ToE: A Hierarchical and Explainable Claim Verification Framework with Dynamic Multi-source Evidence Retrieval and Aggregation
arXiv:2606.27736v1 Announce Type: new Abstract: The rapid spread of fake news poses increasing threats to information ecosystems, especially as AI-generated misinformation under Generative Engine Optimization (GEO) poisoning allows adversarially crafted content to be systematically surfaced by retrieval systems, contaminating LLM reasoning. In this paper, we propose Tree of Evidence (ToE), a hierarchical evidence reasoning framework for automated fact-checking that models each claim as a dynamically expanding argument tree. ToE integrates a reinforcement learning-driven multi-source retrieval
The proliferation of AI-generated misinformation and 'Generative Engine Optimization' makes advanced fact-checking frameworks critically necessary to preserve information integrity.
This framework directly addresses the growing threat of AI poisoning critical reasoning systems, which is essential for maintaining trust in digital information and the reliability of LLM outputs.
The development of hierarchical, explainable, and dynamic multi-source verification systems represents a significant leap in combating sophisticated AI-driven disinformation.
- · Fact-checking organizations
- · Information security firms
- · Generative AI developers focusing on verification
- · Individuals and institutions reliant on accurate information
- · Misinformation actors
- · Platforms unable to integrate robust verification
- · Legacy fact-checking methods
This framework could significantly improve the accuracy and trustworthiness of information retrieved and processed by large language models.
Increased trust in AI-processed information could accelerate the adoption of AI agents in sensitive domains, provided their reasoning is verifiable.
The development of such robust verification tools might initiate an 'information arms race' where increasingly sophisticated disinformation tactics are met with equally advanced detection and debunking technologies.
