Researchers introduce A.DOT Planner, an AI framework that enables multi-hop question answering across hybrid data lakes containing both structured and unstructured data. The system uses directed acyclic graphs to orchestrate complex queries, achieving 14.8% better accuracy and 10.7% better completeness than existing solutions.
Researchers present an automated system that discovers executable schemas from multi-source, heterogeneous data and uses them as a unified contract for knowledge graph construction and intelligent query routing. The approach combines LLM-based schema discovery with deterministic structural analysis and demonstrates improved retrieval performance across four QA benchmarks compared to baseline methods.
Researchers introduce Sophrosyne, a system that improves Text2SQL agents by moderating their exploration of database APIs. The solution addresses over-exploration by fine-grained APIs, reducing unnecessary schema queries by 4.6x while improving SQL generation accuracy by up to 12.4 percentage points.
Researchers present a framework for integrating AI directly into database engines (AIxDB) to reduce overhead and improve security compared to exporting data to separate ML runtimes. The paper addresses technical challenges including query optimization, resource management, and security controls needed for effective AI-database integration.
Researchers developed AWARE-US, a system to improve AI agents' ability to handle failed database queries by intelligently relaxing the least important user constraints rather than simply returning 'no results'. The system uses three LLM-based methods to infer constraint importance from dialogue, achieving up to 56% accuracy in correct constraint relaxation.
Researchers introduce DevRev-Search, an automated system for building multi-tenant search systems that addresses the challenge of underutilized query data in enterprise environments. The system uses LLM-based relevance labeling and query-only fine-tuning to improve search performance while avoiding costly full corpus re-indexing.
