This dissertation explores the use of geometric and graphical models for a variety of information search and filtering applications. These models serve to provide an intuitive understanding of the problem domains and as well as computational efficiencies to our solution approaches. We begin by considering a search and rescue scenario where both…

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…

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)

Describes the simulation of a nearest neighbor searching algorithm for document retrieval using a pool of microprocessors. Three techniques are described which allow parallel searching of a binary search tree as well as a PASCAL-based system, PASSIM, which can simulate these techniques. Fifty-six references are provided. (Author/LRW)

Describes a model for the workload of a full text retrieval system and of a simulation model for a version of an existing system called Full/Text. The effectiveness of various data caching strategies using the 2 models are explored, and the impact of various parameters on the strategies are evaluated. (13 references) (LRW)

Describes a microcomputer-based software package, Online Search Tutor (OST), which is designed to teach users online bibliographic searching. Modeled on software previously developed for the European Space Agency Information Retrieval Services (ESA-IRS), OST includes a database of 600 bibliographic records which will simulate actual search…

Discusses the evaluation of search engines and uses neural networks in stochastic simulation of the number of rejected Web pages per search query. Topics include the iterative radial basis functions (RBF) neural network; precision; response time; coverage; Boolean logic; regression models; crawling algorithms; and implications for search engine…

Describes the InfoMagic program at Chapman University (Orange, California), a three-part multimedia program for teaching information-access skills. Discusses the network simulations; automatic tracking and reporting; distributed versus centralized reporting; and student participation and feedback. Sidebars show examples of two student reports and…
