Abstract
En 中文
• Proposes semantic image transformation by converting code ASTs into fixed-size grayscale images, reducing structural complexity and computational cost. • Integration of community detection, centrality analysis, and statement sequence embedding to capture both structural and semantic features of code. • Achieves high efficiency and accuracy for Type-4 (semantic) clone detection, outperforming 8 state-of-the-art methods on BigCloneBench and Google Code Jam datasets with significantly reduced computational time.
