Abstract
Systems and methods for providing closed captioning summarization. Various options may be provided to summarize different portions of a media item (e.g., a last 5 minutes, the last 15 minutes, from the beginning of the show). Upon receiving a request for a summary, a closed captioning summarization service may extract a portion of closed captions of a corresponding closed caption file and generate a prompt for a language model (LM) instructing the language model to summarize the extracted portion. A summary received from the LM may be presented on a display concurrently with the media item to provide a recapitulation of a desired portion of the media item to the user without disrupting play of the media item.
