System for Personalized Term Expansion and Recommendation

An apparatus, comprising:

• a processor;
• and
• a memory, at least one of the processor or the memory being adapted for:
• identifying a set of tags associated with one of a plurality of content items within a content sharing system, the content item being associated with a user of the content sharing system;
• for each one of the set of tags, identifying one or more global tag co-occurrences within the content sharing system, each of the global tag co-occurrences identifying a pair of tags including the one of the set of tags, wherein the pair of tags have both been used together to tag at least one of the plurality of content items within the content sharing system, thereby identifying a set of global tag co-occurrences for the set of tags;
• for each of one or more personal contexts of the content sharing system, identifying one or more personal tag co-occurrences used in the one of the one or more personal contexts of the content sharing system for each one of the set of tags, the one or more personal contexts relating to the user of the content sharing system, each of the personal tag co-occurrences identifying a pair of tags including the one of the set of tags that have both been used together to tag at least one content item within the corresponding one of the one or more personal contexts, thereby generating a set of personal tag co-occurrences for each of the personal contexts for the set of tags;
• generating a first set of recommended tags from the set of global tag co-occurrences and corresponding co-occurrence frequencies;
• generating an additional set of recommended tags from each of the one or more sets of personal tag co-occurrences and corresponding co-occurrence frequencies such that one or more additional sets of recommended tags are generated;
• and
• generating a single list of recommended tags from the first set of recommended tags and the one or more additional sets of recommended tags.

A method, comprising:

• identifying a set of tags associated with one of a plurality of content items within a content sharing system, the content item being associated with a user of the content sharing system;
• for each of two or more personal contexts of the content sharing system, identifying one or more personal tag co-occurrences used in the one of the two or more personal contexts of the content sharing system for each one of the set of tags, the two or more personal contexts relating to the user of the content sharing system, each of the personal tag co-occurrences identifying a pair of tags including one of the set of tags that have both been used together to tag at least one content item within the corresponding one of the two or more personal contexts, thereby generating a set of personal tag co-occurrences for each of the two or more personal contexts such that two or more sets of personal tag co-occurrences are generated;
• and
• generating a set of recommended tags from the two or more sets of personal tag co-occurrences and corresponding co-occurrence counts for each pair of tags in the two or more sets of personal tag co-occurrences.

A computer-readable medium storing thereon computer-readable instructions, comprising:

• instructions for identifying a set of tags associated with one of a plurality of content items within a content sharing system, the content item being associated with a user of the content sharing system;
• instructions for identifying a set of global tag co-occurrences for the plurality of content items within the content sharing system, each of the global tag co-occurrences in the set of global tag co-occurrences identifying a pair of tags that have both been used together to tag at least one of the plurality of content items within the content sharing system, each of the pair of tags in the set of global tag co-occurrences including one of the set of tags;
• instructions for identifying one or more sets of personal tag co-occurrences, each of the sets of personal tag co-occurrences being used in a corresponding one of one or more personal contexts of the content sharing system, the one or more personal contexts relating to the user of the content sharing system, each of the personal tag co-occurrences in the sets of personal tag co-occurrences identifying a pair of tags that have both been used together to tag at least one content item within a corresponding one of the one or more personal contexts, each of the pair of tags in the one or more sets of personal tag co-occurrences including one of the set of tags;
• and
• instructions for generating a set of recommended tags from the set of global tag co-occurrences and the one or more sets of personal tag co-occurrences.

A method, comprising:

• identifying a set of terms within a content sharing system, wherein the set of terms are associated with a user of the content sharing system, the content sharing system including a plurality of content items;
• for each of two or more contexts within the content sharing system, identifying a set of tag co-occurrences within the content sharing system for the set of terms, each of the set of tag co-occurrences identifying a pair of tags including one of the set of terms, wherein the pair of tags have both been used together to tag at least one of the plurality of content items within the corresponding one of the two or more contexts within the content sharing system, at least one of the two or more contexts being a personal context relating to the user of the content sharing system;
• and
• generating a set of recommended terms from the set of tag co-occurrences identified for each of the two or more contexts.
