Hybrid audio-visual categorization system and method

摘要

Meta-data (tags) for an audiovisual file can be generated by prompting a user to input tags (meta-data) descriptive of the audiovisual file, to serve as an initial estimate of the tags, and then revising the estimate (notably to expand it and/or render it more precise) based on the assumption that the relationships which hold between the different tags for a set of manually-tagged training examples will also hold for the tags of the input file now being tagged.
