title = "Probabilistic aggregates",
abstract = "Though extensions of the relational model of data have beenproposed to handle probabilistic information, there has been no work todate on handling aggregate operators in such databases. In this paper, we show how classical aggregation operators (like COUNT, SUM, etc.)as well as other statistical operators (like weighted average, variance, etc.) can be defined as well as implemented over probabilistic databases. We define these operations, develop a formal linear program model for computing answers to such queries, and then develop a generic algorithm to compute aggregates.",
