Which bodes well for its credentials! bX data-mines log files from link resolvers:
The bX service derives its recommendations from the analysis of tens of millions of transactions performed by users from research institutions worldwide and captured through a large-scale aggregation of link resolver usage logs.
So it probably uses only Collaborative Filtering rather than a hybrid (content-based) scheme. It probably doesn’t use citations either.
Not having seen a link resolver log, I don’t know if there’s user-identity information to be found there beyond the IP address. If there isn’t that could muddy the waters somewhat. Librarians (with the same IP address) often act on behalf of a wide variety of end-users which could lead to rather meaningless serendipity in the recommendations.
