Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data is retrieved from multiple external sources using web scraping, then data completeness and analysis accuracy are improved, but system complexity and data processing time increase
Solution Approach 1:
The system segments data retrieval operations into modular components: species data sources are separated from qualitative data sources, and each source type has dedicated retrieval logic. This modular segmentation manages complexity while enabling comprehensive multi-source data collection for accurate analysis.
Solution Approach 2:
The content management server acts as an intermediary that coordinates between multiple external data sources and the statistical modeling system. It manages the complexity of web scraping operations, data format variations, and integration logic, thereby improving analysis accuracy without proportionally increasing overall system complexity.
2Measurement precision
If multiple data sources are scraped and integrated, then data quality and model accuracy improve, but data processing time and computational resources increase
Solution Approach 1:
The system performs preliminary data retrieval and storage in structured databases (species data, qualitative data, factor databases) before statistical modeling begins. This preliminary organization of data from multiple sources reduces processing time during actual analysis while maintaining data quality and model accuracy.
Solution Approach 2:
The system transforms unstructured web data into standardized parameters and formats suitable for statistical modeling. By changing data parameters from various source formats into unified structured data, the system improves model accuracy while reducing the computational time required for processing during analysis.
3Reliability
If comprehensive data extraction from multiple sources is performed, then recommendation accuracy improves, but system resource consumption increases
Solution Approach 1:
The system extracts only the necessary and relevant data elements from comprehensive external sources using targeted web scraping. By extracting specifically needed information rather than processing all available data, the system maintains high recommendation accuracy while reducing overall resource consumption for data handling and processing.
