Structure-Internalized Rule Language Model for Faithful Knowledge Graph Reasoning

The paper introduces the Structure-Internalized Rule Language Model (SIRLM) to improve Knowledge Graph Reasoning (KGR) by addressing the mismatch between KG structural context and Large Language Model (LLM) parametric knowledge. SIRLM centers on a Structure-Internalized Rule Generator (SIRG) that uses in-context learning, a structural relation memory, a KG tokenizer, and a neuro-symbolic reasoner to generate structural rules and provide faithful rule-execution feedback. Experiments on 36 datasets against 17 state‑of‑the‑art KGR methods show that SIRLM achieves significant performance gains.

KGFR: A Foundation Retriever for Generalized Knowledge Graph Question Answering

KGFR introduces a Knowledge Graph Foundation Retriever that collaborates with large language models to enhance knowledge‑intensive question answering. By encoding relations with LLM‑generated descriptions and initializing entities from question roles, KGFR enables zero‑shot generalization to unseen knowledge graphs. Its Asymmetric Progressive Propagation technique efficiently handles large graphs, while a controllable reasoning loop allows the LLM to request candidate answers, supporting facts, and reasoning paths.

Neural Structural Reasoner: A Brain-inspired Architecture for Reasoning over Structured Knowledge

Neural Structural Reasoner (NSR) is a brain-inspired neural network that preserves relational structure directly in the connectivity and dynamics of coupled neuronal populations. It incorporates multi-layered architecture, stable entity representations, and path integration to perform link prediction by parallelizing over candidate relational structures and using confidence-weighted scores. NSR achieves competitive accuracy on knowledge-graph benchmarks, trains faster than several neural baselines, and offers native interpretability by tracking human-readable neuron activations and extracting latent relational hierarchies and compositional rules.
