Content aggregation and presentation

摘要

Techniques for providing personalized presentations of aggregated content items are described herein. These techniques may aggregate individual content items from multiple sources, filter the content items based on the preferences of a user, and create an ordered presentation of the content items. A different presentation may be available to the user at different times, for example, a new presentation may be available each day. The new presentation may include more recent or more relevant content items than previous presentations of content items. Each presentation may combine the multiple individual content items together in such a way that each individual content item appears to the user as part of a single content item. User interaction with the aggregation of content items may be analyzed and that analysis may be used to modify subsequent selection and ordering of content items in future presentations.
