Uses Kintsch's proposition-based construction-integration theory of discourse comprehension to detail the user coding operations that occur in each of the three subsystems (Perception, Comprehension, Application) in which users process an information retrieval systems (IRS) message. Describes an IRS device made up of two separate parts that enable…

Presents an overview of feedback within the cybernetics and social frameworks. These feedback concepts are then compared with the interactive feedback concept evolving within the framework of information seeking and retrieving, based on their conceptualization of the feedback loop and notion of information.

This paper demonstrates an approach which enables one to reduce in a systematic way the immense complexity of a large body of knowledge. This approach provides considerable insight into what is known and unknown in a given academic field by systematically and pragmatically ordering the information. As a case study, the authors selected…

A RETRIEVAL MODEL WAS DEVELOPED FOR TEACHING AND RESEARCH PURPOSES ON THE BASIS OF VARIED WORK EXPERIENCE AND ANALYSIS OF TECHNICAL DOCUMENT RETRIEVAL AND LIBRARY SERVICES. THE MODEL IS BASED ON SHANNON'S COMMUNICATION MODEL BUT IDENTIFIES THE WOULD BE READER, OR DESTINATION OF RECORDED MESSAGES, AS THE ACTIVATOR OF RETRIEVAL SERVICES. TWO MAIN…

Reviews and discusses critically the development during the last decade of the cognitive approach to information retrieval research and theory. The focus is analytic and empirical research on the complex nature of information need formation and situation, their inherent association with the concept of relevance, and the development of cognitive…

Processing complex multivariate information effectively when relational properties of information sub-groups are ambiguous is difficult for man and man-machine systems. However, the information processing task is made easier through code study, cybernetic planning, and accurate display mechanisms. An exploratory laboratory study designed for the…

The twenty-second in a series, this report describes research in information organization and retrieval conducted by the Department of Computer Science at Cornell University. The report covers work carried out during the period summer 1972 through summer 1974 and is divided into four parts: indexing theory, automatic content analysis, feedback…

Following an introduction providing background on the role of information, modern methods of information transfer and the theoretical bases of information systems are described. A second section deals with practical aspects of information services practices and operational management problems. A final section examines the specialized character of…

With the stated purpose of describing and appraising information science developments and trends during the past year, the 1975 Annual Review provides articles in the areas of planning, techniques and tools, and applications. National planning is reviewed for selected countries, and planning, development, and testing of new information systems are…
