Abstract: Methods and systems are disclosed for delivering content to users. In one embodiment, a computer system obtains text associated with a content item, where the text comprises: text from a transcript associated with a content item, when available; text from a web feed (e.g., an RSS feed, etc.) associated with the content item, when available; text from a webpage associated with the content item, when available; and text that is returned from a call to an application programming interface (API) of a provider of the content item, when available. The computer system then determines a set of entities based on the obtained text.
