Unsupervised video segment clustering and boundary positioning

A system comprising:

• one or more computer processors;
• and
• one or more memories collectively containing one or more programs which when executed by the one or more computer processors performs an operation, the operation comprising:
• accessing a plurality of videos;
• generating an index for the plurality of videos based on one or more key frames and one or more video features extracted from each respective video of the plurality of videos;
• processing a user input to identify user intentions;
• filtering the index to identify a plurality of candidate key frames based on the user intentions;
• and
• generating a recommended video based on the plurality of candidate key frames, comprising:
• selecting one or more additional frames based on processing the plurality of candidate key frames using one or more clustering operations;
• and
• aggregating the plurality of candidate key frames and the one or more additional frames.
