Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional crawlers are used for each website, then extraction accuracy can be maintained, but development and maintenance efforts increase and scalability decreases
Solution Approach 1:
The system employs machine learning models that automatically learn and adapt to different website structures without requiring manual programming for each site. The crawler self-adjusts its extraction rules by analyzing webpage patterns, eliminating the need for continuous manual development and maintenance of custom crawlers for each website.
Solution Approach 2:
A single universal crawler system is implemented that can handle multiple websites with different structures. The machine learning component enables this universal crawler to adapt its behavior across diverse website types, replacing the need for multiple specialized crawlers and significantly improving scalability.
2Measurement precision
If manual rules are specified for each website, then extraction precision can be ensured, but time consumption and costs increase
Solution Approach 1:
The system performs preliminary learning by training machine learning models on sample data from target websites before actual extraction. This pre-training phase enables the crawler to quickly adapt to website structures and achieve high extraction precision without requiring time-consuming manual rule specification for each new website.
Solution Approach 2:
Manual rule-based extraction systems are replaced with automated machine learning-based extraction. The ML models automatically learn extraction patterns from data, substituting the mechanical process of manual rule creation and maintenance with an intelligent system that adapts autonomously, thereby reducing both time and cost while maintaining precision.
3Reliability
If custom crawlers are developed for each website, then extraction quality can be maintained, but scalability to large numbers of websites deteriorates
Solution Approach 1:
The crawler system transitions from static, hard-coded rules to dynamic, adaptive behavior through machine learning. The system continuously learns from encountered websites and adjusts its extraction strategies in real-time, enabling it to maintain high extraction quality across diverse website types while scaling to large numbers of websites without requiring custom development for each.
