Teague-Rector, Susan; Ghaphery, Jimmy – Journal of Web Librarianship, 2008
Academic libraries customize, support, and provide access to myriad information systems, each with complex graphical user interfaces. The number of possible information entry points on an academic library Web site is both daunting to the end-user and consistently challenging to library Web site designers. Faced with the challenges inherent in…

Bovey, J. D.; Brown, P. J. – Journal of Documentation, 1987
Describes software for displaying documents on computer graphics screens which provide the opportunity for interactive user interfaces. Based on a software system called Guide, this new approach relies on advances in hardware, such as the CD ROM, and can be used in the front end of a document retrieval system. (Author/LRW)

Foss, Carolyn L. – Information Processing and Management, 1989
Critiques existing approaches to computerized support for browsing and describes four new types of browsers that have been implemented in the Xerox NoteCards hypertext system. These browsers support the process of pursuing and returning from digressions and facilitate the integration of diverse sets of materials that have been browsed. (16…

Newby, Gregory B. – Proceedings of the ASIS Annual Meeting, 1992
Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…

Fan, David P.; And Others – Journal of the American Society for Information Science, 1992
Describes a unitized data system for a scientific database that stores descriptions of individual experimental steps as separate text-based subunits together with appropriate linking signals. Conversion of graphics into searchable text, use of natural language, and cost effectiveness are discussed. An example using a biology research paper is…

Hancock-Beaulieu, Micheline; And Others – Journal of Documentation, 1995
An online library catalog was used to evaluate an interactive query expansion facility based on relevance feedback for the Okapi, probabilistic, term weighting, retrieval system. A graphical user interface allowed searchers to select candidate terms extracted from relevant retrieved items to reformulate queries. Results suggested that the…

O'Kane, Kevin C. – Information Processing & Management, 1996
Describes an algorithm for computer generation of hierarchical indexes for document collections. The resulting index, when presented with a graphical interface, provides users with a view of a document collection that permits general browsing and informal search activities via an access method that requires no keyboard entry or prior knowledge of…

Burgess, Clifford; Swigger, Kathleen – Information Processing and Management, 1986
Describes the design of a database interface for infrequent users of computers which consists of a graphical display of a model of a database and a natural language query language. This interface was designed for and tested with physicians at the University of Texas Health Science Center in Dallas. (LRW)

Pejtersen, Annelise Mark – Electronic Library, 1992
Describes the Book House, an interactive, multimedia online public access catalog (OPAC) developed in Denmark that uses icons, text, and animation. An alternative design model that addresses problems in OPACs is described; and database design, system navigation, use for fiction retrieval, and evaluation are discussed. (20 references) (MES)

Kuzmich, Carl J.; And Others – 1993
The development of a HyperCard application program, "Connecting to Your MARS Account," is described. The program was intended to assist users of the biomedical computer system at the University of Pittsburgh (Pennsylvania), the Medical ARchival System (MARS), to connect to their computer accounts. Criteria from instructional, graphical,…
