OCR Benchmark Dataset with Document Images and Text

Ocrbench V2 is a multimodal dataset for evaluating optical character recognition systems, containing images paired with text. The dataset was created by author 'ling99' and uploaded to Hugging Face in February 2025. Platform tags indicate it contains at least 100,000 data points and includes both image and text modalities.

Use Cases

• Benchmarking OCR model accuracy by comparing extracted text from the image modality against the ground truth text modality.
• Training models for multilingual text recognition if the dataset contains text in multiple languages as suggested by its name.
• Evaluating the robustness of OCR systems on varied document layouts and image qualities present in the dataset.
• Fine-tuning pre-trained vision-language models on the specific task of aligning image regions with corresponding text sequences.

Strengths

• Dataset contains at least 100,000 data points as indicated by the '100 K' size tag.
• Data is stored in Parquet format, which is efficient for large-scale data processing.
• Includes both image and text modalities, providing aligned data for model training and evaluation.

Limitations

• Specific column names, data schema, and exact row count are unknown, complicating initial analysis.
• The geographic and temporal coverage of the source documents is unspecified, which may limit generalizability.
• Potential for class imbalance or label noise in the text annotations cannot be assessed without sample data.
