Traces the development of "The Thesaurus of Psychological Index Terms" from its roots as a term list through six editions to a sophisticated searching and indexing tool, and describes the process for determining controlled vocabulary and forms of display. Features designed especially to assist novice users and nonpsychologists are also…

Discusses how to make better indexes for online documentation. (SR)

Provides an overview of indexing in database management systems to provide librarians with more understanding of the possibilities and limitations of current information systems. Sequential, direct, indexed sequential, and virtual sequential file accessing methods are explained, and various binary tree structures are described. (EAM)

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). Discusses Internet utilization, automatic term suggestion, domain-specific lexicon…

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…

The issue of structural and semantic interoperability among learning objects and other resources on the Internet is increasingly pointing towards Semantic Web technologies in general and ontology in particular as a solution provider. Ontology defines an explicit formal specification of domains to learning objects. However, the effectiveness to…

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)
