Claim 6:
7. A computer system for determining a similarity value of a first content item of a first content type to a second content item of a second content type, the system comprising at least a processor and a memory, wherein the processor, in execution of one or more executable components, configures the computer system to:
determine a first embedding vector for the first content item for a first embedding space of the first content type;
determine a second embedding vector for the second content item for a second embedding space of the second content type;
identify a predetermined first number of closest items of the first content type to the first content item, each of the first number of closest items of the first content type having an established association to one or more content types of the second content type;
for each of the closest items to the first content item, identify a top content item of the second content type associated with a current closest item;
determine an averaged embedding vector in the second embedding space from embedding vectors of the top content items associated with the closest items to the first content item; and
determine a first similarity score between the first content item and the second content item according to a measure of similarity between the averaged embedding vector in the second embedding space and the second embedding vector of the second content item in the second embedding space.
