📖Paper |🏠Homepage|🤗Huggingface

The automatic understanding of lengthy documents (Long-context Document Understanding; DU) stands as a long-standing task in urgent and practical needs. Although many LVLMs now claim (and show promising cases) their capabilities on long-context DU, there lacks a unified and quantitative evaluation of existing models due to the absence of related benchmark.
To bridge this gap, we construct MMLongBench-Doc which comprises 135 documents and 1091 qustions (each accompanied by a short, deterministic reference answer and detailed meta information.). The documents have an average of 47.5 pages and 21,214 tokens, cover 7 diverse domains, and are PDF-formatted with rich layouts and multi-modal components. The questions are either curated from existing datasets or newly-annotated by expert-level annotators. Towards a comprehensive evaluation, the questions cover different sources like text, table, chart, image, etc., and different locations (page index) of the documents. Notably, 33.0% questions are cross-page questions necessitating comprehension and reasoning on evidences across multiple pages. And 22.5% questions are designed to be unanswerable for reducing the shortcuts in this benchmark and detecting LVLMs' hallucinations.

📢 News

  • 🚀 [07/2024] We have integrated MMLongBench-Doc to evaluation toolkit VLMEvalKit, providing a highly convenient testing solution!
  • 🚀 [06/2024] We upload MMLongBench-Doc to huggingface.

💡 Highlights

  • 🔥 Multi-modality: All selected documents are PDF-formatted with rich layouts and multi-modal components including text, table, chart and image. We annotate questions carefully from these multi-modal evidences.
  • 🔥 Long-context: Each document has an average of 47.5 pages and 21,214 tokens. Additionally, 33.0% of the questions are cross-page questions which necessitate the information collection and reasoning over multiple pages.
  • 🔥 Challenging: Experiments on 14 LVLMs demonstrate that long-context document understanding greatly challenges current models. Even the best-performing LVLM, GPT-4o, achieves an overall F1 score of only 44.9%.

Dataset

We save our benchmark, including both questions and documents, in ./data.

  • The questions are provided in json format and contain the following attributes:
    {
        "doc_id": "Independents-Report.pdf",
        "doc_type": "Research report / Introduction",
        "question": "What's the percentage of people who are democrats and voted in the last election compared to the entire population in 2018?",
        "answer": "18.29%",
        "evidence_pages": "[3, 5]",
        "evidence_sources": "['Pure-text (Plain-text)']",
        "answer_format": "Float",
    }
  • The documents are saved in ./data/documents as the format of PDF files.

You can also download this dataset by the following command (make sure that you have installed Huggingface Datasets):

from datasets import load_dataset
samples = load_dataset("yubo2333/MMLongBench-Doc/data")["train"]

🛠️ Usage

Environment

python 3.9
2.1.2+cu121

You can install other dependencies by pip install -r requirements.txt.

Quick Use

MODEL_NAME=[gpt-4o|gpt-4-turbo|gemini-1.5-pro-latest|internvl|4khd|minicpm_llama3] bash run.sh

Note that

  • OPENAI_API_KEY should be set no matter what models you are evaluating because we adopt a three-stage evaluation protocol as detailed in Section 4.1 of our paper. The conversion from a long-form response to a short-form prediction necessitates GPT-4o's involving.
  • We now support various popular open-source and closed-source LVLMs, including GPT-4o, GPT-4V, Gemini-Pro-1.5,InternLM-Xcomposer2-4KHD, Intern-VL-Chat-v1.5 and MiniCPM-Llama3-V2.5. More LVLMs will be supported in the near future (we are cleaning related code).
