Abstract: Systems and techniques for content creator messaging framework are described herein. Information that indicates member activities corresponding to a content item corresponding to a content segment may be obtained for a date range. A set of distinct members may be determined that are associated with the information that indicates member activities. Edges may be identified in a connections network between each member of the set of distinct members and the content creator. An edge weight may be calculated for each edge using a number of interactions between content items created by the content creator and the member. A content creator ranking may be generated for the content creator using the edge weight for each edge. A content creator notification may be transmitted to the content creator based on determining that the content creator ranking is outside a threshold.

Abstract: The present invention provides a re-partitioning-based sampling system and method which provides for generating a synopsis from large database tables such that an aggregation query performed on the synopsis provides an approximate answer to the aggregation query which is in prescribed error bounds relative to a query on the full database. The system includes a partition function generator, a synopsis vector calculator, and a synopsis constructor. The synopsis constructed by the system is sufficiently small to be held in memory to allow quick and resource efficient satisficing of aggregation queries.
