  • Patent number: 10366150
    Abstract: A digital magazine server receives a request from a user to create a section of a digital magazine including information identifying additional users authorized to modify content included in the section. For example, the request includes information identifying specific additional users or includes attributes associated with additional users. Based on information in the request, the digital magazine server identifies the additional users authorized to modify the content included in the section and notifies the additional user of their authorization to modify content included in the section. A modification to content included in the section is received from an additional user (e.g., identifying a content item, modifying content of a content item in the section), with the section generated based at least in part on the received modification. When the section is presented to digital magazine server users, the additional user providing the modification is also identified.

  • Patent number: 10341282
    Abstract: A digital magazine server presents content to a user that includes various content items. The user may provide a comment to the digital magazine server for association with a content item and may identify an additional user in the comment. To allow the user to more easily identify the additional user, the digital magazine server associates information identifying users who have performed actions with the content item in association with the content item. The digital magazine server compares information in a request to provide a comment to the information identifying the users who have performed actions with the content item and presents the user with information identifying users who have performed actions with the content item that at least partially matches a portion of the information in the request.

  • Patent number: 10298528
    Abstract: A digital magazine server receives user comments on content items of a digital magazine and generates comment threads. A comment thread has one or more user comments associated with a content item and at least one topic. A topic thread on a selected topic includes one or more comment threads related to the selected topic. To select comment threads for a topic thread based on the selected topic, the digital magazine server determines the relevance of the topic of each comment thread to the topic of the topic thread and determines the quality of the comment thread based on a plurality of quality factors such as number of comments and timestamps of the comments in a comment thread. The digital magazine server aggregates the comment threads based on at least one of topic relevance determination and thread quality determination and selects comment threads based on the aggregation.

  • Patent number: 10148775
    Abstract: An application associated with a digital magazine server receives actions from a user of the digital magazine server with content provided by the application. Additionally, the application obtains rules including suggested actions for the user to perform that are associated with actions previously performed by the user. As the user interacts with the application, the application captures information describing actions performed by the user and compares the actions performed by the user to the rules. If the application identifies a rule including information describing actions previously performed by the user that match captured actions, the application presents information identifying the suggested action in the identified rule to the user.

  • Patent number: 9971755
    Abstract: A digital magazine server provides a digital magazine including content items to a client device for presentation to a user. To increase user interaction with the digital magazine, the digital magazine server identifies a content item in the digital magazine and determines one or more topics associated with the identified content item. From the one or more topics, the digital magazine server identifies a topic and obtains candidate content items that are also associated with the identified topic. A candidate content item is selected from the candidate content item and the selected candidate content item is presented in conjunction with the identified content item.
