This thesis work is mainly focused on two problems related to improving accessibility of information graphics for visually impaired users. The first problem is automated analysis of information graphics for information extraction and the second problem is multi-modal representations for accessibility. Information graphics are graphical…

The adaptability of the theory of integrative levels to a generalised classification scheme is questioned in that its hypotheses have not been adequately developed and confirmed. It is suggested that not enough cognisance has been taken of twentieth century relativistic thinking in which space-time is treated as a continuum. (14 references)…

Reviews the progress of parallel computing in information retrieval (IR) and stresses the importance of the motivation in using parallel computing for text retrieval. Analyzes parallel IR systems using a classification defined by Rasmussen; describes retrieval models used in parallel information processing; and suggests areas of needed research.…

Designed for use with a computer-produced subject index, PRECIS assigns clerical procedures in subject heading work to computer programs. The subject headings represent a unique combination of several different characteristics, permitting several coextensive forms of a subject name for each work. Final choice amongst alternatives is made by the…

Describes an alternative method for indexing images in an image database. The method consists of manually indexing a selected reference image, and then using retrieval by graphical content to automatically transfer the manually assigned index terms from the reference image to the images to be indexed.

This examination of abstracting-indexing services for the field of history focuses on Historical Abstracts (HA) and America--History and Life (AHL), and their relationship to the American Bibliographical Center's Subject Profile Index (ABC-SPIndex). The history, scope, selection criteria, and classification arrangements of the two databases are…

The report is concerned with the implementation of an on-line information storage and retrieval system for the Rome Air Development Center. This system is to incorporate techniques of automatic document classification for a large document collection in an interactive environment. Following a review of the system design, the implementation of the…

INTERACTIVE COMPUTER SYSTEMS ESTABLISH A DIALOG BETWEEN THE MAN AND THE MACHINE. BY MEANS OF DISPLAYS, THE USER RECEIVES IMMEDIATE FEEDBACK OF THE RESULT OF HIS ACTIONS, AND HE IS ABLE TO MODIFY HIS DECISIONS IN ORDER TO OBTAIN A SYSTEM RESPONSE THAT IS MOST RELEVANT TO HIS NEEDS. BOLD (BIBLIOGRAPHIC ON-LINE DISPLAY) IS AN EXAMPLE OF A HIGHLY…

Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document.

THE SECOND CUMULATIVE EDITION OF THE EDUCATIONAL RESOURCES INFORMATION CENTER/CLEARINGHOUSE ON THE RETRIEVAL OF INFORMATION AND EVALUATION IN READING (ERIC/CRIER) INFORMATIONAL PUBLICATIONS INCLUDES THREE NEWSLETTERS AND THREE INFORMATION BRIEFS. THE NEWSLETTERS PRESENT DISCUSSIONS OF THE ERIC/CRIER DOCUMENT PROCESSING FOR RESEARCH IN EDUCATION,…

The monograph presents a classification system of vocational rehabilitation program evaluation technology and literature intended to be useful for the efficient retrieval of program evaluation information and to provide greater communication among rehabilitation personnel. The classification system's purpose is to control the nuances of expression…

An introduction to the classification principles for documents at the Non-Formal Education Information Center is given for the cataloger. The classification scheme, itemized in the first section, consists of 11 main categories such as concepts, training methods, program content, bibliographies, and countries. The next section details…

An information retrieval system was developed using technical word occurrences as a basis for classification. A set of words, designated a vocabulary, was selected from the middle range of frequency listing of words occurring in an experimental sample of 94 documents. The selection produced 115 non-function words with technical definition that did…

A description is given of the RAIDS (Rapid Availability of Information and Data for Safety) method of information storage and retrieval. Acquired data are stored in the library in its original printed form. RAIDS provides three approaches to the identification and retrieval of data. The first approach is to organize the information into logical…

Specific aspects of the thesaurus treated in this brief review are: thesaurus as a concept, classification and structure, and language compilation and control. (75 references) (NH)
