This report describes Phase 1 of a research project with the over-all objective of exploring the applicability of automatic methods in the indexing of drug information appearing in English natural language text. Two major phases of the research have been completed: (1) development of the automatic indexing method and its implementation on the test…

This report describes the searching methods and the search program for the automatic indexing method which was developed and implemented in an earlie r phase of the project. The indexing method generates index tags automatically from English language text and creates a machine searchable file of index records for the document being processed.…

This report presents the results of the initial phase of the File Organization Project, a study which focuses upon the on-line maintenance and search of the library's catalog holdings record. The focus of the project is to develop a facility for research and experimentation with the many issues of on-line file organizations and search. The first…

Microfiche storage and computer-assistance to produce multilingual indexes at the United Nations Headquarters Library are described. (Author/NH)

Improvements in the technology associated with the information sciences will have their primary potential impact on the distribution of costs, information flow level, information availability, and use among information channels. This improvement implied not only a capability to perform a given function, but a lower cost. For example, the trend…

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)

Paper presented at the Second International Conference on Linguistics and Translation, October 4-7, 1972, Montreal, Canada. (DD)

Relates office automation to its application in libraries, discussing computer software packages for microcomputers performing tasks involved in word processing, accounting, statistical analysis, electronic filing cabinets, and electronic mail systems. (EJS)

STARTING FROM A MODEL OF CONTEMPORARY MECHANIZED RETRIEVAL SYSTEMS AND THE CHARACTERISTICS OF INDEXING LANGUAGES USED THEREIN, THE AUTHORS DEVELOP A RATIONAL BASIS FOR USE OF THE UNIVERSAL DECIMAL CLASSIFICATION (UDC) IN THIS CONTEXT. PRACTICAL DESIGN CONSIDERATIONS FOR THE USE OF UDC IN A MECHANIZED RETRIEVAL SYSTEM ARE DISCUSSED. EXAMPLES ARE…

This report describes work concerned with the statistical evaluation of the output of MEDICO automatic indexing procedure. The statistical tests were designed to examine the validity of the assumptions which formed the bases of the indexing algorithms with primary emphasis on the algorithm development for the computation of weights and links. Some…

A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional…

The broad objective of this investigation was to explore the potential and applicability of automatic methods for the indexing of drug-related information appearing in English natural language text and to find out what can be learned about automatic indexing in general from the experience. More specific objectives were the development,…

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…

Based on the principle that alphabetical arrangement should be based on the characters actually appearing in the sort field, a computer filing code was produced which provides rules for formatting entries for computer manipulation. This study applies the principles developed in that code to library subject headings, using a sample of the Library…

TWO PROJECTS ON THE DESIGN, DEVELOPMENT, IMPLEMENTATION, AND EVALUATION OF A MAN-MACHINE SYSTEM FOR COUNSELING IN THE PALO ALTO AND LOS ANGELES SCHOOL DISTRICTS ARE REPORTED. THE EARLIER PHILCO 2000 COMPUTER PROGRAMS SIMULATED A COUNSELOR'S WORK IN THE EDUCATIONAL PLANNING INTERVIEW BY ACCEPTING INPUTS SUCH AS SCHOOL GRADES, TEST SCORES, AND…
