Retrieving files from one's computer is done daily and is an essential part of completing most tasks at work, yet surprisingly little research has examined the ways that people structure and organize their files. Management of personal digital information is a challenging task that users approach idiosyncratically. Large individual differences…

Extensions are required to the currently operational INGRES data base system for it to manage a data base distributed over multiple machines in a computer network running the UNIX operating system. Three possible user views include: (1) each relation in a unique machine, (2) a user interaction with the data base which can only span relations at a…

A record format and file structure for searching and editing of large textual files have been designed within the 3RIP project. This document describes: (1) general characteristics of the system; (2) implementation of the system on a DEC 10 computer in the programming language, BLISS; (3) external record format; (4) internal format; and (5) file…

The computer system described was developed as a departmental aid in locating documents for use as teaching material or for research purposes in the area of information science. The data base of about 2,000 records includes a departmental library of manuals, reports, technical literature, and reprints, as well as journal references and book…

The file design of the search system part of an interactive search and editing system, 3RIP, is described. A scatter-stored and compact inverted file is used to search a primary file of up to 4 million records containing on the order of 10-E9 characters of text and numeric data. Searchable attributes are keywords, words or phrases in text, names,…

The application of computer technology to storage and retrieval of geoscience data has increased markedly since about 1966, and has resulted in the publication of numerous papers describing various aspects of this work. Unfortunately, these are widely dispersed in the literature, many in relatively obscure journals, proceedings and other sources.…

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…

Retrospective search of large data bases requires development of special techniques for automatic compression of data and minimization of the number of input-output operations to the computer files. The computer program should require a relatively small amount of internal memory. This paper describes the structure of such a program. (9 references)…

Human individuals, social organizations and societies are alike in that their knowledge of past events is to some extent maintained and brought to bear on their behavior. On the individual level we know quite a bit of how this is accomplished. However, on the social level we know close to nothing. It is not the task of this paper to ascertain the…
