Scalable Source Code Similarity Detection in Large Code Repositories

Understand

Source code similarity are increasingly used in application development to identify clones, isolate bugs, and find copy-rights violations.

• Similar code fragments can be very problematic due to the fact that errors in the original code must be fixed in every copy.
• Other maintenance changes, such as extensions or patches, must be applied multiple times.
• Furthermore, the diversity of coding styles and flexibility of modern languages makes it difficult and cost ineffective to manually inspect large code repositories.
