Describes a study at Louisiana State University that described the criteria mentioned by users evaluating the information within documents as it related to the user's information need situation. Implications for understanding the concept of relevance, for the design and evaluation of information retrieval systems, and for future research are…

A computer system, IconiCase, is currently being developed to assist users in the task of classifying and memorizing medical cases. The system uses assemblies of icons, called Concept Graphics (CG), as pointers to medical cases, leading to a form of electronic document delivery in which information is accessed at various levels, with a gradual…

This paper describes a college math and computer science educator's experience integrating multimedia materials in classroom instruction. It serves as a "tutorial" for non-computer science educators considering adding multimedia presentations to their instruction. The paper covers: the time commitment for developing and integrating multimedia…

Information retrieval on the World Wide Web has a major obstacle: although data is abundant, it is unlabeled and randomly indexed. This paper discusses the implementation of a consultative Web search engine that minimizes the expertise level that is required from a user to accomplish an advanced search session. The system takes advantage of the…

Discusses instructional systems and information retrieval systems and highlights the growing role of retrieval systems in learning. Topics discussed include cognitive psychology; degree of learner control; interaction with the systems; technological trends, including storage capacity, integrated media, and interlinked systems; hypermedia; and…

Developed for the freshman writing program at University of Southern California (USC), Project Jefferson has two goals: to develop a model of computer-based instruction that includes the use of research tools and an interface that can be used with courseware in other disciplines; and to develop a researcher's notebook that permits easy access to…

Presents an Intelligent Negotiating Neural Network Design Model for solving the problem of poor information retrieval in subject searches of online catalogs. The purpose of the network, its architecture, and three different sessions of the user interface are described. Nineteen figures showing screens of the three sessions are appended. (Contains…

Describes a prototype information access system developed by NASA (National Aeronautics and Space Administration) called NAM (NASA Access Mechanism) to access the Internet for research and development activities. Topics addressed include the Science and Technical Information Program, information needs, networking requirements, functional and…

With vigorous development of the Internet, e-learning system has become more and more popular. Sharable Content Object Reference Model (SCORM) 2004 provides the Sequencing and Navigation (SN) Specification to define the course sequencing behavior, control the sequencing, selecting and delivering of course, and organize the content into a…

This manual is designed to supply background information for Kellogg Library and Archive Retrieval System (KLARS) processors and others who might work with the system, outline detailed policies and procedures for processors who prepare and enter data into the adult education database on KLARS, and inform general readers about the system. KLARS is…

Examines how informetric characteristics of information retrieval (IR) system databases can be used to help system designers decide what type of file structures would provide the best performance. The development of appropriate models describing database contents is highlighted in this first part of a two-part study. (30 references) (LRW)

This article reports the results of a study of Master's degree students concerning the role of individual differences in Internet searching, including cognitive styles, levels of prior experience, Internet perceptions, study approaches, age, and gender. Discusses retrieval effectiveness and self-efficacy and suggests implications for system…

This paper reports recent work in developing of structures and processes that support university teachers and instructional designers incorporating learning objects into higher education focused learning designs. The aim of the project is to develop a framework to guide the design and implementation of high quality learning experiences. This…

Learning Objects Metadata (LOM) aims at describing educational resources in order to allow better reusability and retrieval. In this article we show how additional inference rules allows us to derive additional metadata from existing ones. Additionally, using these rules as integrity constraints helps us to define the constraints on LOM elements,…

As learners use World Wide Web-based distance learning systems over a period of years, large amounts of learning logs are generated. An instructor needs analysis tools to manage the logs and discover unusual patterns within them to improve instruction. However, logs of a Web server cannot serve as learners' portfolios to satisfy the requirements…
