Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for computing transitive closures of relations. One of the methods includes initializing the transitive closure F of an initial iteration with the tuples in another relation f. New first tuples and new second tuples are iteratively computed until no new first tuples are generated, including: generating new first tuples on each iteration by matching destination elements of tuples in the auxiliary relation of a previous iteration with source elements of tuples in the auxiliary relation of the previous iteration, generating second tuples on each iteration by matching destination elements of the new first tuples with source elements of tuples in F of the previous iteration, and adding the new first tuples and the new second tuples to F of a current iteration.
