The report is presented in two parts. The first examines the social and technical implications of information systems vis a vis the individual's ability to control the dissemination of information about himself. It is argued that information systems must incorporate certain properties in their initial design in order to safeguard man's…

The document contains an outline of a course developed for an adult class meeting five hours per week for 18 weeks. The objectives of the course are to develop: an appreciation of the growing uses of automatic data processing; an entry level job proficiency in the operation of the keypunch machine; work habits conducive to job proficiency; and…

General Information Storage, Retrieval, and Application System (GENIRAS) is a computer-aided information system designed for the storage, retrieval, and manipulation of data files. The system gives the user (1) flexibility in defining and using data bases, (2) a wide range of procedures to be applied to the data, and (3) a variety of acceptable…

Two essential components of the information-logic problem are: (1) choosing some known part of the total information block for parallel review of the entire block and (2) parallel logic processing of a sequence of codes. The described device fulfills these essential components thereby improving information processing and increasing the speed of…

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 characteristics of the Intrex subject/title inverted file are analyzed. Basic statistics of the inverted file are presented including various distributions of the index words and terms from which the file was derived, and statistics on stems, the file growth process, and redundancy measurements. A study of stems both with extremely high and…

The third phase of a four-phase program developed by the Federal Library Committee Task Force on Library Automation in conjunction with its overall objective of reviewing and reporting upon the status of automation in Federal libraries is reported. The first phase of the overall program appraised the current activities in library automation and…

An automated SDI service based on tapes supplied by DDC, Science Abstracts, and Engineering Index is evaluated as a component element of the entire HDL information system. Current studies for improving the efficiency are briefly described,--in particular, the establishment of a parameter reference service that should shorten the lead-time for the…

Explains an experiment in text-searching retrieval for cancer questions which developed and used computer procedures (via human simulation) to select search words from medical dictionaries. This study is based on an earlier one in which search words were humanly selected, and the recall results of the two studies are compared. (Author/LRW)

The techniques of search strategy design for substructure searches of the Wiswesser Line Notation (WLN) file are described in detail. The Index Chemicus Registry System'' was used. (13 references) (Author/SM)

The set reduction algorithm is based on set theory and Boolean algebra rather than the graph-theoretic approach. Time trials with a small file of organic chemical structures indicate that the algorithm can be economically used for substructure (or complete structure) sequential searches on a file containing 30,000-50,000 computer-coded structures.…

The first part of the paper deals with statute law and describes the inadequacy of the official Statutes Revised' system for maintaining up-to-date records. There is a similar lack of official retrieval tools for tracing information on case law. The problems of factual information retrieval are dealt with briefly. (Author/NH)

The TSS (Topological Screens System) for substructure search was applied to the CAS Registry file making it searchable on-line. The TSS screens and the use of the screen indexes are described. Statistics on screen assignment are provided, and the strengths and weaknesses of the system are discussed. (Author/NH)

A brief look at the substantial body of computer, communication and microphotographic technologies which are available for aiding informational-retrieval processes in libraries. (NH)
