Abstract: Described herein are techniques for processing content items for presentation via a content feed of an online service. Upon receiving a request associated with a particular end-user of an online service for a content feed, a connection graph is analyzed to identify a plurality of content items that are eligible for presentation to the end-user. Some subset of content items that share a common relationship with the end-user, as indicated by a common edge in the connection graph, are identified. This subset of content items is then grouped together for presentation within the content feed in a content carousel, where the content carousel is positioned within the content feed, relative to other content items, based on the highest ranking content item presented via the content carousel.

Abstract: Systems and techniques for a member activity based profile viewing evaluation system are described herein. In an example, a profile viewing evaluation system is adapted to receive a viewed profile event indicating a member profile was accessed by a viewer, wherein the viewed profile event includes a member identification associated the member profile and a viewer identification associated with the viewer. The profile viewing evaluation system may obtain activity data related to activities performed by the member on the online service. The profile viewing evaluation system may obtain attributes of the viewer. The profile viewing evaluation system may determine the viewer is a notable viewer by comparing the attributes of the viewer to the activity data of the member. The profile viewing evaluation system may generate a graphical user interface to display viewer identification information associated with viewers of the member profile, including viewers classified as notable viewers.
