Information systems increasingly provide options for visually inspecting data during the process of information discovery and exploration. Little research has dealt so far with user interactions with these systems, and specifically with the effects of characteristics of the displayed data and the user on performance with such systems. The study…

Briefly surveys the numerous applications of fuzzy set theory on data representation and information retrieval. The importance of fuzzy set theory with respect to information systems is illustrated with a bibliography of 86 papers that describe data systems that are somehow "fuzzy." (Author/EM)

Text analytics refers to the process of analyzing unstructured data from documented sources, including open-ended surveys, blogs, and other types of web dialog. Text analytics has enveloped the concept of text mining, an analysis approach influenced heavily from data mining. While text mining has been covered extensively in various computer…

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…

Describes the data bases and programs of numerous on-line retrieval systems for chemical information, including mass spectra, NMR, x-ray, and substructure data. (MLH)

With many information retrieval (IR) schemes available, researchers have begun to investigate the benefits of combining results of different IR schemes to improve performance, in the process called "data fusion." This article investigates the predictive power of two variables--similarity of efficacy and dissimilarity of outputs--in simple…

Overview of issues concerning computer-monitored data for research in communication and information science includes a description of systems and kinds of data possible; uses of data; advantages of and problems with computer-monitored data and collection; prior research using computer-monitored data; prospects for future research. A 111-item…

Examines the structure and components of information storage and retrieval systems and information filtering systems. Identifies 13 components as representations of data objects (copies, excerpts, descriptions, abstractions, and identifying references) and functions that operate on them. Reduces the functional components to transformation and…

The nature of typical mechanized data bases with which university information centers and libraries will be working is examined to provide background information for data base retrieval efforts. Format and content of the data must be taken into consideration before meaningful retrieval can be achieved. Hence both of these aspects are treated in…

Recent technological advances in computers and communications make possible the integration of data systems and the exchange of data among them on an expanding scale. However, the full effect of these advances cannot be realized unless the need for uniform understanding of the common information (data elements) and its expression in data systems…

During the 1971-72 pilot test of the Southwest Regional Laboratory's (SWRL) Instructional Management System (IMS), three alternative procedures were used to gather data within the classroom, transmit those data to SWRL for processing, and send IMS output to the appropriate recipients in the schools. ComSys 3--one of the three…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…
