US Patent 9734248 Interest-based message-aggregation alteration

A communication engine collects a first topic of a first user. The communication engine retrieves a message-aggregation from a content delivery repository. The message-aggregation includes a plurality of messages and a title. The message-aggregation is generated by a content provider before retrieval. The communication engine detects a relevant first message in the plurality of messages based on the first topic. The communication engine alters the message-aggregation such that the relevant first message is distinguished from the plurality of messages other than the first message. The alteration is based on the detected relevant first message. The communication engine also alters the title of the message-aggregation based on the detected relevant first message.
