Abstract

A media content item is evaluated for its “sentiment states.” That is, segments of the content item are determined to be, for example, “happy,” “exciting,” “sad,” “funny,” and the like. A “sentiment map” is created that delimits segments of the content item and contains the sentiment-state keywords associated with the segments. Some maps include an amplitude for each assigned sentiment keyword and a confidence value for the segment delimitation and for each keyword. As an exemplary use of the sentiment map, an advertisement broker matches the sentiments of his advertisement offerings with segments of a content item in order to place appropriate advertisements at times when they would be most favorably received. In another example, a recommender system recommends to a user a content item whose sentiment map compares favorably to that of a content item already enjoyed by the user.

a broadcast television channel, a cable television channel, a broadcast radio channel, a private radio channel, a satellite-provided channel, the Internet-provided channel, and a local content-storage device.

5. The method of claim 1 wherein evaluating, delimiting, associating, and storing are performed, at least in part, before the receiving of the media content item is complete.

6. The method of claim 1 wherein delimiting is based, at least in part, on metadata associated with the media content item.

7. The method of claim 1 wherein delimiting is based, at least in part, on the evaluating.

8. The method of claim 1 wherein the delimited segment comprises the entire media content item.

9. The method of claim 1:

wherein delimiting comprises delimiting a plurality of segments of the media content item; and

wherein at least two of the plurality of delimited segments overlap.

10. The method of claim 1 wherein the sentiment-state keyword is selected from the group consisting of:

happy, sad, funny, successful, romantic, exciting, violent, unknown.

11. The method of claim 1 wherein associating further comprises associating a plurality of sentiment-state keywords with the delimited segment.

12. The method of claim 1:

wherein the media content item comprises metadata associated with the delimited segment; and

wherein evaluating is based, at least in part, on evaluating at least a portion of the metadata associated with the delimited segment.

13. The method of claim 12 wherein the metadata are selected from the group consisting of:

text, an electronic program guide, closed-captioning information, a script, and staging instructions.

14. The method of claim 1 wherein evaluating is based, at least in part, on evaluating social-response information associated with the delimited segment.

15. The method of claim 1 wherein evaluating is based, at least in part, on evaluating information specific to a consumer of the media content item, the information selected from the group consisting of:

health information, demographic information, preference information, social-group information, Internet-use information, behavioral information, software-use information, purchase information, content-consumption information, contextual information, and peer-presence information.

16. A method for analyzing a media content item, the method comprising:

evaluating, by the media analyzer, at least a portion of the media content item;

delimiting, by the media analyzer, a segment of the media content item;

based, at least in part, on the evaluating, associating, by the media analyzer, a sentiment-state keyword with the delimited segment; and

storing, by the media analyzer, a map of the delimited segment, the map comprising the associated sentiment-state keyword and a delimitation of the segment;

wherein the delimited segment comprises an element selected from the group consisting of;

audio content and video content;

wherein the associating is based, at least in part, on an evaluation of an element selected from the group consisting of;

audio content of the delimited segment and video content of the delimited segment;

wherein delimiting comprises associating a confidence value to the delimitation of the segment; and

wherein storing comprises storing the delimitation confidence value in the map of the delimited segment.
