This dissertation focuses on investigating whether users will locate desired images more efficiently and effectively when they are provided with information descriptors from both experts and the general public. This study develops a way to support image finding through a human-computer interface by providing subject headings and social tags about…

This thesis describes work done as part of the Video Console Indexing Project (VICI), a program to improve the quality and reduce the time and work involved in indexing documents. The objective of the work described was to design a video terminal system which could be connected to a main computer to provide rapid natural communication between the…

Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic…

Project Intrex is a program of experiments intended to provide a foundation for the design of future information transfer systems, with the library of the future visualized as a computer-managed communications network. In order to discover the necessary facts, especially in the area of the user's interaction with the system, experimentation is…

Suggests the designation of overlapping hierarchies in thesauri, first outlined in 1973, as a key element in progress towards a successful man-machine partnership. Article updates, expands, and provides theoretical background of 1973 proposal; postulates use of the UDC; and suggests means of distinguishing overlapping terms from other…

Discusses SOUCIT, a suite of programs designed by the Computer Unit of Robert Gordon's Institute of Technology in association with the Scottish Education Department Qualified Indexing Project to create a database of references to educational technological literature and link them in a meaningful way through qualified citation. The structure of the…

NETPAD is a microcomputer-based system, implemented on a Commodore PET 2001-8, by which a human indexer can input, retrieve, and edit information in order to produce a variety of permuted index displays. The basic unit of the NETPAD system is a subnetwork (a description of a single document) containing a set of concept nodes (author, title, date,…

This report describes the current status of Project INTREX experiments and provides a detailed technical record. Activities concentrating on the bibliographic access problem involve: (1) the investigation of a digitally-encoded, machine-manipulated augmented catalog, for which the task of preparing entries for 10,000 documents is about half…

This annual update of a bibliography that was published as a supplement to the first issue of "Online Review" contains 931 references covering the approximate time period of late 1982 through early 1984. Entries are arranged by author within each of 11 sections. Permuted title and author indexes are included. (EJS)

Provides permuted title and author indexes to the 931-item seventh annual update (July 1984 issue of "Online Review") of a bibliography on online information retrieval which was published as a supplement to the first issue of "Online Review." The approximate time period of late 1982 through early 1984 is covered. (EJS)

Synthesizes major findings from research on the magnitude of individual differences in information retrieval (IR) tasks and suggests implications for practice and design of IR systems and interfaces. Topics discussed include indexing consistency, relevance judgments, selection of subject headings, selection of search terms, and search retrievals.…

This essay focuses on use of the Library of Congress Subject Headings system in online catalogs for the retrieval of information by subject. Among the topics addressed are differences among catalog forms (card, microform, and computer); user interface with different forms of catalog; the types of subject indexes employed in present online…
