Abstract

Develops a theoretical framework for expressing the nature of feedback as a critical process in interactive information retrieval. Feedback concepts from cybernetics and social sciences perspectives are used to develop a concept of information feedback applicable to information retrieval. Adapts models from human-computer interaction and interactive information retrieval as a framework for studying the manifestations of feedback in information retrieval. Presents results from an empirical study of real-life interactions between users, professional mediators and an information retrieval system computer. Presents data involving 885 feedback loops classified in 5 categories. Presents a connection between the theoretical framework and empirical observations and provides a number of pragmatic and research suggestions

Abstract

Information science is best defined as a discipline in terms of the problems it addresses. Its origins date back to the scientific and technical revolution after the 2nd World War, and its development has been essentially characterised by interdisciplinarity. Librarianship, computer science, cognitive science and communication studies all share interests with infomation science, but with increasing emphasis on the information society and the information industry dictated by technological imparatives, information science is now at a critical point in its evolution. The problem it sets out to solve are not decreasing but changing, with the pressure to improve access to an ever increasing store of knowledge. The social need for information science is evident, whatever the name given to the knowledge and skills which it encompasses

Abstract

Synthesises the major findings of several decades of research into the magnitude of individual deffirences in information retrieval related tasks and suggests implications for practice and design. The study is related to a series of studies of human aspects and cognitive decision making in information seeking, searching and retrieving

Abstract

Examines traditional and interactive models in information retrieval, and proposes an interactive information retrieval model based on different levels in the interactive process. Proposes a stratified interactive information retrieval model which has potential to account for a variety of aspects in the processes involved. In this model information retrieval interaction is decomposed into several levels that subtly affect each other. Makes general remarks on the state of information retrieval interaction research
