Engineering Contradiction Analysis
1Productivity
If sequential pattern mining technique is used to extract coding patterns, then coding patterns frequently appearing in source codes can be extracted, but coding patterns appearing at low frequencies cannot be extracted
Solution Approach 1:
The patent segments the source code into multiple abstraction levels (e.g., class level, method level, line level) and extracts patterns at each level separately. This allows low-frequency patterns to be captured at finer granularities while maintaining extraction efficiency through hierarchical processing
Solution Approach 2:
The patent changes the extraction parameters dynamically based on frequency thresholds and abstraction levels. By adjusting minimum frequency thresholds and pattern matching criteria at different abstraction levels, the system can extract both high-frequency and low-frequency patterns effectively
2Measurement precision
If manual analysis of all API adapters is performed, then comprehensive understanding of source code configuration is achieved, but a lot of labor is required
Solution Approach 1:
The system performs automatic pattern extraction and visualization without requiring manual analysis. The automated pipeline includes syntax analysis, pattern extraction, alignment generation, and visualization components that work autonomously to provide comprehensive source code understanding
Solution Approach 2:
The patent creates visual representations and abstracted copies of source code patterns that preserve essential structural information. These visual copies enable comprehensive understanding without requiring direct manual examination of the original source code
3Ease of operation
If source codes are abstracted to extract common patterns, then coding patterns can be visualized and recognized easily, but the complexity of the extraction and visualization process increases
Solution Approach 1:
The patent divides the complex extraction and visualization process into separate modular components: syntax analysis unit, pattern extraction unit, alignment generation unit, and visualization unit. Each component handles a specific task independently, making the overall system more manageable and easier to implement
Solution Approach 2:
The patent introduces alignment data as an intermediary representation between the abstracted patterns and the final visualization. This alignment information serves as a bridge that connects the abstract pattern representations with their visual displays, simplifying the overall processing architecture
