A method includes receiving first data associated with a first user profile including a first set of ranked items and a first title having one or more keywords. The method further includes identifying second data associated with a second user profile including a second set of ranked items and a second title including one or more keywords. The first title and the second title are within are threshold proximity based on the keywords of the first title and the second title. The method further includes determining that the first set of ranked items is most similar to the second set of ranked items by performing a rank-weighted similarity comparison.
