1. A method performed by one or more computer devices, the method comprising: identifying, by at least one of the one or more computer devices, a particular channel of a plurality of channels that provide content, determining, by at least one of the one or more computer devices, a respective first score for each of the plurality of content items, determining, by at least one of the one or more computer devices, a topic distribution for each of the plurality of content items, assigning, by at least one of the one or more computer devices, a second score to the particular channel, calculating, by at least one of the one or more computer devices and for each of the plurality of content items, a third score, calculating, by at least one of the one or more computer devices, a fourth score for the particular channel based on the third score calculated for each of the plurality of content items; normalizing, by at least one of the one or more computer devices, the fourth score to obtain a normalized score, calculating, by at least one of the one or more computer devices, a fifth score based on the normalized score and the second score; determining, by at least one of the one or more computer devices, a particular topic for which the particular channel is authoritative based on the fifth score; determining, by at least one of the one or more computer devices, that a difference between a time at which a new content item, relating to the particular topic, has been added to the particular channel and a current time is less than a threshold amount of time; and assigning, by at least one of the one or more computer devices, a sixth score to the new content item based on the fifth score, the particular channel being authoritative for the particular topic, and the difference being less than the threshold amount of time,
