an iterative implicit feedback

... re-ranking method alone cannot solve the “relevant docu- ments sparseness” problem. Thus, the query ex- pansion method, which can provide fresh and relevant documents, can help the re-ranking ... significantly outperforms Google in these meas- urements, however, with query expansion, PAIR can perform even better. Thus, we say that result re-ranking and query expansion both play an important ... ex- pansion, and use Rocchio formulation (J. J. Rocchio, 1971) to re-rank the search results. Thus, their query expansion and re-ranking are computed separately and are not so concise and collaborative....
