The research which exists suggests that a considerable portion (10-15%) of the source code of large-scale computer programs is duplicate code. Detection and removal of such clones promises decreased software maintenance costs of possibly the same magnitude. Previous paper was limited to detection of either near misses differing only in single lexemes, or near misses only between complete functions. This paper presents simple and practical methods for detecting exact and near miss clones over arbitrary program fragments in program source code by using abstract syntax trees.
