Abstract: Systems and methods for providing notification delivery based on utilization of bloom filters are provided. A collaboration system obtains subscriber information for each user of a collaboration system, whereby the subscriber information corresponds to one or more features of content that are relevant to each user. The collaboration system hashes the subscriber information to generate a bloom filter for each user. The collaboration system receives an article to be published, whereby the article comprises a set of features. The set of features is hashed to obtain a hash set. The hashing of the set of features is performed using same hashing functions as that used to generate the bloom filter. The collaboration system compares the hash set to the bloom filter to identify a match, whereby the match indicates a feature of the article matches the subscriber information. The collaboration system generates a list of recipients based on the match.

Abstract: A system may include a processor; and a memory storing instructions that, when executed by the processor, configure the processor to: receive, from a computing device, a request for a set of content, the request associated with a user identifier; query a cached data store to determine that a set of audiences for the user identifier is stale; in response to the determination that the set of audiences is stale: access user properties for the user identifier; and generate the set of audiences for the user identifier based on the user properties; and serve the set of content according to the generated set of audiences.
