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 introduced LakeQA, a new benchmark dataset for evaluating large language models on question-answering tasks over massive data lakes containing 9.5TB of heterogeneous data. The benchmark reveals significant challenges in current LLMs, with GPT-5.2 achieving only 18.37% accuracy, highlighting the gap between reading-comprehension performance and real-world search-and-reasoning requirements.
Researchers introduce KramaBench, a comprehensive benchmark testing AI systems' ability to execute end-to-end data processing pipelines on real-world data lakes. The study reveals significant limitations in current AI systems, with the best performing system achieving only 55% accuracy in full data-lake scenarios and leading LLMs implementing just 20% of individual data tasks correctly.
