Keyword-tagging of scenes of interest within video content
First Claim
1. A method of extracting scenes of interest from video content, the method comprising:
- collecting a plurality of comments with posting timestamps indicating times at which the comments were posted, from a comment server, the comments containing keywords associated with the video content;
segmenting the video content into a plurality of scenes;
measuring a number of ones of the plurality of comments which were posted during a time zone of each scene, as a post count;
calculating an average μ
post count per scene and a standard deviation σ
of the post counts among each of the scenes;
detecting ones of the plurality of scenes having a post count equal to or larger than a sum of the average μ and
the standard deviation σ
as a plurality of scenes of interest; and
for each of the scenes of interest;
extracting at least one of the keywords which is contained in the plurality of comments with a number equal to or larger than a pre-selected number, as a comment keyword; and
tagging the scene of interest with the comment keyword.

Abstract
Extraction of scenes of interest from video content is disclosed, which includes: collecting comments from a comment server, which contain keywords associated with the video content; segmenting the video content into scenes; measuring the number of ones of the comments which were posted for each scene, as a post count; detecting ones of the scenes, each of which has the post count equal to or larger than a predetermined number, as a plurality of scenes of interest; extracting, per each scene-of-interest, at least one of the keywords which is contained in the comments with a number equal to or larger than a pre-selected number, as a comment keyword; and tagging each scene of interest with the comment keyword, per each scene-of-interest.
