1. A method of creating a semantic summary of a video comprising the steps of:
- (a) identifying a domain of said video;
(b) using said domain to locate information related to said video at a source other than said video;
(c) extracting a datum related to a semantic event from said information, said semantic event describing a portion of said video;
(d) identifying said portion of said video related to said datum; and
(e) creating a summary of said identified portion of said video in response to the extraction of said datum.

Abstract
Creating semantic summaries and abstractions of video requires high level knowledge of the domain of the video. Obtaining this high level information without human intervention is problematic. A method of producing video summaries and abstractions is provided where high level knowledge necessary for meaningful summarization is obtained from existing sources such as the worldwide web or an electronic programming guide. With this information, the summarization system can automatically identify significant events or subjects and extract video related to these events or subjects.

7. A method of abstracting video comprising the steps of:
-
(a) locating an index of said video from a source external to said video; (b) identifying a domain of said video for creating a video abstraction; (c) using said domain together with said index to identify portions of said video for inclusion in said video abstraction; (d) extracting said identified portions of said video from said video to form said video abstraction in response to the location of said index; and (e) displaying said video abstraction to a user. - View Dependent Claims (8, 9, 10)

11. A method of creating a semantic summary of a video comprising the steps of:
-
(a) identifying a domain of said video; (b) using said domain to locate a textual summary of said video; (c) extracting a datum related to a semantic event relevant to said video summary from said textual summary; (d) locating content in said video corresponding to said datum; and (e) extracting said content related to said semantic event from said video in response to extraction of said datum from said video for inclusion in said semantic summary including at least one portion of said video.

12. A method of abstracting video comprising the steps of:
-
(a) locating an index of said video in at least one of a worldwide web site and a programming guide; (b) identification of a domain of said video for creating a video abstraction by a user; (c) using said domain together with said index to identify portions of said video for inclusion in said video abstraction; and (d) extracting said identified portions of said video from said video to form said video abstraction.
