ERA-CoT: Enhancing Chain-of-Thought through Entity Relationship Analysis This paper proposes ERA-CoT, a novel framework to improve the reasoning ability of large language models (LLMs) by analyzing entity relationships in complex scenarios. The method involves five stages: entity extraction, explicit relationship extraction, implicit relationship inference, relationship discrimination, and question answering. ERA-CoT enhances the LLM's understanding of entity relationships, leading to improved accuracy in question answering and reasoning tasks. The framework first extracts all entities from the text and identifies explicit relationships between them. It then infers implicit relationships based on the explicit ones and the context. Relationships are scored based on their reliability, and those below a threshold are discarded. Finally, the model answers the question using the extracted entities and relationships. Experiments on six datasets show that ERA-CoT outperforms existing CoT methods, achieving an average improvement of 5.1% on GPT3.5. The method performs well on commonsense, logical, and mathematical reasoning tasks, demonstrating its effectiveness in enhancing LLM reasoning and accuracy. ERA-CoT combines chain-of-thought reasoning with relation extraction, enabling the model to infer complex relationships and perform accurate logical analysis. It is effective for tasks involving multiple entities and complex relationships, and shows strong performance on both GPT3.5 and Llama-2. The method also includes self-consistency checks to ensure the reliability of extracted relationships, improving the model's accuracy and consistency. It is particularly effective in scenarios with complex relationships and can handle a wide range of tasks. The paper also includes ablation studies and error analysis, showing that ERA-CoT improves model performance by enhancing entity relationship understanding. It is effective in both high and low relationship density scenarios, and performs well on datasets with limited relationships. Overall, ERA-CoT enhances the reasoning ability of LLMs by analyzing entity relationships, leading to improved performance in various reasoning tasks. The method is versatile and can be applied to a wide range of tasks and models.ERA-CoT: Enhancing Chain-of-Thought through Entity Relationship Analysis This paper proposes ERA-CoT, a novel framework to improve the reasoning ability of large language models (LLMs) by analyzing entity relationships in complex scenarios.
