When a user selects content to share, some operating systems present a user interface in which the user is shown a shortcut to share the content with particular contacts and/or via particular applications. However, such suggestions often do not match the user’s intent and are therefore inaccurate and accordingly, have low click-through rates. This disclosure describes techniques, implemented with user permission, to assign an affinity signal to a given piece of content, such that the suggestion interface offers the most relevant contacts to share the content with. The affinity signal is based on the content as well as the context, determined with user permission.
