Abstract: The present disclosure relates to systems and methods for automatically associating additional content with sports games. The systems and methods obtain game schedule data for a plurality of sports games, and for each scheduled game, the systems and methods select articles published within a timeframe of the game date of the scheduled game. The systems and methods identify sports articles associated with the sports game based on entities and event phrases extracted from the sports articles matching the schedule game data. The systems and methods classify the sports articles into a plurality of clusters and use the clusters to associate the sports articles to the game schedule data and store the associated sports articles with the game schedule data.

Abstract: Disclosed herein is a method for facilitating determination of differences between a pair of regulatory documents. Accordingly, the method may include receiving a first regulatory document and a second regulatory document from a device, converting the first regulatory document and the second regulatory document from a source format to a preferred format, analyzing the first regulatory document and the second regulatory document of the preferred format, identifying first portions of the first regulatory document and second portions of the second regulatory document, classifying the first portions into first classification codes and the second portions into second classification codes, comparing the first classification codes with the second classification codes, determining a change associated with a first portion of the first portions, associating the change to the first portion, generating a combined annotated regulatory document, and transmitting the combined annotated regulatory document to the device.

Abstract: A database management system identifies a required column which is required for executing the query, reads out data of the identified required column from a storage device, and executes the query based on the data of the required column. When reading out the data of the required column, the database management system preferentially reads out the data of the required column from a high-speed storage device storing the data of the required column among a memory, a second storage, and a first storage, stores, in the memory, data of the second data size unit including the data of the required column used for executing the query, and, when the data of the required column is read out from the first storage, stores the data of the second data size unit in the memory and stores the read-out data of the first data size unit in the second storage.

Abstract: Disclosed herein is a method for facilitating classification of portions of a regulatory document using multiple classification codes.

Abstract: A system and method for providing fine-grained access control in a search engine. Access control predicates associated with a search query, including fixed-width and/or variable-width tokens, are received from the search engine, and are formatted in a machine-readable binary format to generate a single byte array. A pre-sorted memory index structure associated with the single byte array is generated, by sorting the access control predicates according to their token width. The pre-sorted memory index structure is merge joined with an uninverted terms index that includes a sorted list of all terms in a field associated with the search query, and a document index mapping the document identifier (ID) to a term ordinal for a specific field.

Abstract: Methods and apparatus to estimate audience sizes using deduplication based on binomial sketch data are disclosed. An apparatus includes processor circuitry to instantiate coefficient analyzer circuitry to determine coefficient values of a polynomial based on (i) variances in values in the first sketch data and second sketch data, (ii) a first cardinality of the first sketch data, and (iii) a second cardinality of the second sketch data. The processor circuitry to instantiate overlap analyzer circuitry to determine a real root of the polynomial, the real root corresponding to the quantity of the second subscribers that are duplicates of the first subscribers. The processor circuitry to instantiate report generator circuitry to estimate a deduplicated audience size based on the estimate of the quantity of the second subscribers that are duplicates of the first subscribers and the first and second cardinalities.

Abstract: One example method includes creating a namespace of a deduplication filesystem, adding a ‘temporary’ flag to the namespace, adding a ‘delete’ flag to the namespace when the namespace is to be deleted, and when a maximum number of namespaces permitted by the deduplication filesystem has been reached due to the creating of the namespace, deleting another namespace bearing a ‘temporary’ flag and a ‘delete’ flag. In this way, efficient use may be made of the NVRAM, while also maintaining compliance with deduplication filesystem requirements concerning the maximum number of permitted namespaces.

Abstract: A system and method is provided for selecting a backup plan based on sampled metadata. An exemplary method includes sampling metadata of files on a computer during a predetermined time interval, wherein the files are backed up to a storage server in accordance with a first backup plan. The method includes predicting file usage dynamics for a time interval subsequent to the predetermined time interval, based on a combination of the derivative features and the attributes of the metadata, and comparing the predicted file usage dynamics for the time interval with file usage dynamics of the predetermined time interval. In response to determining that a difference between the predicted file usage dynamics and the file usage dynamics of the predetermined time interval exceeds a threshold difference, the method includes selecting a second backup plan for the files, and backing up the files to the storage server accordingly.

Abstract: The disclosed systems and methods may receive a data record from either a legacy data source or a modern data source and determine whether the record satisfies a first set of validation rules. When the record fails to satisfy the first set of rules, reject the record for storage in a data store. When the record satisfies the first set of rules, determine whether the record satisfies a second set of validation rules. When the record satisfies the second set of rules, store the record in the data store with an indicator that the record satisfies the all rules. When the record fails to satisfy the second set of rules, if the source was a modern data source reject the record, and if the source was a legacy data source store the record in the data store with an indicator that it fails to satisfy the second set of rules.
