Challenges & Solutions
Challenge 1: Patent Text Complexity
Patent documents contain highly technical language and legal terminology that standard NLP models struggle to process. The solution involved fine-tuning the BART model on a large corpus of patent text, enabling it to understand domain-specific vocabulary and technical concepts.
Challenge 2: Geographic Data Quality
Patent location data was often incomplete or inconsistent across different patent offices. This was resolved by implementing a multi-source geocoding system with address standardization and coordinate validation to ensure accurate spatial analysis.
Challenge 3: Economic Correlation Analysis
Establishing causal relationships between patent activity and economic outcomes required sophisticated statistical modeling. The solution involved implementing time-series analysis, controlling for confounding variables, and using multiple economic indicators for robust correlation analysis.
