Engineering students used ClassTranscribe, an accessible video player, in multiple engineering courses to view course videos and search for video content. The tool collected detailed timestamped student behavioral data from 1,894 students across 25 engineering courses that included what individual students searched for and when. A previous…

It is critical that students learn how to retrieve useful information in hypermedia environments, a task that is often especially difficult when it comes to image retrieval, as little text feedback is given that allows them to reformulate keywords they need to use. This situation may make students feel disorientated while attempting image…

For the forty-third time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented online during the annual AECT Convention. Volume 1 contains 37 papers dealing primarily with research and development topics. Papers dealing with the…

Introduction: The purpose of this study is to compare characteristics and features of user supplied tags and search query terms for images on the "Flickr" Website in terms of categories of pictorial meanings and level of term specificity. Method: This study focuses on comparisons between tags and search queries using Shatford's categorization…

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…

This study investigates the relationships between the use of a zoom tool, the terms they supply to describe the image, and the type of image being viewed. Participants were assigned to two groups, one with access to the tool and one without, and were asked to supply terms to describe forty images, divided into four categories: landscape, portrait,…

The growing body of research investigating how people search for or locate information in a variety of materials is reviewed and extended. Although the nature of materials and the complexity of locating tasks varies in the seven articles, each aims to elucidate the conditions that affect search processes. (SLD)

Discusses methods of browsing in online public access catalogs (OPACs) and describes one method that uses information pertaining to the physical description of books from MARC records to simulate images of books on a library shelf. Electronic browsing through MARC is discussed, and methods of enhancing OPACs are reviewed. (51 references) (LRW)

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;…

Reports the preliminary findings of a research project that investigated users' mental models in the course of an image search. Generalist users searched a database of 1500 earth and space science images using a system that provided for both textual and content-based retrieval modalities. Factors such as ease of use and satisfaction with the…

Briefly discusses Web mining and image retrieval techniques, and then presents a summary of articles in this special issue. Articles focus on Web content mining, artificial neural networks as tools for image retrieval, content-based image retrieval systems, and personalizing the Web browsing experience using media agents.

Computer vision offers a variety of techniques for searching for pictures in large collections of images. Appearance methods compare images based on the overall content of the image using certain criteria. Finding methods concentrate on matching subparts of images, defined in a variety of ways, in hope of finding particular objects. These ideas…

A meta-analysis procedure was used to review research on pictorial effectiveness which focused on the use of static iconic visuals in instructional materials. The purpose of this exploratory study was to provide a means for forming future hypotheses based upon a quantitative aggregation of past research. The study was concerned with differential…

Organized from the viewpoint of information retrieval theory, this review addresses issues of chemical information representation, comparison and matching, and retrieval strategies. Additional topics include similarity and clustering, visualization, and molecular diversity. Trends in research and application are identified, and gaps in the…
