- 845 abstract "When a user's underlying information need cannot be unambiguously determined from an initial query, an effective approach is to diversify the results retrieved for this query. In this paper, we introduce a novel probabilistic framework for search result diversification, which explicitly accounts for the various aspects associated to a query. In particular, we estimate how well a given document satisfies each uncovered aspect and how well different aspects are satisfied by the result ranking as a whole, so as to effectively and efficiently achieve the desired objective of diversification. We thoroughly evaluate our framework in the context of the diversity task of the TREC 2009 Web track. Moreover, we exploit query reformulations provided by three major Web search engines (WSEs) as a means to uncover different query aspects. The results attest the effectiveness of our framework when compared to state-of-the-art diversification approaches. Additionally, by simulating an upper-bound query suggestion mechanism from official TREC data, we draw insights regarding the effectiveness of the query reformulations generated by the different WSEs in promoting diversity.".
