NeSTR: A Neuro-Symbolic Abductive Framework for Temporal Reasoning in Large Language Models
Large Language Models (LLMs) excel in many NLP tasks but struggle with complex temporal reasoning. NeSTR addresses this by integrating structured symbolic representations with hybrid reflective reasoning. This novel framework enhances LLM temporal sensitivity through symbolic encoding, logical consistency verification, and abductive reflection, achieving superior zero-shot performance on diverse temporal Question Answering (QA) benchmarks without requiring fine-tuning.
Key Metrics & Strategic Impact
This research provides a critical framework for enhancing AI's ability to understand and reason with time-sensitive information, crucial for enterprise applications requiring precise temporal understanding in dynamic contexts like financial forecasting, supply chain optimization, and compliance.

Symbolic structuring involves converting raw temporal information from natural language into explicit, structured forms, such as logical predicates. This approach provides a transparent and interpretable basis for rule-based reasoning, making temporal facts visible and tractable. It helps ensure consistency and reduces ambiguity inherent in natural language expressions of time.
Reflective reasoning leverages the inherent flexibility of Large Language Models to revise initial inferences through multi-step processes. By prompting LLMs to reflect on intermediate steps, models can identify and correct reasoning errors, enhancing overall consistency and accuracy, especially in complex or unfamiliar temporal tasks.
Neuro-symbolic integration combines the precision of symbolic logic with the adaptability and generalization capabilities of neural models. NeSTR achieves this by performing flexible multi-step inference directly over structured symbolic representations, enabling consistency checking, pattern recognition, and abductive reflection to revise conclusions when inconsistencies are detected.

Ablation Study: NeSTR Component Contribution
The ablation study demonstrates that each component of NeSTR (symbolic representation, consistency verification, and abductive reflection) critically contributes to its overall accuracy. Removing any single component significantly degrades performance on complex temporal reasoning tasks, underscoring the benefits of a fully integrated neuro-symbolic approach. For instance, the 'w/o Symbol' variant showed a notable drop in F1 score on TimeQA-Hard from 81.7 to 74.2, emphasizing the necessity of structured temporal representations. The 'w/o Consistency Check' also led to degradation (81.7 to 77.3 on TimeQA-Hard), validating the need for logical validation.
