Ranking content for display

A system for ranking content for display, comprising:

• hardware processing circuitry;
• one or more hardware memories comprising instructions that when executed configure the hardware processing circuitry to perform operations comprising:
• generating a statistics table that separately tracks content item views from content item selections across a plurality of users, the statistics table comprising:
• a first view count for a first content item and a first selected count for the first content item, the first view count being incremented each time the first content item is viewed by one or more users and the first selected count being incremented each time the first content item is selected by the one or more users of the plurality of users, and a second view count for the second content item and a second selected count for the second content item, the second view count being incremented each time the second content item is viewed by the one or more users and the second selected count being incremented each time the second content item is selected by the one or more users of the plurality of users;
• computing, based on the first and second view counts, a view number representing a quantity of users who viewed both the first content item and the second content item;
• determining, based on the first and second selected counts, that each user in a subset of the users, within an elapsed period of time comprising a same respective session, performed interactions in relation to the first content item and the second content item;
• computing a relevance value as a function of a quantity of users in the subset of users and the view number, the relevance value relating the quantity of users who selected and viewed the first and second content items to the quantity of users who viewed both the first and second content items without selecting one of the first or second content items;
• and
• determining relevance between the first and second content items based on the relevance value.

A non-transitory computer readable storage medium comprising instructions that when executed configure hardware processing circuitry to perform operations comprising:

• generating a statistics table that separately tracks content item views from content item selections across a plurality of users, the statistics table comprising:
• a first view count for a first content item and a first selected count for the first content item, the first view count being incremented each time the first content item is viewed by one or more users and the first selected count being incremented each time the first content item is selected by the one or more users of the plurality of users, and a second view count for the second content item and a second selected count for the second content item, the second view count being incremented each time the second content item is viewed by the one or more users and the second selected count being incremented each time the second content item is selected by the one or more users of the plurality of users;
• computing, based on the first and second view counts, a view number representing a quantity of users who viewed both the first content item and the second content item;
• determining, based on the first and second selected counts, that each user in a subset of the users, within an elapsed period of time comprising a same respective session, performed interactions in relation to the first content item and the second content item;
• computing a relevance value as a function of a quantity of users in the subset of users and the view number, the relevance value relating the quantity of users who selected and viewed the first and second content items to the quantity of users who viewed both the first and second content items without selecting one of the first or second content items;
• and
• determining relevance between the first and second content items based on the relevance value.
