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.

Abstract: Methods and systems for improving precision of content matching systems at a platform are provided herein. A media item associated with a user of a platform as input to a machine learning model. One or more outputs of the machine learning model are obtained. The outputs indicate a level of confidence that at least one content segment of the media item matches content of a reference media item associated with another user of the platform in view of a content category associated with the media item. Responsive to a determination that the at least one content segment of the media item matches the content of the referenced media item in view of the content category, one or more actions are caused to be initiated to prevent one or more users of the platform from accessing the at least one content segment of the media item.

Abstract: Methods and systems for improving precision of content matching systems at a platform are provided herein. Candidate matches for a media item are obtained. Each of the candidate matches indicates a reference media item including content that corresponds to content of the media item. Similarity data associated with the media item and the reference media items of the candidate matches is provided as input to a machine learning model. A determination is made, based on outputs of the model, of a content category associated with the media item and whether content of the media item matches content of a respective reference media item of the candidate matches in view of the determined content category. If so, action is taken to prevent users from the platform from accessing the content of the media item.
