# MultiCaRe: Open-Source Clinical Case Dataset

MultiCaRe aggregates open-access, de-identified clinical case reports from PubMed Central’s OA corpus, pairing article-level metadata and abstracts with case narratives and figure images/captions. The normalization makes it easy to map from images → cases → articles.

- Source and process: parse PMC OA case reports; extract metadata/abstracts; download/process figures; align captions; build a hierarchical taxonomy for image labels.
- Scale: 85k+ OA articles, 160k+ images (v2.0).
- Tasks: article-level retrieval/classification, summarization; joins to cases/images for multimodal tasks.
- Citation: MDPI DATA paper — <https://www.mdpi.com/2306-5729/10/8/123>; Zenodo — <https://zenodo.org/records/13936721>.

This repository: per-article dataset
Per-article dataset with bibliographic metadata and abstracts (one file: articles.parquet).

Schema

- article_id: PMCID (primary key)
- title, journal, year
- doi, pmid, pmcid
- mesh_terms, major_mesh_terms, keywords
- link, license, case_amount
- abstract: article abstract

Quick start

```python
from datasets import load_dataset
art = load_dataset("openmed-community/multicare-articles", split="train")
row = art[0]
print(row["title"])
print(row["abstract"][:600])
```

Join examples

```python
from datasets import load_dataset
art = load_dataset("openmed-community/multicare-articles", split="train")
cas = load_dataset("openmed-community/multicare-cases", split="train")

aid = cas[0]["article_id"]
article = art.filter(lambda e: e["article_id"] == aid)[0]
print(article["title"])  # matching article
```

Notes

- Use article-level splits to avoid leakage when combining with images/cases.
