Living in the Moment: Can Large Language Models Grasp Co-Temporal Reasoning?
This addresses a limitation in LLMs' ability to handle realistic concurrent events for AI applications requiring temporal understanding, though it is incremental as it focuses on benchmarking and preliminary exploration.
The authors tackled the problem of large language models (LLMs) lacking co-temporal reasoning by introducing CoTempQA, a benchmark with 4,748 samples across four scenarios, revealing a significant performance gap between LLMs and human-level reasoning, even with Chain of Thought enhancements.
Temporal reasoning is fundamental for large language models (LLMs) to comprehend the world. Current temporal reasoning datasets are limited to questions about single or isolated events, falling short in mirroring the realistic temporal characteristics involving concurrent nature and intricate temporal interconnections. In this paper, we introduce CoTempQA, a comprehensive co-temporal Question Answering (QA) benchmark containing four co-temporal scenarios (Equal, Overlap, During, Mix) with 4,748 samples for evaluating the co-temporal comprehension and reasoning abilities of LLMs. Our extensive experiments reveal a significant gap between the performance of current LLMs and human-level reasoning on CoTempQA tasks. Even when enhanced with Chain of Thought (CoT) methodologies, models consistently struggle with our task. In our preliminary exploration, we discovered that mathematical reasoning plays a significant role in handling co-temporal events and proposed a strategy to boost LLMs' co-temporal reasoning from a mathematical perspective. We hope that our CoTempQA datasets will encourage further advancements in improving the co-temporal reasoning capabilities of LLMs. Our code is available at https://github.com/zhaochen0110/Cotempqa.
