  • Patent number: 11422856
    Abstract: Techniques are disclosed relating to scheduling program tasks in a server computer system. An example server computer system is configured to maintain first and second sets of task queues that have different performance characteristics, and to collect performance metrics relating to processing of program tasks from the first and second sets of task queues. Based on the collected performance metrics, the server computer system is further configured to update a scheduling algorithm for assigning program tasks to queues in the first and second sets of task queues. In response to receiving a particular program task associated with a user transaction, the server computer system is also configured to select the first set of task queues for the particular program task, and to assign the particular program task in a particular task queue in the first set of task queues.

  • Patent number: 11354295
    Abstract: Methods and systems for processing incoming data in real-time are described herein. The incoming data is processed in real-time to generate data records that may be improved over time, for example, by automatically correcting inaccurate data in the records. In some embodiments, when data is received, a real-time process is initially performed on the received data under a first time constraint to produce first data for a data record. Subsequently, one or more non-real-time processes are then performed on the received data under a second time constraint to produce second data for the data record. The second data may be used to update the data record, for example, to correct any inaccuracy caused by the real-time process of the received data. Preferably, the second time constraint is longer than the first time constraint.

  • Patent number: 11162796
    Abstract: Methods and systems for assisting a user at an event and venue are described. A user is guided or navigated to different points of interest at a venue. The points of interest include seat locations or surrounding services and facilities, such as restaurants, shops, and restrooms. Advertisements and promotions associated with surrounding services may be displayed to the user. The user may be notified of the presence of friends and family at the same venue, and be provided with real-time information about the event.

  • Patent number: 10887729
    Abstract: A method is provided that includes accessing, by a server provider server of a service provider, a database storing associations between network addresses and locations. Additionally, the method includes determining a subset of the database corresponding to a first network address, each association included in the subset corresponding to an association between the first network address and a respective location. The method also includes in response to determining that the subset of the database satisfies one or more clustering criteria, calculating a representative location corresponding to the first network address, and storing an association between the first network address and the representative location in a second database.
