Videos can be inserted into knowledge panels. For example, relevant segments within a video can be captured and linked based on annotations in the video or using voice-to-text and natural language understanding. Segments can also be selected based on the frequency of a reference within the media or on the web. For example, if writing about President Kennedy's goal to put a man on the moon, the exact clip from his very famous speech can appear in a knowledge panel along with references of when he delivered the speech, to who, where, when, and other facts.

Knowledge panels showing that a user has authored an incorrect fact may be shown. For example, if a user authors a line of content to say a particular person was born in 1897, a knowledge panel with the correct date of birth of 1997 may be shown. The knowledge panel may be given a special presentation format to draw the user's attention. For example, the date of birth may be highlighted, the knowledge panel may be animated to pulse or appear to glow, and/or the presentation of the knowledge panel may be accompanied by an auditory alert.

Another type of application that may use knowledge panels is a personal assistant application or calendaring application. For example, in a work context, a user's next meeting can be shown in a knowledge panel that contains profiles of the people the user is meeting with, links to relevant emails, etc. The source documents for this information can include private data stored on a company's intranet, public information from, for example, social networking profiles, and/or other technologically appropriate sources.
