Apparatus and method for tracking temporal variation of video content context using dynamically generated metadata

An apparatus for tracking temporal variation of a video content context, the apparatus comprising:

• a processor configured to:
• generate static metadata based on internal data held during an initial publication of video content,
• tag the generated static metadata to the video content,
• collect external data related to the video content generated after the video content is published,
• generate dynamic metadata related to the video content based on the collected external data,
• tag the generated dynamic metadata to the video content,
• regenerate the dynamic metadata with an elapse of time,
• tag the regenerated dynamic metadata to the video content,
• track a temporal change in context of the regenerated dynamic metadata from the generated dynamic metadata, and
• generate and provide a trend analysis report of a context of the video based on the tracked temporal change in the context of the regenerated dynamic metadata,
• wherein the processor comprises:
• a first metadata generator/tagger configured to generate the static metadata based on the internal data held during the initial publication of the video content, and tag the generated static metadata to the video content,
• an external data collector configured to collect the external data related to the video content generated after the video content is published,
• a second metadata generator/tagger configured to generate dynamic metadata related to the video content based on the collected external data, and tag the generated dynamic metadata to the video content, and
• a dynamic metadata-based video context temporal variation tracker/analyzer configured to regenerate the dynamic metadata with the elapse of time, tag the regenerated dynamic metadata to the video content, track the temporal change in context of the regenerated dynamic metadata from the generated dynamic metadata, and generate and provide the trend analysis report of the context of the video based on the tracked temporal change in the context of the regenerated dynamic metadata,
• wherein the second metadata generator/tagger is further configured to expand and update topics and keywords of the static metadata using the collected external data and publication time information of the collected external data, and tag other metadata, along with publication time information of the other metadata, to the video content.
