More generally, it presents a technique for aggregating user-generated tags from accounts in multiple services and generating a user profile. However, it's not clear what we gain from these other components. The account correlation component of the architecture is intended to capture different aspects of the user's interests, but doesn't seem essential to the technique. The generation of a FOAF file as the end result of profile generation seems a little arbitrary. Would the paper have benefited from a discussion of how the generated profile can ultimately be used to provide benefit to the user (e.g. by mapping interests back to original tags in each of the source web services and using these for recommendation)? vices and using these for recommendation)?
