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.…

Intelligent Information Retrieval: Diagnosing Information Need. Part II. Uncertainty Expansion in a Prototype of a Diagnostic IR Tool.
Peer reviewed Peer reviewed
Cole, Charles; Cantero, Pablo; Sauve, Diane – Information Processing & Management, 1998
Outlines a prototype of an intelligent information-retrieval tool to facilitate information access for an undergraduate seeking information for a term paper. Topics include diagnosing the information need, Kuhlthau's information-search-process model, Shannon's mathematical theory of communication, and principles of uncertainty expansion and…

Name Collection by Ph.D. History Students: Inducing Expertise.
Peer reviewed Peer reviewed
Cole, Charles – Journal of the American Society for Information Science, 2000
Defines the task of the Ph.D. history student in terms of information needs; reports the results of a study of Ph.D. students that observed their accessing information based on collecting names; and theorizes that collecting names induced expert thinking by mimicking the mental representation of a history expert. (Contains 90 references.)…

Interaction with an Enabling Information Retrieval System: Modeling the User's Decoding and Encoding Operations.
Peer reviewed Peer reviewed
Cole, Charles – Journal of the American Society for Information Science, 2000
Discusses how to increase user satisfaction by designing information retrieval systems that inform the user while the user is interacting online. Models the information processing operations of a user who has received an information message from the system and is stimulated into grasping at a higher understanding of the information need. (Contains…

The Development of a Diagnostic-Prescriptive Tool for Undergraduates Seeking Information for a Social Science/Humanities Assignment. III. Enabling Devices.
Peer reviewed Peer reviewed
Cole, Charles; Cantero, Pablo; Ungar, Andras – Information Processing & Management, 2000
This article focuses on a study of undergraduates writing an essay for a remedial writing course that tested two devices, an uncertainty expansion device and an uncertainty reduction device. Highlights include Kuhlthau's information search process model, and enabling technology devices for the information needs of information retrieval system…

Visualizing a High Recall Search Strategy Output for Undergraduates in an Exploration Stage of Researching a Term Paper.
Peer reviewed Peer reviewed
Cole, Charles; Mandelblatt, Bertie; Stevenson, John – Information Processing & Management, 2002
Discusses high recall search strategies for undergraduates and how to overcome information overload that results. Highlights include word-based versus visual-based schemes; five summarization and visualization schemes for presenting information retrieval citation output; and results of a study that recommend visualization schemes geared toward…

The Optimization of Online Searches through the Labelling of a Dynamic, Situation-Dependent Information Need: The Reference Interview and Online Searching for Undergraduates Doing a Social-Science Assignment.
Peer reviewed Peer reviewed
Cole, Charles; And Others – Information Processing & Management, 1996
Proposes a reference-interview strategy that allows the reference librarian to assess the information need of the undergraduate doing social science research that requires the use of an electronic database; label the information need; and assign the most appropriate search strategy to satisfy this need. Questions for further study are offered.…
