In this paper considers the problem of determinizing probabilistic data to enable such data to be stored inlegacy systems that accept only deterministic input. Probabilistic data may be generated by automated dataanalysis/enrichment techniques such as entity resolution, information extraction, and speech processing. The legacysystem may correspond to pre-existing web applications such as Flickr, Picasa, etc. The goal is to generate adeterministic representation of probabilistic data that optimizes the quality of the end-application built on deterministicdata. We explore such a Determinization problem in the context of two different data processing tasks triggers andselection queries. We show that approaches such as thresholding or top-1 selection traditionally used forDeterminization lead to suboptimal performance for such applications. Instead, we develop a query-aware strategy andshow its advantages over existing solutions through a comprehensive empirical evaluation over real and syntheticdatasets.
