About What's in subtitles?


TV programs subtitles can be a rich source of information which main titles usually don't. Especially when talking about series, only the subtitle give some indication of the actual content of a program. For instance, take into consideration documentaries. This Master Project has the aim of showing how subtitles can improve the recall in recommender systems. Would subtitles be more effective than the description of the program? Can we extract keywords that can classify the program topic better? Shall we combine subtitles with other sources to reach a better result?
