- W2364454730 abstract "This paper studies diversity of information retrieval results.First,it implements the classic Maximal Marginal Relevance(MMR) algorithm to re-rank the initial retrieved results.Then it designs and implements three sub-topic construction methods based on query logs.Finally,it explores a method of combining the sub-topics with the Maximal Marginal Relevance algorithm to provide better diversified results.Experiments indicate these methods increase the diversity of the results significantly." @default.
