The Future of Facts: Tracing the Factual Generation-Verification Gap

Researchers reveal that language models verify factual information more reliably than they generate it, a phenomenon driven by distinct training dynamics rather than computational limitations. The study traces this generation-verification gap across model families and training phases, finding that models can simultaneously accept contradictory facts after updates, creating consistency issues for AI systems deployed as knowledge interfaces.

From Unstructured Recall to Schema-Grounded Memory: Reliable AI Memory via Iterative, Schema-Aware Extraction

Researchers propose a schema-grounded approach to AI memory that treats persistent storage as a system of record rather than a search problem, using iterative extraction with validation gates. The method achieves 97.10% F1 on memory benchmarks and 95.2% accuracy on application tasks, significantly outperforming retrieval-based baselines and suggesting that memory architecture matters more than model scale alone.

Bilinear representation mitigates reversal curse and enables consistent model editing

Researchers have identified that the 'reversal curse' in language models - their inability to infer 'B is A' from 'A is B' - can be overcome through bilinear representation structures. Training models on synthetic relational knowledge graphs creates internal geometries that enable consistent model editing and logical inference of reverse facts.

Some Results about the Expressivity of Preference-Incomplete Structured Argumentation Frameworks

This academic paper investigates the expressive power of ASPIC+ argumentation frameworks when preference information is incomplete, comparing them against abstract formalisms with uncertain defeats. The research yields mostly negative results regarding expressivity limitations, while proposing a conjecture about a potential threshold for uncertain preference frameworks.

Constructing Evaluation Datasets for Procedural Reasoning: Balancing Naturalness, Grounding, and Multi-Hop Coverage

Researchers present a framework for evaluating procedural reasoning datasets in AI-supported learning systems by comparing three question-generation strategies based on Task-Method-Knowledge (TMK) models. The study demonstrates that strict TMK generation produces the most grounded and usable datasets (96.5% grounded), while transcript-based approaches sacrifice representational alignment for naturalness, highlighting the trade-off between learner-like phrasing and formal grounding in evaluation dataset construction.

Standpoint Logics with Defeasible Beliefs

This paper integrates defeasible logic with standpoint logic to formally model knowledge across multiple contradictory viewpoints that may hold uncertain beliefs. The work provides theoretical foundations for Defeasible Restricted Standpoint Logics (DRSL) and proves that computational complexity remains unchanged when extending propositional KLM entailment relations to multi-standpoint settings.

Self-Revising Discovery Systems for Science: A Categorical Framework for Agentic Artificial Intelligence

Researchers present a category-theoretic framework for agentic AI systems that can revise their own representational structures during scientific discovery, rather than merely generating answers within fixed assumptions.

Many Logics, One Methodology: A Plea for Logical Pluralism in Formalised Reasoning (preprint)

A academic position paper advocates for logical pluralism in formal reasoning systems, arguing that multiple non-classical logics should coexist within unified meta-logical frameworks like LogiKEy rather than relying on single foundational logics. The research draws from two decades of work embedding diverse logics in classical higher-order logic, positioning logical pluralism as essential for interdisciplinary knowledge representation and reasoning in computational systems.
