Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for obtaining first position information of a first user interaction with a multimedia content item that is presented at a first time to the first user in a presentation area on a first computer device; obtaining, in response to obtaining the first position information, second position information of a second user interaction with the multimedia content item that was presented at a second time to a second user in a presentation area on a second computer device, the second time occurring before the first time; calculating a correlation score that is indicative of the relatedness of the second user interaction to the first user interaction; and in response to the correlation score meeting a threshold value, providing a first data set provided by the second user and associated with the first user interaction to the first user. |
