Application ID: 14658311

Base Claim:
1. A computer-implemented method, comprising: identifying image features in images from a plurality of distinct content items; determining that, for a subset of the distinct content items, the content items in the subset each have respective images that have at least a minimum number of the identified image features in common; generating implicit links between the content items in the identified subset based on determining that the content items in the subset have at least the minimum number of the identified image features in common; assigning weightings to the implicit links between the subset of the content items; and determining a rank score for at least one of the content items in the subset based at least in part on the weightings of the implicit links, the rank score being a value indicative of the importance of the content item relative to others of the distinct content items.

Claim 5:
5. The computer-implemented method of claim 1 , wherein assigning the weightings to the implicit links comprises assigning, to a particular implicit link between a first content item of the distinct content items and a second content item of the distinct content items, a weighting determined based at least in part on a number of identified image features in common between an image of the first content item and an image of the second content item.
