Abstract: A digital magazine server receives user interactions with content items presented to users via various digital magazines. The digital magazine server retrieves interactions associated with a content item that are also associated with multiple digital magazines. From the retrieved interactions, the digital magazine server generates information describing global interactions with a content item that are associated with multiple digital magazines. The digital magazine server may filter interactions with the content item that are associated with different digital magazines based on characteristics of the interactions and the information describing global interactions with the content item generated based on the filtered interactions.

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.

Abstract: A digital magazine server generates an ownerless digital magazine for a community space. The digital magazine server is configured to receive a first sharing request for a community space from a user of the digital magazine server. In response, the digital magazine server creates a community space which includes a community space identification (ID) and an allocated storage space for the community space in the digital magazine server. The digital magazine server provides the community space ID to other users, who can contribute content to the community space through the digital magazine. The digital magazine server also automatically selects content not shared by the community members, where the digital magazine server identifies content for the community space, trains one or more models using various machine learning techniques to generate scores for the identified content, and selects identified content based on the scores for the community space.
