Exploiting Captions in Retrieval of Multimedia Data.
Peer reviewed Peer reviewed
Rowe, Neil C.; Guglielmo, Eugene J. – Information Processing and Management, 1993
Discusses the use of natural language processing to help organize multimedia data. The MARIE system, which uses captions to embody the classificatory information and heuristic advice necessary to search a database of photographs, is explained. Advantages include improved speed of access and the ability for improved user interaction. (Contains 21…

Shifting the Information Paradigm from Data-Centered to User-Centered.
Peer reviewed Peer reviewed
Watters, Carolyn; Shepherd, Michael A. – Information Processing and Management, 1994
Discusses the shift of information access from a data-centered to a user-centered model and describes the Daltext system, a prototype user-centered information system that allows the user to determine how the data will be viewed (i.e., within a datastream model, a set model, a relational model, and/or a hierarchical model). (Contains 30…

Prototyping a Distributed Information Retrieval System That Uses Statistical Ranking.
Peer reviewed Peer reviewed
Harman, Donna; And Others – Information Processing and Management, 1991
Built using a distributed architecture, this prototype distributed information retrieval system uses statistical ranking techniques to provide better service to the end user. Distributed architecture was shown to be a feasible alternative to centralized or CD-ROM information retrieval, and user testing of the ranking methodology showed both…
