Information filtering and information retrieval: two sides of the same coin?
TLDR
Models of information retrieval and filtering, and lessons for filtering from retrieval research are presented; users see only the data that is extracted. Expand
Ask for Information Retrieval: Part I. Background and Theory
TLDR
The results of the design study indicate that at least some of the premises of the project are reasonable, and that an ASK‐based information retrieval system is at least feasible. Expand
A faceted approach to conceptualizing tasks in information seeking
TLDR
A faceted classification of task is established which could be used to describe users' work tasks and information search tasks and provides a framework to further explore the relationships among work tasks, search tasks, and interactive information retrieval and advance adaptive IR systems design.

Information Concepts for Information Science
  • N. Belkin
  • Sociology, Computer Science
  • J. Documentation
  • 1978
TLDR
This review surveys contributions to the question of a suitable concept of information for information science, a problem within the theoretical structure of information science which must be solved in order for substantial progress in solving its practical problems to be made. Expand
Cognitive models and information transfer
TLDR
The intermediary's role in building up its own model of the user in interaction with the user is concerned, in order both to help theuser in clarifying the problem and to develop a representation of that problem which it judges likely to obtain useful responses from the knowledge resource. Expand
Ask for Information Retrieval: Part II. Results of a Design Study
TLDR
The theory and background to a design study for an information retrieval (IR) system based on the attempt to represent the anomalous states of knowledge (ASKs) underlying information needs and the methods and results are discussed. Expand
Braque: Design of an Interface to Support User Interaction in Information Retrieval
We suggest that information retrieval is most appropriately considered as an inherently interactive process, and describe the design of an interface to a bibliographic information retrieval systemExpand
The cognitive viewpoint in information science
  • N. Belkin
  • Computer Science
  • J. Inf. Sci.
  • 1 February 1990
TLDR
It is shown that considering problems of information science from this point of view has led to significant advances in a variety of areas of informationScience, including bibliometrics, user studies, the reference interview and information retrieval, which suggests that the cognitive viewpoint may be a powerful framework for the general theoretical and practical development of Information science.

Cases, scripts, and information-seeking strategies: On the design of interactive information retrieval systems
TLDR
This paper proposes a model of information retrieval system design based on the ideas of a multidimensional space of information-seeking strategies; dialogue structures for information seeking; cases of specific information- seeking dialogues; anti, scripts as distinguished prototypical cases; and demonstrates the use of the MERIT system, a prototype information retrieved system that incorporates these design principles. Expand
Display time as implicit feedback: understanding task effects
TLDR
Results of an intensive naturalistic study of the online information-seeking behaviors of seven subjects during a fourteen-week period demonstrate no general, direct relationship between display time and usefulness, and that display times differ significantly according to specific task, and according to Specific user.
