Abstract
24 graduate students' relevance judgements were observed to find dimensions and characteristics of relevance. Findings were: that relevance is multidimensional; that there are 2 types of relevance dimensions, primary and secondary; that relevance dimensions show 3 orientations, problem, use, and value; and that the problem orientation is primary to the other orientations. The implications of these findings are that: 4 characteristics of important relevance dimensions were found; the important dimensions need to be applied to the system's measurement of relevance; relationships between thesaurus terms need to be set following the important dimensions; the important dimensions are useful for the effective evaluation of information retrieval; and that these and the orientations of relevance are useful to observe users' relevance judgements of the study of variables affecting relevance judgements
