Compares results of two empirical studies in which relevance criteria were elicited from individuals seeking information to resolve information problems. Results provide evidence that a finite range of criteria exists and that these criteria are applied consistently across types of information users, problem situations, and source environments.…

Proposes a cognitive approach to modeling users' perceptions in situations in which information content, information sources, and users themselves are constantly moving in time and space. A temporal-spatial model is explained and empirical support is provided by the results of a study of weather information users from a variety of occupations.…

Reports on an exploratory study that examined the criteria users mentioned in evaluating the results of their own multimedia searches related to weather information. Ten evaluation criteria are described, their relationships to information sources and presentation formats are examined, and directions for future research are suggested. (nine…

Discusses intermediate results in a long-term project intended to develop a measurement scale based on users' relevance criteria. Based on results of five tests involving 350 users, this paper describes the development process in terms of modifications to instrument content and design, variations of techniques for data collection and analysis,…

Arguing that relevance judgments are fundamental to the design and evaluation of all information retrieval systems, and that a consensus on the definition of the central concept of relevance has not been reached, this paper begins by critically reviewing four approaches to the problem of defining relevance: (1) the system-oriented approach…

Presents preliminary findings of a project intended to develop a user-validated measurement instrument based on users' relevance criteria. Two validation tests revealed conceptual and methodological challenges involving the semantic ambiguity of terms and verified the importance of situational context to scale development and use.

Considers the meaning of relevance and examines the role that relevance plays in information behavior. Literature on relevance is reviewed, cognitive and dynamic processing approaches to relevance are described, and 12 research questions are presented that address criteria users employ in evaluating information and suggest implications for system…
