Abstract

Personalized content is generated from different media items using a content index. The content index is generated or updated by identifying segments of media items that are of particular interest to users. User interactions with the media items are analyzed and metadata of segments of media items that are determined to be of particular interest to the users is recorded. The parameters associated with a request for personalized content for a user are matched with the recorded metadata to identify relevant media items or segments of media items which are transmitted to the user as the personalized content.

10. The method of claim 8, wherein the first media item relates to a news event and the metadata comprises a type of news event, an identification of the news event, entities featured in the extracted segment, and additional metadata based on the news event.

11. The method of claim 8, wherein updating metadata in a content index further comprises:

updating, by the server computing device, the level of interest variable based on a respective number of the plurality of users associated with the selected user action.

12. The method of claim 1, further comprising:

receiving, by the server computing device, a second media item for extraction of segments;

identifying, by the server computing device, a domain-specific criterion associated with the second media item for the extraction;

extracting, by the server computing device, the segments comprising at least the first media item from the second media item based on the domain-specific criterion.
