  • Behavior modeling based on content genre
    Patent number: 11849180
    Abstract: Disclosed are systems and methods for behavioral modeling based on content genre and utilizing results for content recommendation and other network handling and storage of the content. Viewing events with respect to a content item are aggregated. An affinity is calculated based on the viewing events. Additional viewing events occurring during the delivery of the content item and associated with other content items are also selected. A sampling bonus is added to the affinity if these additional viewing events have a duration below a threshold and the other content items share a same genre as the content item.

  • Cognitive roaming support
    Patent number: 11843949
    Abstract: Methods and systems are described for generating and utilizing a pattern of association. The pattern of association can comprise information that indicates to which of a plurality of network devices one or more mobile devices are likely to connect. The pattern of association can comprise information that indicates an order of association. The pattern of association can be associated with one or more factors which can be any information that provides insight into the pattern of association. The pattern of association can be used to identify a next network device that a mobile device will transition to, based on which network device the mobile device is currently connected to. Data, such as authentication information, can be pushed to the identified next network device to reduce network connectivity issues that may occur by transitioning between network devices.
