JSSODa

# JSSODa (train)

[Paper](https://arxiv.org/abs/2511.15059) | [Code](https://github.com/llm-jp/eval_vertical_ja)

This repository contains the **train** and **validation** splits of the JSSODa dataset.

## Dataset details

JSSODa (**J**apanese **S**imple **S**ynthetic **O**CR **Da**taset) is constructed by rendering Japanese text generated by an LLM into images.
The images contain text written both vertically and horizontally, which is organized into one to four columns.

This dataset was introduced in our paper: ["Evaluating Multimodal Large Language Models on Vertically Written Japanese Text"](https://arxiv.org/abs/2511.15059).

The code used to generate this dataset is available at our GitHub repository: [https://github.com/llm-jp/eval_vertical_ja/tree/main/scripts](https://github.com/llm-jp/eval_vertical_ja/tree/main/scripts)

[论文](https://arxiv.org/abs/2511.15059) | [代码](https://github.com/llm-jp/eval_vertical_ja)

本仓库包含JSSODa数据集的**训练集**与**验证集**划分子集。

## 数据集详情
JSSODa（**J**apanese **S**imple **S**ynthetic **O**CR **Da**taset，日语简易合成OCR数据集）是通过将大语言模型（LLM）生成的日语文本渲染为图像构建而成的。生成的图像包含竖排与横排文本，文本以1至4列的形式排布。

本数据集出自我们的论文：《针对竖排日语文本的多模态大语言模型评测》(https://arxiv.org/abs/2511.15059)。

本数据集的生成代码可在我们的GitHub仓库中获取：[https://github.com/llm-jp/eval_vertical_ja/tree/main/scripts](https://github.com/llm-jp/eval_vertical_ja/tree/main/scripts)
