	abstract =	{The term relevance weighting method has been shown to
	produce optimal information retrieval queries under well-defined
	conditions. The parameters needed to generate the term relevance
	factors cannot unfortunately be estimated accurately in practice;
	futhermore, in realistic test situations, it appears difficult to
	obtain improved retrieval results using the term relevance weights over
	much simpler term weighting systems such as, for example, the inverse
	document frequency weights.It is shown in this study that the inverse
	document frequency weights and the term relevance weights are closely
	related over a wide range of the frequency spectrum. Methods are
	introduced for estimating the term relevance weights, and experimental
	results are given comparing the inverse document frequency with the
	estimated term relevance weights.},
