Intelligent Information Retrieval: Diagnosing Information Need. Part I. The Theoretical Framework for Developing an Intelligent IR Tool.
Peer reviewed Peer reviewed
Cole, Charles – Information Processing & Management, 1998
Suggests that the principles underlying the procedure used by doctors to diagnose a patient's disease are useful in the design of intelligent information-retrieval systems because the task of the doctor is conceptually similar to the computer or human intermediary's task in information retrieval: to draw out the user's query/information need.…

eID: A System for Exploration of Image Databases.
Peer reviewed Peer reviewed
Stan, Daniela; Sethi, Ishwar K. – Information Processing & Management, 2003
Describes an exploration system for large image databases. The system, which consists of three stages, allows user to interpret and annotate an image in the context in which that image appears, dramatically reducing the time taken to annotate a large collection of images. Includes 25 figures and two tables. (AEF)

Massive Parallelism on the Hybrid Text-Retrieval Machine.
Peer reviewed Peer reviewed
Lee, Dik L. – Information Processing & Management, 1995
Provides an overview of HYTREM (Hybrid Text-Retrieval Machine), a high-performance, cost-effective text-retrieval machine that handles information in large textual databases. Describes HYTREM's software and hardware design principles and presents an evaluation of system performance in relation to user demand and access versus system capacity. (JMV)

Expert System Quality Control.
Peer reviewed Peer reviewed
Raggad, Bel Gacem – Information Processing & Management, 1996
A consultation quality control model (CQCM) developed for an expert system (ES) integrated both ES performance measures and end-user judgment values. Simple decision theory concepts were used to design the CQCM. Results show end users belong to different categories characterized by utility functions and the weights they assign to ES consultation…

Information Filtering via Hill Climbing, WordNet, and Index Patterns.
Peer reviewed Peer reviewed
Mock, Kenrick J.; Vemuri, V. Rao – Information Processing & Management, 1997
Discusses intelligent filtering systems and describes work in the INFOS (Intelligent News Filtering Organizational System) project designed to automatically categorize data as relevant or irrelevant based on user interests. The filtering is performed by combining keyword-based hill climbing, knowledge-based conceptual representation via WordNet,…
