About this paper

Hong Qing Yu

This paper presents T-CPDL, a novel integrated logical framework combining temporal, causal, and probabilistic reasoning within a decidable Description Logic. It demonstrates that LLMs can effectively extract structured knowledge into T-CPDL, enhancing their ability to perform robust and transparent reasoning by grounding their outputs in a verifiable logical substrate.

Key insights

• Integrating temporal, causal, and probabilistic reasoning within a single decidable Description Logic provides a unified framework for representing and reasoning about complex, dynamic knowledge.
• Large Language Models (LLMs) can be effectively prompted to extract structured logical knowledge in T-CPDL format from unstructured natural language, bridging the gap between symbolic and statistical AI.
• The proposed T-CPDL maintains strong theoretical properties, including decidability (EXPTIME-completeness) and tableau soundness and completeness, ensuring its practical applicability for automated reasoning.
