EviGraph: Towards Verifiable Evidence Construction for Information-Seeking Agents

EviGraph is presented, a deep-search framework that separates search execution from evidence recording while using a shared policy for the trainable roles, enabling reinforcement learning to directly supervise evidence construction rather than only the final answer.

SocialBuddy: Tailoring Search Agent for Social Scenarios

This work introduces SocialBuddy, the first agentic search framework tailored for social scenarios, and constructs SocialEnv, the first large-scale simulated environment for social search, which delivers multi-scale guidance in complex long-sequence scenarios.

WikiLoop: Jointly Learning to Build and Navigate Agent-Native Wikis with Downstream Feedback

Knowledge-base construction and querying are typically optimized in isolation: retrieval-augmented agents operate over a fixed, externally maintained index, whereas construction receives no signal from downstream use. We present WikiLoop, a feedback-coupled framework that jointly learns to build and navigate an agent-n...

IAPO: Influence-Aware Policy Optimization for Credit Assignment in Multi-Turn Service Agents

Influence-Aware Policy Optimization (IAPO), which represents each rollout as a typed influence-dependency graph over trainable agent actions, with user and tool observations serving as evidence, is introduced and advances the understanding of credit assignment in multi-turn user interactions.

Semantic Flow Regularization: Teaching LLMs to Generate Diverse Yet Coherent Responses

Semantic Flow Regularization (SFR), a lightweight auxiliary objective that supervises the backbone with continuous sentence-encoder embeddings of future segments via conditional flow matching, improves output diversity, style fidelity, and response quality over SFT on a large-scale industrial dialogue dataset.
