Tag selection and recommendation to a user of a content hosting service

A non-transitory computer-readable storage medium having executable computer program instructions embodied therein for selecting content object tags for recommendation to a user of a content hosting service, the computer program instructions configured to, when executed, cause a computer to:

• have a taxonomy of tags for labeling content objects to be stored within a content object corpus having over 100,000 content objects therein at the content hosting service, said taxonomy having a plurality of tag taxonomy branches;
• identify a baseline subset of content objects within said content object corpus based on a user context at the content hosting service, wherein said user context is one of:
• browsing for content objects, searching for content objects, or uploading content objects;
• identify a targeted subset of the baseline subset of content objects based on the user context, wherein each content object in the targeted subset of content objects is associated with one or more tags;
• determine a tag score for each tag associated with the targeted subset of content objects;
• determine a maximum number of tags to be recommended to the user based on available space within a user interface of said user;
• select tags with the highest recommendation score from a number of different tag taxonomy branches, as recommended tags to said user, said number being no more than said maximum number;
• receive tags selected by the user from among the recommended tags;
• and
• perform an operation on the content object corpus for the user context using the selected tags;
• receive tags selected by the user from among the recommended tags;
• and
• perform an operation on the content object corpus for the user context using the selected tags.

A computer system for selecting content object tags for recommendation to a user of a content hosting service, the system comprising:

• a computer processor;
• and
• a non-transitory computer-readable storage medium storing executable computer program instructions configured to, when executed by the processor, cause the computer system to:
• have a taxonomy of tags for labeling content objects to be stored within a content object corpus having over 100,000 content objects therein at the content hosting service, said taxonomy having a plurality of tag taxonomy branches;
• identify a baseline subset of content objects within said content object corpus based on a user context at the content hosting service, wherein said user context is one of:
• browsing for content objects, searching for content objects, or uploading content objects;
• identify a targeted subset of the baseline subset of content objects based on the user context, wherein each content object in the targeted subset of content objects is associated with one or more tags;
• determine a tag score for each tag associated with the targeted subset of content objects;
• determine a maximum number of tags to be recommended to the user based on available space within a user interface of said user;
• select tags with the highest recommendation score from a number of different tag taxonomy branches, as recommended tags to said user, said number being no more than said maximum number;
• receive tags selected by the user from among the recommended tags;
• and
• perform an operation on the content object corpus for the user context using the selected tags;
• receive tags selected by the user from among the recommended tags;
• and
• perform an operation on the content object corpus for the user context using the selected tags.
