We used the so-called deterministic annealing algorithm due to Rose and Gurewitz by the classification of patent documents. The C++ program based on this algorithm was run first on some artificially constructed data and the results were good, then on some data sets obtained from some already classified patents. The conclusion we reached is that this algorithm provides an alternative classification to the one in the US Patent Classification System.
