Hierarchy-trans: First direct attempt to utilize hierarchical values for code structure comprehension.
Hierarchy-Aware Attention: Incorporates hierarchical features into model embeddings and attention matrix computation.
Indentation-Based Hierarchy: Extracts hierarchical values from indentation levels, offering a simpler and more efficient alternative to ASTs.
Dual Integration: Hierarchy values used as absolute token features and relative distances for attention calculation.
AST Integration: Can be combined with AST-derived distances (Shortest Path, Ancestor, Sibling, PageRank) for enhanced performance.
Efficiency: Achieves comparable or superior performance with significantly lower computational cost by avoiding complex AST processing.
Accuracy: Outperforms traditional baselines in code summarization across multiple languages (Python, Javascript, Ruby, Go, Java).
Interpretability: Hierarchical values directly reflect programming semantic expression, aiding model understanding.
Scalability: Negligible space overhead and faster processing suitable for large-scale codebases.
Complementarity: Hierarchical values complement AST information, providing robust structural cues, especially local, intra-block relationships.
F1 Score Boost: Significant F1 score improvements, with Python achieving 36.40% (hierarchy-only) and higher with AST combinations.
Resource Advantages: Hierarchy extraction is O(n) vs. O(n²) for AST, leading to substantial time and memory savings.
Language-Specific Performance: Strong gains in Python and JavaScript, moderate in Ruby and Go due to dynamic typing/terse syntax.
Robustness: Hierarchical values enhance model robustness, even in languages like Java not strictly enforcing indentation.
Future Work: Exploring dynamic languages, auxiliary methods, and scalability for larger models.

Improved Python Code Summarization
In Python, Hierarchy-trans (hierarchy-only) achieved an F1 score of 31.96%, surpassing traditional baselines. When augmented with AST, the model reached 36.40% F1. This demonstrates the significant contribution of hierarchical information, especially its ability to capture specific intra-block relationships that AST alone might miss or overcomplicate.
