METHODS AND SYSTEMS FOR ENHANCING METADATA

摘要

A method and system for utilizing metadata to search for media, such as multimedia and streaming media, includes searching for the media, receiving results, extracting metadata associated with the media, enhancing the extracted metadata, and grouping the search results in accordance with attributes of the enhanced metadata. Enhancing and grouping include adding related metadata to the database of metadata, iteratively using metadata to search for more media related data, removing duplicate URLs, collapsing URLs that are variants of each other, and masking out superfluous terms from URLs. The resultant metadata and media files are available to users and search engines.

1. A system for enhancing metadata, the system comprising:
a metadata obtaining section that obtains metadata of a media file; and an extraction agent that:
identifies, in a ground truth database, valid metadata that at least partially matches the obtained metadata; andmodifies the obtained metadata using at least a portion of the valid metadata so as to generate enhanced metadata, by
comparing contents in the obtained metadata with corresponding contents in the valid metadata,identifying contents in the valid metadata that are not in the obtained metadata, andadding the identified contents in the valid metadata to the obtained metadata.
