y join has attracted considerable attention. However, this operator does not consider the relationship among the elements in the answer, generating results with many pairs similar among themselves, which does not add value to the final answer. Result diversification methods are intended to retrieve

Given a group of query objects ., the goal of AggNN is to retrieve the . most similar objects from the database, where the underlying similarity measure is defined as an aggregation (usually .,

John Hagel III,Arthur G. Armstronged as a very efficient alternative for similarity retrieval. However, to the best of our knowledge, there are no previous works with experimental analysis on a comprehensive number of graph-based methods using the same search algorithm and execution environment. In this work, we survey the main grap

anisms use a “just-in-time” approach where distances are calculated as part of a navigational strategy. An alternative is to use a“one-time” approach, where distances to a fixed set of reference objects are calculated at the start of each query. These distances are typically used to re-cast data and
