Claim 14:
15. A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, causes the processor to perform a method for identifying videos containing objectionable content, the method comprising:
identifying a video that has been uploaded to a video sharing service;
generating an embedding for the video using a neural network, wherein the embedding specifies a location of the video in a multi-dimensional space where a plurality of videos are located based on content of the plurality of videos and wherein the neural network is trained using a plurality of anchor-positive-negative triplet examples that each include an anchor sample, a positive sample that is similar to the anchor sample, and a negative sample that is dissimilar to the anchor sample;
identifying from the plurality of videos a plurality of associated videos that each have an associated embedding that is located within a predetermined distance of the embedding of the video in the multi-dimensional space;
determining whether the video is likely to include a particular type of objectionable content by at least:
determining at least a predetermined amount of the plurality of associated videos that contain the particular type of objectionable content; and
determining a confidence level that the video includes the particular type of objectionable content based on the predetermined amount; and

in response to determining that the video is likely to include the particular type of objectionable content and in response to determining that the confidence level that the video includes the particular type of objectionable content is greater than a predetermined threshold, causing the video to be blocked from the video sharing service.
