Ranking of content based on implied relationships

A system comprising:

• at least one processor;
• and
• a memory storing instructions that, when executed by the at least one processor, configures the system to:
• identify a plurality of result content items matching at least one criterion, the plurality of result content items identified from content items in a collection of content items;
• rank the content items in the plurality of result content items based on a similarity relationship between the content items in the plurality of result content items, and an influence relationship between pairs of the content items in the plurality of result content items, wherein:
• the similarity relationship between a first content item and a second content item is based on a comparison of embeddings of the first content item and the second content item in an embedding space derived, at least in part, from content metadata;
• and
• the influence relationship between the first content item and the second content item is based on aggregated signals indicative that user engagement with the first content item increases a propensity for user engagement with the second content item.

A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium comprising instructions that when executed, configure at least one processor to:

• identify a plurality of result content items matching at least one criterion, the plurality of result content items identified from content items in a collection of content items;
• rank the content items in the plurality of result content items based on a similarity relationship between the content items in the plurality of result content items, and an influence relationship between pairs of the content items in the plurality of result content items, wherein
• the similarity relationship between a first content item and a second content item is based on a comparison of embeddings of the first content item and the second content item in an embedding space derived, at least in part, from content metadata;
• and
• the influence relationship between the first content item and the second content item is based on aggregated signals indicative that user engagement with the first content item increases a propensity for user engagement with the second content item.
