Abstract: This paper examines the problem of computing diverse query results which is useful for browsing search results in online shopping applications. The search results are diversified wrt a sequence of output attributes (termed d-order) where an attribute that appears earlier in the d-order has higher priority for diversification. We present a new indexing technique, D-Index, to efficiently compute diverse query results for queries with static or dynamic d-orders. Our performance evaluation demonstrates that our D-Index outperforms the state-of-the-art techniques developed for queries with static or dynamic d-orders.
