    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.
