PolicyKG: An Agentic LLM Pipeline for Translating Institutional Policies into SHACL Knowledge Graphs

Aug 09, 2026

This work proposes a four-stage pipeline leveraging large language models to automatically translate institutionally authored natural language policies into machine-readable SHACL constraints for automated compliance checking. The approach integrates a LangGraph-based state machine, first-order deontic logic, and a YAML-based vocabulary registry, and introduces a novel plug-in Corpus Adapter mechanism that enables cross-domain transferability by simply swapping the vocabulary registry—eliminating the need for model retraining. Empirical findings reveal that higher-order logical constructs are exceedingly rare in institutional policies; on the AIT corpus, the method achieves 86.9% accuracy (κ = 0.709) in deontic classification and an F1 score of 0.866 for SHACL generation. Switching to a GDPR-specific registry significantly improves attribute alignment (p < 0.001), with fully reproducible results.

From Overload to Convergence: Supporting Multi-Issue Human-AI Negotiation with Bayesian Visualization

Mar 23, 2026

This study addresses the challenge of increased cognitive load in human–agent negotiation as the number of negotiation issues grows, which impairs both performance and autonomy. To mitigate this, the paper proposes the first decision support mechanism that integrates Bayesian estimation of agreement likelihood with interactive uncertainty visualization. Deployed in a residential lease negotiation scenario, the system dynamically visualizes the convergence of mutually acceptable agreement spaces, enabling users to efficiently identify high-potential options. Experimental results from 32 participants demonstrate that the approach significantly improves negotiation outcome quality and efficiency without redistributing bargaining surplus, while effectively preserving human negotiators’ sense of control. These findings underscore the method’s practical utility and novelty in supporting complex, multi-issue human–agent negotiations.
