1. A computer-implemented method comprising the following operations performed via one or more processors: identifying, in a knowledge graph, at least one entity reference and related entity references related to the at least one entity reference by respective properties; for each respective one of the related entity references, determining a related entity score associated with a respective property that relates the at least one entity reference and the respective one of the related entity references; identifying a first entity type and a second entity type associated with the at least one entity reference, wherein the second entity type is a subtype of the first entity type; for each respective property, generating a property score based on related entity scores associated with that respective property, wherein generating a property score comprises aggregating the property scores for each property associated with the first entity type and the second entity type to generate an aggregated property score; and generating and causing to be stored a data structure of sortable properties based on the generated property scores, wherein the data structure is usable to provide sorted search results in response to a query.
