Abstract: A non-transitory, computer-readable medium includes instructions, that, when executed, cause processing circuitry to receive, from an electronic device, a request regarding a custom segment defined by a first Boolean expression of a plurality of segments having elements corresponding to, or representative of, one or more electronic devices and/or one or more users of the one or more electronic devices. The instructions, when executed, also cause the processing circuitry to generate a different, second Boolean expression based on the first Boolean expression and the plurality of segments. Additionally, the instructions, when executed, cause the processing circuitry to determine a number of distinct elements of the custom segment at least partially utilizing the second Boolean expression and a plurality of data structures corresponding to the plurality of segments.

Abstract: Systems and methods are provided for efficient computer-implemented forecasting of audience and/or audience demand for supplemental digital content. Specifically, an efficient target segment data structure is used with universe data to identify a viewership supply forecast. The forecast may be used to control downstream forecast dependent systems and/or services.
