Presents an interaction model and an experimental method for information retrieval. This automated method helps identify which user and system variables are relevant, which are independent of other variables, and which ranges of the variables are most important. Results show that relevance feedback consistently improves retrieval performance. (AEF)

Presents a stratified model of information retrieval interaction that views interaction as a dialog between participants (user and computer) through an interface. Discusses traditional and interaction models, and extension to relevance, user modeling, search term selection, and types of feedback in information retrieval. (AEF)

Interactive systems must be designed to furnish error information to the user and must be able to accept a modification to the input and continue to cycle until convergence on the desired output is reached. (10 references) (Author)

Reports a preliminary investigation into the man-machine interaction aspects of online searching, including the methodology developed for observing and recording man-machine interface in the use of online information retrieval systems. Three references are cited, and a bibliography lists 16 sources. (FM)

The contradictory nature of the phrase user-oriented interface (UOI) as commonly applied to retrieval systems is discussed, and a different approach to the problem made feasible through improvements in the technology is described. (Author/JPF)

As an exploration of the frustration experienced by users of an on-line interactive retrieval system, students participated in an experiment using an experimental reference retrieval system for library literature. It was anticipated that significant variations in user behavior would be displayed by the control and experimental groups. (19…

Summarizing the methods currently being employed at the Ohio College Library Center (OCLC) for user interaction analysis, this study presents suggestions and provides examples for the use of audit trail data available from most online interactive systems. The sample data used in the analysis are from the OCLC online system used for cataloging,…

On the 14th and 15th of January, 1971, a workshop on The User Interface for Interactive Search of Bibliographic Data Bases was held in Palo Alto. The participants were provided in advance with a challenge paper and with a number of papers prepared in response to that challenge. The Workshop sessions themselves were devoted exclusively to focussed…

Describes an expert system which provides users who have information needs with terms to express search queries; introduces principles on which the system's behavior is based; describes the system's main procedures and decision rules; presents an example of system use; and outlines possible improvements in system search and evaluation procedures.…

A consideration of the development of on-line systems in terms of the computer changes that made on-line searching possible, and the use of these changes by information retrieval systems. (Author/KP)

Freedom from the necessity for technical understanding of online technology allows librarians to focus on the human factors in online interaction. This article discusses estimates of Web use, need for user assistance, alternative sources of information, information overload and relevance, Internet identities, pornography and library policy, and…

Compares the traditional model of the reference interview with a new model based on online information process. Findings offer new perspectives on the reference interview process and lend support to the adoption of a new reference model which shifts its venue from a person to person process, to one in which information itself provides the platform…

Discusses the CODER system, which was developed to investigate the application of artificial intelligence methods to increase the effectiveness of information retrieval systems, particularly those involving heterogeneous documents. Highlights include the use of PROLOG programing, blackboard-based designs, knowledge engineering, lexicological…

Lists and discusses factors affecting presearch interviews; common elements of the interview; and components of interviews with new or infrequent users, experienced users of search services, and on-site users. Do's and don'ts for library staff members during a search and skills and attributes for effective presearch interviews are also listed.…

Describes the mental coding processes involved in the flow of information when the user is interacting with an enabling information-retrieval (IR) system, or a system designed to stimulate the user's grasping towards a higher understanding of the information need/problem/task that brought the user to the system.
