Dataset Summary

• Description: Quarterly reports describing regional economic conditions, sectoral trends, and outlooks in Korea.
• Language: Korean (ko)

Dataset Statistics

• Total documents: 17
• Total corpus pages: 2,780
• Total queries: 351
• Total qrels: 2,066

Page images are not distributed with this dataset. The source documents are published by the Bank of Korea under a copyright policy that does not permit redistribution of the rendered pages, so the corpus config carries an image_path column (a relative path) instead of the page image. Reconstruct the images locally with the included download_images.py, which downloads the original PDFs listed in document_metadata and renders each page to the exact image_path location:

pip install datasets pymupdf requests
huggingface-cli login                          # gated-access token
python download_images.py

Run it from the directory where you load the dataset. Images are written to images/economic_report/<doc_id>/<doc_id>_<page:04d>.png (PyMuPDF, 300 DPI, 1-indexed), matching the image_path column. Then attach them:

from datasets import load_dataset
from PIL import Image

corpus = load_dataset("MarkrAI/korfinvdr-economic_report", "corpus", split="test")
corpus = corpus.map(lambda row: {"image": Image.open(row["image_path"])})

Dataset Structure

1. Corpus

Contains the full collection of documents to be searched.

Data instance of a single item from the corpus subset:

{
  "corpus_id": "<int>",
  "image_path": "<str>",
  "doc_id": "<str>",
  "markdown": "<str>",
  "elements": "<str>",
  "page_number_in_doc": "<int>"
}

• corpus_id <int>: A unique numerical identifier for the corresponding corpus page.
• image_path <str>: Relative path to the page image (images/economic_report/<doc_id>/<doc_id>_<page:04d>.png). The image itself is not shipped; reconstruct it with download_images.py (see the note above).
• doc_id <str>: The identifier of the source document.
• markdown <str>: Text extracted from the page using the document-processing pipeline.
• elements <str>: A JSON-serialized list of extracted layout elements with bounding boxes and text.
• page_number_in_doc <int>: The original page number in the source document.

2. Queries

Contains the set of Korean questions or search queries.

Data instance of a single item from the queries subset:

{
  "query_id": "<int>",
  "query": "<str>",
  "query_type": "<str>",
  "query_format": "<str>",
  "answer": "<str>",
  "evidence_modality": "<str>"
}

• query_id <int>: A unique numerical identifier for the query.
• query <str>: The search question or statement used for retrieval.
• query_type <str>: The category describing the query intent.
• query_format <str>: The query format, such as instruction, keyword, or question.
• answer <str>: The answer grounded in the source documents.
• evidence_modality <str>: The evidence type required to answer the query, rather than the model input format: text, image, or cross-modal.
  • Text (text): Explicit body text, titles, captions, or footnotes are sufficient; no table, chart, figure, or diagram content is required.
  • Image (image): A table, chart, figure, infographic, diagram, map, or visual-layout information alone is necessary and sufficient. Table cells, rows, columns, and merged-cell structure are treated as image evidence.
  • Cross-modal (cross-modal): The answer is supported by both prose text and a table or visual element. The evidence may be complementary or repeated across the two modalities.

3. Qrels

Maps queries to their corresponding relevant corpus pages.

Data instance of a single item from the qrels subset:

{
  "query_id": "<int>",
  "corpus_id": "<int>",
  "score": "<int>"
}

• query_id <int>: A unique numerical identifier for the query.
• corpus_id <int>: A unique numerical identifier for the corresponding corpus page.
• score <int>: The relevance score for the pair <query, corpus>. It can be 1 (Partially Relevant) or 2 (Fully Relevant):
  • Fully Relevant (2): The page contains the complete answer.
  • Partially Relevant (1): The page contains facts required to answer the query, though additional information is required.

4. Document Metadata

Contains document-level metadata for the original PDFs.

Data instance of a single item from the document_metadata subset:

{
  "doc_id": "<str>",
  "title": "<str>",
  "file_name": "<str>",
  "url": "<str>",
  "provider": "<str>",
  "year": "<int>",
  "page_number": "<int>",
  "license": "<str>"
}

• doc_id <str>: The identifier used to associate corpus pages with their source document.
• title <str>: The document title.
• file_name <str>: The original PDF filename.
• url <str>: The source URL for the document.
• provider <str>: The original publisher or provider.
• year <int>: The publication year.
• page_number <int>: The number of pages in the document.
• license <str>: The license or copyright information for the source document.
