    Abstract
    Although relevance judgements are fundamental to the design and evaluation of all information retrieval systems, information scientists have not reached a consensus in defining the central concept of relevance. Re-examines the viewpoints of major writers in the field, then introduces a new approach. Considers that relevance is a multidimensional concept; that it is based on the human judgement process; that it is dependant on both internal (cognitive) and external (situational) factors; and that it is intersubjective but nevertheless systematic and measurable. Suggests a different paradigm from the classic source-to-destination communication model of information retrieval.

    Abstract
    Aims to determine the extent to which there is a core of relevance criteria that soans such factors as information need situations, user environments, and types of information. 2 recent empirical studies have identified and described user defined relevance criteria. Synthesizes the findings of the 2 studies as a 1st step toward identifying criteria that seem to span information environments and criteria that may be more situationally specific

    Abstract
    In studies of information users' cognitive behaviors, it is widely recognised that users' perceptions of their information problem situations play a major role. Time-line interviewing and inductive content analysis are 2 research methods that, used together, have proven extremely useful for exploring and describing users' perceptions in various situational contexts. This article describes advantages and disadvantages of the methods using examples from a study of users' criteria for evaluation in a multimedia context

    Abstract
    Part of a long term project which aims to develop a simple measurement scale based on user criteria, that will yield results applicable to the study of user evaluations in any type of information seeking and use environment. Describes 2 tests which were conducted to determine how users interpret criterion terms drawn from previous user based relevance studies. Presents results of these initial tests and describes conceptual and methodological challenges in long term development of the instrument

    Abstract
    Takes a cognitive approach toward understanding the behaviours of end users by focusing on the values or criteria they employ in making relevance judgements, or decisions about whether to obtain and use information. Compares and contrasts the results of 2 empirical studies in which criteria were elicited directly from individuals who were seeking information to resolve their own information problems. In 1 study, respondents were faculty and students in an academic environment examining print documents from traditional text-based information retrieval systems. In the other study, respondents were occupational users of weather-related information in a multimedia environment in which sources included interpersonal communication, mass media, weather instruments, and computerised weather systems. Provides evidence that a finite range of criteria exists and that these criteria are applied consistently across types of information users, problem situation, and source environments

    Abstract
    The criteria employed by end-users in making relevance judgments can be powerful and useful indicators of the values users ascribe to a variety of factors in their information seeking and use situations. This paper describes intermediate results in a long-term project intended to develop a measurement scale based on users' relevance criteria. The five tests that are reported here have involved 350 users in an effort to progressively refine and validate the scale content. The range of research questions and types of users and information environments have gradually been expanded to assess the adaptability and transferability of the instrument. The instrument provides quantitative data, notably criterion importance ratings that can be analyzed using several techniques. The substantive findings confirm those of previous studies on relevance evaluation behavior

    Abstract
    State of the art review of relevance as it relates to the behaviour of users seeking and using information rather than in evaluating the performance of information retrieval systems. Views relevance as a manifestation of human information behaviour and excludes works that view relevance only as matching or computational functions of information retrieval systems
