable of supplying these types of information was undertaken. The program…

An operational, comprehensive, economical method for updating and correcting entries in a computerized bibliographic system is presented. The technique was developed in connection with the East African Agricultural Bibliographic Project at West Virginia University. Data modification operations are discussed as well as the limitations of the method…

The objectives of this study were: (1) to create a set of computer programs capable of practical associative processing of NASA's growing document collection, (2) to process the collection with these programs, exhibiting the achievement of a capability to perform associative search of the collection, and (3) to study the use of statistical…

What is the desirability and usefulness of different thesaurus displays used either singly or in groups? Is an alphabetical listing of terms with cross references more useful to an indexer than a complete hierarchical display? Is the permuted or the rotated term index more useful to the indexer or retriever? Is an alphabetical display along with a…

Describes an automatic display system which has been developed for the editing of concept subnetworks within a relational index and which employs only a floppy diskette drive and a PET 2001 microcomputer. Appendices on Farradane's Nine Relations and on the Graphic Editing System Commands and a reference list are included. (Author/JL)

CONTENTS--(1) AN ASSOCIATIVITY TECHNIQUE FOR AUTOMATICALLY OPTIMIZING RETRIEVAL RESULTS BY RONALD R. ANDERSON. AN ASSOCIATIVE TECHNIQUE BY WHICH IT IS POSSIBLE TO AUTOMATICALLY EXPAND AND NARROW THE NUMBER OF DOCUMENTS RETRIEVED AND TO RETRIEVE DOCUMENTS RELATED TO A REQUEST EVEN THOUGH THEY MAY NOT BE INDEXED BY THE EXACT TERMS OF THE REQUEST IS…

To support studies in automatic indexing, classification and extracting, a general purpose frequency program was developed to further theoretical and practical understanding of text word distributions. While the program is primarily designed for counting strings of character-oriented data, it can be used without change for counting any items which…

THE OBJECTIVE OF THIS PROJECT WAS TO DEVISE AN ALGORITHM FOR A STEM RECOGNITION PROGRAM DESIGNED TO SEARCH FOR THE ROOT OF ANY HEBREW WORD AS WELL AS TO DETECT INNER CHANGES ON THE GIVEN ROOT. SUCH AN ALGORITHM COULD BE USED IN LIBRARY CATALOGING AND IN CREATING INDEXES AND CONCORDANCES OF TEXTS IN THE HEBREW LANGUAGE. IN THIS STUDY THE HEBREW…
