摘要：

Previous experiments demonstrated the value of relevance weighting for search terms, but relied on substantial relevance information for the terms. The present experiments were designed to study the effects of weights based on very limited relevance information, for example supplied by one or two relevant documents. The tests simulated iterative searching, as in an on-line system, and show that even very little relevance information can be of considerable value. © 1979, MCB UP Limited
