RL-Index: Reinforcement Learning for Retrieval Index Reasoning

arXiv:2606. 16316v1 Announce Type: cross Abstract: Retrieving external knowledge is essential for solving real-world tasks, yet it remains challenging when the relationship between a query and its relevant knowledge involves implicit and complex reasoning beyond surface-level semantic or lexical matching (e.

PersonalAI 2.0: Enhancing knowledge graph traversal/retrieval with planning mechanism for Personalized LLM Agents

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.

VikingRAG: Accurate and Token-efficient Retrieval-augmented Generation over Structured Documents

VikingRAG is a directory‑aware semantic data management system that reduces token usage in retrieval‑augmented generation by tightly integrating semantic and structural access. It employs multi‑round retrieval traces as reusable experience edges and an adaptive escalation strategy to avoid unnecessary multi‑round exploration. Experiments show that VikingRAG achieves comparable accuracy to state‑of‑the‑art methods while using only 11.6%–51.9% of their tokens, and further reductions to 5.1%–32.5% with trace reuse and escalation.
