| Outline of Final Research Achievements |
We have proposed a technique to detect code clones (hereafter, clones) from a large set of software projects. Our technique detects method-level clones while existing techniques detect file-level clones. We confirmed that our technique can finish detecting clones from 300 million lines of code. We also have proposed a technique to trace clones along development history of source code. Our technique can trace clones even if its location in a system was changed while existing techniques cannot. We confirmed that our technique takes about 3 hours to trace clones along 5,000 revisions of source code history.
