Abstract: A method, device and computer readable storage medium for reach deduplication across contents is provided. In the method, a plurality of non-overlapping object subsets is determined from an object set based on a plurality of object ranges. An object range is associated with at least one object attribute and targeted by a content of a plurality of contents that targets the object set. A reference number of objects targeted by at least one content in each object subset is determined based on a plurality of individual correlation metrics. An individual correlation metric corresponds to a content and indicates a degree of correlation between objects in the object subset and the content. A target number of objects targeted by the plurality of contents in the object set is determined based on the respective reference numbers in the plurality of object subsets.
