    摘要: Techniques are provided for (1) extending SQL to support direct invocation of frequent itemset operations, (2) improving the performance of frequent itemset operations by clustering itemset combinations to more efficiently use previously produced results, and (3) making on-the-fly selection of the occurrence counting technique to use during each phase of a multiple phase frequent itemset operation. When directly invoked in an SQL statement, a frequent itemset operation may receive input from results of operations specified in the SQL statement, and provide its results directly to other operations specified in the SQL statement. By clustering itemset combinations, resources may be used more efficiently by retaining intermediate information as long as it is useful, and then discarding it to free up volatile memory. Dynamically selecting an occurrence counting technique allows a single frequent itemset operation to change the occurrence counting technique that it is using midstream, based on cost considerations and/or environmental conditions.

    摘要: A system may include a network interface and a batch processor coupled to the network interface. The batch processor may be configured to obtain social network profiles corresponding to entities and to obtain a target criterion. The batch processor may be configured to identify at least some of the entities based on a relationship between the social network profiles and the target criterion and to transmit, via the network interface, a data file to a computing device of the at least some of the entities, wherein the data file contains information related, at least in part, to the target criterion.
