Precision of content matching systems at a platform

A system comprising:

• a memory device;
• and
• a processing device coupled to the memory device, the processing device to perform operations comprising:
• providing a media item associated with a user of a platform as input to a machine learning model;
• obtaining one or more outputs of the machine learning model, wherein the one or more 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;
• determining, based on the one or more obtained outputs, whether the at least one content segment of the media item matches the content of the reference media item in view of the content category;
• and
• responsive to determining 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, causing one or more actions to be initiated to prevent one or more users of the platform from accessing the at least one content segment of the media item.

A non-transitory computer readable storage medium comprising instructions for a server that, when executed by a processing device, cause the processing device to perform operations comprising:

• providing a media item associated with a user of a platform as input to a machine learning model;
• obtaining one or more outputs of the machine learning model, wherein the one or more 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;
• determining, based on the one or more obtained outputs, whether the at least one content segment of the media item matches the content of the reference media item in view of the content category;
• and
• responsive to determining 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, causing one or more actions to be initiated to prevent one or more users of the platform from accessing the at least one content segment of the media item.
