Abstract: In order to facilitate access to relevant information, a system may determine topics that are of interest based on skills of users in a social network of users and annotations associated with content in the social network. Then, the system may identify experts knowledgeable about the topics among the users in the social network. These experts may be invited to aggregate and edit the topic content. For a given topic, the system may provide, to a subset of the experts, documents with suggested topic content and presentation formats for the topics. Based on feedback from the subset of the experts (such as modifications to one or more of the documents and/or the presentation formats), the system may modify or revise the documents.

Abstract: In order to facilitate access to and exchange of a given content item in a sequential set of content items (such as a slide in a presentation or a frame in a video), a system may create a clipped-content identifier in response to a clip selection of the content item by a user. This clipped-content identifier may include a pointer to a location in the system that stores the content item in the sequential set of content items, and metadata associated with the content item. Subsequently, the system may present a clipped-content summary document to the user, which allows the user to download, edit, share, and aggregate one or more clip selections in sequential sets of content items.

Abstract: During a user-interface technique, a user interface that includes information associated with a set of presentations is displayed on an electronic device. In this user interface, the presentations are arranged in different categories along a vertical direction of the user interface in an order that is determined based on presentation preferences of a user of the electronic device and/or presentation activities of a group of individuals associated with the user. Furthermore, thumbnails or tiles associated with pages of individual presentations in the set of presentations are arranged along a horizontal direction of the user interface. Subsequently, in response to the user input, the displayed user interface is modified. For example, if the user input specifies a vertical displacement, the set of presentations is displaced along the vertical direction. Alternatively, if the user input specifies a horizontal displacement, the thumbnails for a given presentation are displaced along the horizontal direction.
