Assesses the retrieval effectiveness of automatically constructed interdocument hypertext links in information retrieval (IR). Describes experiments using statistical and probabilistic techniques that were designed to obtain evidence concerning the usefulness of querying and browsing automatically constructed IR hypertexts. Results indicate a…

Describes WebClass, a system that allows Web users to create personalized conceptual data that is dynamically merged with original HTML source by a proxy server. Explains the creation of alternative views of Web pages, data modeling, and navigation; and describes two possible applications of the system, annotation and indexing. (Author/LRW)

Considers the need for keyphrase-extraction techniques in intelligent Chinese information retrieval and presents a PAT-tree-based adaptive approach, developed from the PATRICIA Algorithm (Practical Algorithm to Retrieve Information Coded in Alphanumeric).

Reviews content-based image retrieval and discusses the increase in large picture databases that are now available. Describes some of the proceedings from the Brighton (United Kingdom) conference, including the retrieval of video clips; discusses image indexing; and provides examples of image indexing and retrieval projects. (Author/LRW)

Discusses latent semantic indexing (LSI); considers the high cost associated with the singular value decomposition (SVD) of the large term-by-document matrix that becomes a barrier for its application to scalable information retrieval; and shows that information filtering using level search techniques can reduce the SVD computation cost for LSI.…

Presents exploratory research evaluating a conceptual structure for the description of visual content of images. The structure classifies visual attributes into a "Pyramid" containing four syntactic levels and six semantic levels. Experiments performed suggest the Pyramid is conceptually robust and can be used to: organize visual content…

This article describes the development of the video bookmark, hereinafter referred to as the videomark, and its application to the collaborative indexing of the lecture video in video-based distance education system. The combination of the videomark system with the bulletin board system (BBS), which is another network tool used for discussion, is…

This article describes the survey of the usability of a novel content-based video retrieval system. This system combines video streaming and an electronic bulletin board system (BBS). Comments submitted to the BBS are used to index video data. Following the development of the prototype system an experimental survey with ten subjects was performed.…

Learning with existing web-based resources has become popular and important, for example, in cases where there are diverse learning resources dealing with the same learning topic. However, many resources do not have a clear description of their characteristics, which makes it difficult for learners to select appropriate resources. This article…

This Film News Index is an index to the 16mm nontheatrical film reviews and film history that were published in "Film News" over almost four decades, as well as an index to the location of the full reviews and articles in their original version. The Film News Index is composed of four sections: (1) Film Reviews, which provide film title,…

A new technique, known as discrimination value analysis, ranks the text words in accordance with how well they are able to discriminate the documents of a collection from each other. (Author/PF)

Outlines a procedure for cataloging and indexing pamphlets in historical collections. (PF)

This paper traces the development of classification at the Library of Congress in terms of its broader context and by accounting for changes in the present system since its initial period of creation between 1898 and 1910 and the present. Topics covered include: (1) Early Growth of the Collections; (2) Subject Access During the Early Years; (3) A.…

A comprehensive guide to the literature published between World War II and 1979 which critically evaluates the Library of Congress list of Subject Headings (LCSH), this bibliography has been prepared for information personnel involved with subject authority files, thesauri, or vocabulary control. A brief bibliometric analysis of the literature…

The first volume in a series of publications describing the basic documentation practices involved in the initial setting up and subsequent operation of an information-library organization to provide defense-aerospace scientific and technical information services, this manual consists of three sections. "Acquisition and Sources," by…
