Systems and methods are described for determining a likelihood and degree of derivation among media content items. In one example, a processing device processes a first media content item in relation to one or more other media content items to identify one or more similarities between the first media content item and one or more other media content items. The processing device determines, based on an identification of the one or more similarities between the first media content item and one or more other media content items, one or more derivation metrics with respect to the first media content item and one or more other media content items. The processing device initiates, based on a determination of the one or more derivation metrics, one or more actions with respect to the first media content item and/or one or more other media content items.
