Improving Information Retrieval by Combining User Profile and Document Segmentation.
Peer reviewed Peer reviewed
Laine-Cruzel, S.; And Others – Information Processing & Management, 1996
Describes the design of an information retrieval system that permits the personalization of a search by developing a user profile in order to reduce noise and increase the number of relevant items retrieved. The preorientation system is explained and an example using full-text natural language processing tools is presented. (Author/LRW)

Multimedia Document Management: An Anthropocentric Approach.
Peer reviewed Peer reviewed
Bianchi, Nadia; And Others – Information Processing & Management, 1996
Describes the architecture of an anthropocentric Biomedical Information Management System prototype that is based on a network of computational components, or agents, that expert biomedical users can define, use, and refine to serve their own communication and documentation habits and needs. The innovation of the proposal, the Participatory Design…

A Straightforward NF Squared Relational Interface with Applications in Information Retrieval.
Peer reviewed Peer reviewed
Niemi, Timo; Jarvelin, Kalervo – Information Processing & Management, 1995
Discusses a user interface that simplifies NF Squared (non-first-normal-form) relational query formulation in which query specification remains compact and straightforward. This interface allows for nesting and general hierarchical structures and restructuring which provides for more effective retrieval and query formulation. (Author/JKP)

User Studies Informing E-Table Interfaces.
Peer reviewed Peer reviewed
Marchionini, Gary; Mu, Xiangming – Information Processing & Management, 2003
Describes a series of user studies used to advance understanding of how people use electronic tables (E-tables) and inform the development of a Web-based statistical table browser for use by non-specialists. Results of needs assessment, prototype development, and user studies provide a foundation for understanding E-tables in general and guiding…
