DE-DUPLICATING COMBINED CONTENT

摘要

A system, method, and apparatus for de-duplicating and serving a combined content feed are provided. The combined content includes items of two or more classes, such as sponsored and unsponsored, wherein some or all unsponsored content items may be sponsored. A feed service obtains sponsored and unsponsored items suitable for a user to whom the combined content feed is to be served. The service determines whether an item is duplicated among the multiple classes. If so, a distance between the duplicates is calculated (within the feed). If the distance is less than a first threshold, one of them is discarded and may or may not be replaced. A decision regarding which to eject may depend upon which version (e.g., sponsored or unsponsored) is positioned earlier in the feed, whether the duplicates are also less than a second threshold apart (which is lower than the first threshold), and/or other factors.

1. A computer-implemented method of de-duplicating combined content, the method comprising:
receiving a user connection at a content-serving system comprising one or more processors; and operating the one or more processors to:
for each of multiple classes of content, obtain multiple content items;determine a position of each of the obtained content items within a content feed to deliver to the user in response to the connection; andfor each obtained content item duplicated among the multiple classes:
calculate a distance, within the content feed, between the duplicate items; anddiscard one of the duplicate items from the feed if the distance is less than a first threshold distance.
