Abstract: An access policy module automatically applies an access policy to a video. Access policies frequently require manual review of an item to determine a proper access policy for the video, such as whether the video should be taken down, age-limited, or permitted general access. Results of a manual review of a video are stored along with the portion of the video that was manually reviewed and the access policy applied to the video. When a trigger event occurs indicating access policies should be considered for a video, the video is compared to reviewed portions of videos that were manually reviewed to determine if an access policy can be automatically applied with sufficient confidence. When insufficient confidence is reached or conflicting access policies both have high confidence, the video is scheduled for manual review with a priority level based on the possible access level of the video.

Abstract translation: 访问策略模块自动将访问策略应用于视频。 访问策略通常需要手动审查项目以确定视频的适当访问策略，例如视频是否应该被取消，年龄限制或允许的一般访问。 手动审查视频的结果与手动审阅的视频部分以及应用于视频的访问策略一起存储。 当触发事件发生时，表示应该考虑视频的访问策略，视频被比较以查看手动审查的部分视频，以确定是否可以充分信心地自动应用访问策略。 如果达不到足够的信心或冲突的访问策略都具有很高的信心，则视频将根据视频的可能访问级别按照优先级进行手动审核。

Abstract: Methods, systems, and media for analyzing spherical video content are provided. More particularly, methods, systems, and media for detecting two-dimensional videos placed on a sphere in abusive spherical video content by tiling the sphere are provided. In some embodiments, the method comprises: receiving an identifier of a spherical video content item, wherein the spherical video content item has a plurality of views and wherein the spherical video content item is encoded into a plurality of two-dimensional video frames; selecting a first frame of the plurality of two-dimensional video frames associated with the spherical video content item; dividing the first frame into a plurality of tiles spanning the first frame of the spherical video content item; calculating, for each tile of the plurality of tiles, a probability that the tile includes content of a particular type of content; determining, for each tile, whether the probability exceeds a predetermined threshold; in response to determining, for a particular tile, that the probability exceeds the predetermined threshold, causing the content associated with the tile to be analyzed using a video fingerprinting technique; and in response to determining, using the video fingerprinting technique, that the content associated with the tile matches a reference content item of a plurality of reference content items, generating an indication of the match in association with the identifier of the spherical video content item.
