opendatalab/ChartVerse-SFT-1800K

ChartVerse-SFT-1800K是一个扩展的大规模图表推理数据集，带有思维链（CoT）注释，是opendatalab/ChartVerse项目的一部分。该数据集包含所有经过验证的正确样本，未经过失败率过滤。与SFT-600K不同，SFT-1800K包括了完整的真实锚定QA对，以实现最大覆盖范围和规模。数据集包含180万QA对，覆盖了多种图表类型，并通过真理锚定的逆向QA合成过程确保答案的正确性。该数据集设计用于最大规模的监督微调（SFT），并包括简单和困难样本以实现全面学习。

ChartVerse-SFT-1800K is an extended large-scale chart reasoning dataset with Chain-of-Thought (CoT) annotations, developed as part of the opendatalab/ChartVerse project. This dataset contains all verified correct samples without failure rate filtering. Unlike SFT-600K which excludes easy samples, SFT-1800K includes the complete set of truth-anchored QA pairs for maximum coverage and scale. The dataset features 1.8M QA pairs, covers diverse chart types, and ensures answer correctness through a truth-anchored inverse QA synthesis process. It is designed for maximum scale SFT (Supervised Fine-Tuning) and includes both easy and hard samples for comprehensive learning.
