摘要：Clone group mapping has a very important significance in the evolution of code clone. The topicmodeling techniques were applied into code clone firstly and a new clone group mapping methodwas proposed. By using topic modeling techniques to transform the mapping problem ofhigh-dimensional code space into a low-dimensional topic space, the goal of clone groupmapping was indirectly reached by mapping clone group topics. Experiments on four open sourcesoftware show that the recall and precision are up to 0.99, thus the method can effectively andaccurately reach the goal of clone group mapping.
