DynaTree: Dynamic Agentic Retrieval Tree for Time-Sensitive News Retrieval
DynaTree is a two-stage framework for efficient news retrieval that combines offline agentic reasoning with lightweight online subtree selection, achieving significant improvements in real-world deployment. The system demonstrated a 59-73% survival rate versus 32-53% for fixed approaches in production A/B testing, highlighting the practical value of persistent semantic expansion for time-sensitive information retrieval.
