    Abstract: The technology disclosed describes systems and methods for generating feature vectors from resource description framework (RDF) graphs. Machine learning tasks frequently operate on vectors of features. Available systems for parsing multiple documents often generate RDF graphs. Once a set of interesting features to be considered has been established, the disclosed technology describes systems and methods for generating feature vectors from the RDF graphs for the documents. In one example setting, a machine learning system can use generated feature vectors to determine how interesting a news article might be, or to learn information-of-interest about a specific subject reported in multiple articles. In another example setting, viable interview candidates for a particular job opening can be identified using feature vectors generated from a resume database, using the disclosed systems and methods for generating feature vectors from RDF graphs.

    Abstract: Methods, systems, and devices for data retention handling are described. In some data storage systems, data objects are stored in a non-relational database schema. The system may support configurable data retention policies for different tenants, users, or applications. For example, a data store may receive retention requests, where the retention requests may specify deletion or exportation actions to perform on records contained within data objects. The data store may determine retention rules based on these retention requests, and may periodically or aperiodically evaluate the rules to determine active actions to perform. To improve the efficiency of the system, the data store may aggregate the active actions (e.g., according to the dataset to perform the actions on), and may generate work items corresponding to the aggregate actions. A work processor may retrieve these work items and may efficiently perform the data retention actions on datasets stored in the data object store.

    Abstract: Disclosed are methods, apparatus, systems, and computer-readable storage media for generating or updating sets of events. In some implementations, a database storing data records representing events can be maintained. A selection of a first event can be processed. A first timestamp associated with the first event can be identified. A first set of events comprising the first event a first portion of other events can be generated or updated. A second set of events comprising the first event a second portion of other events can be generated or updated. A first frequency of matched events can be determined for the first set of events. A second frequency of matched events can be determined for the second set of events. It can be determined that the first frequency is greater than the second frequency. A similarity associated with the first event can be generated or updated. The first set of events can be provided to a client device.

    Abstract: Network traffic data associated with computer applications is collected based on static policies. First network parameter vectors are generated over a time period. Each network parameter vector of the first network parameter vectors comprises first optimal values, estimated by a Bayesian learning module using a generative model, for network parameters. Second network parameter vectors are generated over the same time period. Each network parameter vector of the second network parameter vectors comprises second optimal values, computed by a best parameter generator through optimizing an objective function, for the network parameters. It is determined whether the first network parameter vectors converge to the second network parameter vectors and whether network parameter optimization for the network parameters is performing normally.

    Abstract: Disclosed are examples of systems, apparatus, methods and computer program products for batch job processing using a database system. In some implementations, a data object relationship structure of a first record can be identified. Based on a type of data dependency of the data object relationship structure, a first record and a second record can be determined to be associated. A first batch number can be assigned to the first record and the second record. A first batch job can be defined. It can be determined that a third record is not associated with the first record. A second batch number can be assigned to the third record and a second batch job can be defined.

    Abstract: An attempt by a user to login to a destination server is identified from a source server. A destination score is determined based on the count of attempts by the user to login to the destination server and the count of attempts by the user to login to all destination servers. A source given destination score is determined based on the count of attempts by the user to login from the source server to the destination server, and the count of attempts by the user to login to the destination server. An outlier score is determined based on values associated with the destination score and the source given destination score. An alert is output if the outlier score satisfies a threshold.

    Abstract: Systems and methods for broadcasting events are provided. The system, for example, may include, but is not limited to, a communication system, a memory, and a processor. The processor may be configured to receive, from the communication system, a session identifier identifying a broadcast session and at least one application event corresponding to the broadcast session from a presenting electronic device, update a playback queue corresponding to the broadcast session stored in the memory based upon the received at least one application event, receive, from the communication system, a subscription request to the broadcast session from at least one subscribing electronic device, and transmit, via the communication system, a corresponding playback queue to each electronic device subscribed to the broadcast session, the playback queue including instructions to regenerate the application event within an application operating on the at least one subscribing electronic device.
