Methods and apparatus to determine tags for media using multiple media features

A computing system comprising:

• a processor;
• and
• at least one memory storing instructions that, when executed by the processor, cause the computing system to perform operations comprising:
• assigning a first weight to a first feature extracted from an unknown media based on a first recognition technology to determine a weighted first feature, the first feature assigned to a first category of a plurality of categories;
• searching a pre-selected portion of a database comprising pre-tagged media, wherein the pre tagged media included in the pre selected portion of the database comprises category values that match the first category of the first feature, wherein searching the pre-selected portion of the database comprises searching with a combination of weighted features to generate a list of suggested tags for the unknown media, the list of suggested tags including relevancy scores for respective ones of the tags in the list, the combination of weighted features including the weighted first feature;
• and
• assigning a tag from the list of suggested tags to the unknown media based on a comparison of the relevancy score for the tag to a threshold.

A non-transitory computer readable storage medium having stored thereon program instructions that, upon execution by a processor, cause performance of operations comprising:

• assigning a first weight to a first feature extracted from an unknown media based on a first recognition technology to determine a weighted first feature, the first feature assigned to a first category of a plurality of categories;
• searching a pre-selected portion of a database comprising pre-tagged media, wherein the pre-tagged media included in the pre-selected portion of the database comprises category values that match the first category of the first feature, wherein searching the pre-selected portion of the database comprises searching with a combination of weighted features to generate a list of suggested tags for the unknown media, the list of suggested tags including relevancy scores for respective ones of the tags in the list, the combination of weighted features including the weighted first feature;
• and
• assigning a tag from the list of suggested tags to the unknown media based on a comparison of the relevancy score for the tag to a threshold.
