With the increase in available educational data, it is expected that Learning Analytics will become a powerful means to inform and support learners, teachers and their institutions in better understanding and predicting personal learning needs and performance. However, the processes and requirements behind the beneficial application of Learning…

Describes the University of California at Berkeley's participation in the TREC (Text Retrieval Conference) interactive track experiments. Highlights include results of searches on two systems, Cheshire II and ZPRISE; system design goals and implementation; precision and recall results; search questions by topic and system; and results of…

A study of logical reasoning ability of endusers searching a CD-ROM index and its correlation to searching performance was conducted at the University of Illinois at Urbana-Champaign. Findings showed a correlation between cognitive skills and citation selection and indicated that computer system design can be improved using a cognitive engineering…

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…

This paper presents an information agent and latent semantic-based indexing architecture to retrieve documents on the Internet. The system optimizes the search for documents in the Internet by automatically retrieving relevant links. The information used for the search can be obtained, for instance, from Internet browser caches and from grades of…

Authority control improves users' access to a library's holdings by enhancing the ability to find and select materials. The AutoCat authority control system developed at Dickinson College (Carlisle, Pennsylvania) avoids the high initial costs of vendor clean up and Library of Congress authority tapes while reducing the labor involved in authority…

Discusses the concept of a digital library and the utility of space/time referencing. Describes the unified space/time/keyword/format search and retrieval and indexing system of the ISLA (Information System for Los Angeles) at the University of Southern California. Focuses on the practical application of space/time referencing and methods of…

Describes the use of the Z39.50 information retrieval protocol as the basis for Infocal, a read-only, client/server-based campus information system. Technical considerations in adapting the protocol to nonbibliographic data, including semantic modules, dynamic attribute sets, and dynamic record syntax, are described in detail. (Contains 11…

Describes the incorporation of textile images into the University of Maryland Historic Textile Database by a computer user rather than a computer expert. Selection of a database management system is discussed, and PICTUREPOWER, a system that integrates photographic quality images with text and numeric information in databases, is described. (three…

Reviews the characteristics of the Cheshire II system that is being used to implement full-text and fielded searching of bibliographic information for the University of California Berkeley Digital Library Initiative. Examines its performance when applied to a collection of large full-text documents in the TREC Interactive Retrieval Track and its…

A hypermedia based UTICS (university transaction, information and communication system) is under development at the University of Auckland (New Zealand). This multi-platform system will provide alternatives to traditional forms of information retrieval and dissemination as well as public relations exercises. The UTICS will offer a virtual journey…

This kit was developed to assist the postsecondary education community's efforts to resolve the Year 2000 (Y2K) computer problem. The kit includes a description of the Y2K problem, an assessment of the readiness of colleges and universities, a checklist for institutions, a Y2K communications strategy, articles on addressing the problem in academic…

Outlines the advantages of digital documents for scholars and offers considerations for designing systems for storing and retrieving digital information products. Discusses conventional and electronic storage and retrieval; network costs; digital storage; search strategies; acquisition prices; and digital initiatives. (AEF)

Discusses the application of theories of cognitive modeling to information systems design and describes research that investigated the validity of the repertory grid for incorporation into intelligent front-end interfaces for information storage and retrieval systems. Personal construct theory is discussed and future research is suggested. (67…

"Intermedia" is a hypermedia system which was developed for use in university research and teaching. It provides a framework for object-oriented, direct manipulation editors and applications, and the capability to link together materials created with those applications. Instructors are able to construct exploratory environments for their…
