calculating a similarity score for each of the plurality of disclosed documents relative to the withheld document by applying a similarity function to the first and second array representations; and
associating, within the content-by-example log, an identifier for the withheld document with identifiers for the plurality of disclosed documents and their calculated similarity scores; and
providing the content-by-example log to the receiving party.
