Description

Goal

Improve NLP model accuracy for query intent detection and complex multi-table query analysis.

Proposed Improvements

  • Train on larger corpus of complex queries
  • Add support for nested subquery semantic analysis
  • Implement context window expansion for multi-statement analysis
  • Improve JOIN intent detection (inner vs outer join semantics)
  • Add query goal classification (reporting, transactional, analytical)

Success Metrics

  • Intent classification accuracy >90%
  • Support for 3+ levels of nesting
  • Accurate semantic understanding of CTEs

  • analyzer/ml/analysis/unified_analyzer.py (was unified_query_analyzer.py)
  • analyzer/ml/analysis/cte_semantic_analyzer.py (CTE semantics)
  • analyzer/ml/analysis/join_semantic_analyzer.py (JOIN intent)

Research direction

Start by reading analyzer/ml/analysis/semantic_analyzer.py and analyzer/ml/analysis/unified_analyzer.py, then inspect cte_semantic_analyzer.py and join_semantic_analyzer.py to understand the current analysis flow. Compare existing behavior with the listed nesting, CTE, JOIN, context-window, and goal-classification requirements. Done means the stated accuracy and semantic-support metrics are met, but the issue does not identify tests or a narrower entry point.
