PersonalAI 2.0 (PAI‑2) is a new framework that improves large language model (LLM) systems by integrating external knowledge graphs through a dynamic, multistage query‑processing pipeline. It performs adaptive, iterative information search guided by extracted entities, matched graph vertices, and generated clue‑queries, and has been evaluated on five benchmarks (Natural Questions, TriviaQA, HotpotQA, 2WikiMultihopQA, and MuSiQue). The results show a 9% average gain in factual correctness over comparable methods, an 18% boost from the search‑plan enhancement mechanism, and state‑of‑the‑art performance on the MINE‑1 benchmark, indicating that PAI‑2 effectively reduces hallucinations and increases precision for personalized AI applications.

SAG (SQL‑Retrieval Augmented Generation) is a structured retrieval framework that indexes documents as event‑entity pairs, forming latent hyperedges that preserve n‑ary relations without building a global knowledge graph. At query time, shared entities act as join keys, dynamically creating a query‑scoped neighborhood of related events while keeping each evidence chunk intact. Experiments on HotpotQA, 2WikiMultiHopQA, and MuSiQue demonstrate that SAG outperforms existing dense‑retrieval baselines, achieving the highest recall and end‑to‑end QA performance, especially as reasoning‑chain complexity grows.
