To quickly assess the difficulty of the text, read a short excerpt:
Relevance in this view is roughly the probability of satisfjdng an inforraation need. Cooper (1969) describes a precise definition of relevance based on his logical consequence detecting question answering sj'^stem (I96I1) 5 that is, that a stored statement is relevant to a query if and only if it is a member of a minimal premise set of which the query is a logical consequence for either the query or its negation. This is a mathematically precise de- finition only for certain inferential data r...etrieval systems, but can be conceptually extended to reference retrieval systems: "A docuraent is relevant to an information need if and only if it contains at least one sentence wliich is relevant to that need." (Cooper, I969, p. 10). Cooper concludes by contrasting utility and relevance in measuring the performance of retrieval systems and states that perhaps the relevance of "relevance" is that it is the most important factor in utility (1969, pp. 21-22). An important factor in the utility of a specific document to a specific request might be its dependency on previously read documents!
