Intrex is an experimental bibliographic and full text storage and retrieval system which has advanced the concept of the on-line interactive search of a computer stored bibliographic data base and the on-line access to a microfiche document storage. The Intrex system includes a set of computer programs designed for information retrieval, a…

The Third Cranfield Conference on Mechanised Information Storage and Retrieval Systems was held on 20-23 July 1971 in Cranfield, England. The report describes a number of the key papers presented at this conference. (Author)

A model of a generalized information storage and retrieval system is proposed. The model consists of six subsystems (or blocks): logical processor, selector, descriptor, file, locator, document file, and analysis block. These subsystems function in a partial environment defined by the user and data blocks. Proceeding from a verbal description, a…

A retrieval system is considered in which document descriptions are stored and accessed in groups called clusters. All items in a cluster meet common similarity criteria and are represented by a composite entity called a profile. In large collections, profiles themselves are clustered and additional levels of profiles are generated. This entire…

This article describes the background, purpose, and organization of the ERIC Clearinghouse in Career Education, an information processing center. (KP)

This brief article concerning the development of the network of educational documentation centres in Arab countries is followed by a list which includes addresses of the centres. (SM)

A uniterm keyword system is explained which is thought to be suitable for small information centers operated by a staff of one or two. (3 references) (Author)

The Information Flow System is a large-scale information retrieval system developed for processing of Du Pont information files. As currently implemented, the system stores and retrieves information on company technical reports. Extensions of the system for handling chemical structure information and on-line processing are also discussed. (3…

Advantages of the Berkeley Mass Storage System (MSS) for information retrieval other than its size are: high serial-read rate, archival data storage; and random-access capability. By use of this device, the search cost in an SDI system based on the Nuclear Science Abstracts" data base was reduced by 20 percent. (6 references) (Author/NH)

This discussion of the general principles of structure and construction of numeric databases introduces the concept of data points, their relationship to each other, and their storage in a nonredundant way. The collection of numeric data and their integration into the database structure are explained. Eight references are cited. (EJS)

Describes an extensible object-oriented view system that supports the integration of both structured and unstructured data sources in either the multidatabase or data warehouse environment. Discusses related work and data mining issues. (AEF)

The technical report or "fugitive" literature collected by ERIC is produced using a wide variety of printing techniques, many formats, and variable degrees of quality control. Since the documents processed by ERIC go on to be microfilmed and reproduced in microfiche and paper copy for sale to users, it is essential that the ERIC document…

THE CENTER WAS ESTABLISHED TO COLLECT, ABSTRACT, SYNTHESIZE, PRODUCE, STORE, AND DISSEMINATE CAREER INFORMATION TO HIGH SCHOOLS AND JUNIOR COLLEGES IN SAN DIEGO COUNTY, CALIFORNIA. A STUDY WAS MADE TO DETERMINE THE TYPE OF CAREER INFORMATION DESIRED BY STUDENTS AND COUNSELORS. THE INFORMATION WAS PUT ON MICROFILM APERTURE CARDS. EACH CARD CONTAINS…

IBM's Administrative Terminal System (ATS) is an effective data collection device, but its searching capabilities are severely limited. Searching an ATS document line-by-line is a time consuming process requiring slow printout speeds. A search can operate only upon 9,999 lines of text at any one time. Working storage limitations make it necessary…

UNISTAR (User Network for Information Storage, Transfer, Acquisition and Retrieval) represents a management system for scientific and technological information under the executive branch of the United States Government and a training exercise in the systems approach. A summary of the salient points of this study indicates that: a national policy…
