【Abstract】 The paper discusses the dynamic process of retrieval decision and themode of feedback,pointing out that the process of setting-up search strate-gies is a kind of dynamic decision that can successively eliminate the fuzzi-ness and randomness of retrieval behavior through various ways of feedbackand adjustment.Finally,a tentative study ot the approaches and methods inadopting the retrieval dicision to dynamically optimize retrieval strategy ismade.更多还原
