# Lit2Vec TL;DR Chemistry Dataset

## Summary

The **Lit2Vec TL;DR Chemistry Dataset** is a curated collection of **19,992 chemistry research abstracts** paired with **short, TL;DR-style abstractive summaries**.  
It was created to support research in **scientific text summarization**, **semantic indexing**, and **domain-specific knowledge graph construction**.

Unlike generic summarization datasets, this corpus is:

- **Legally reusable** → all abstracts are sourced from **CC-BY licensed publications**  
- **Domain-specific** → chemistry and closely related fields (materials science, chemical engineering, environmental science, etc.)  
- **Schema-consistent** → each summary follows a concise “methods–results–significance” style

## Usage

```python
from datasets import load_dataset

DATASET_ID = "Bocklitz-Lab/lit2vec-tldr-bart-dataset"

# Prefer the modern `token=` param; fall back to use_auth_token if your version needs it.
try:
    ds = load_dataset(
        DATASET_ID,
        split=None,                # get all splits if defined
        token=True,                # uses your cached HF login
        revision="main",           # avoid refs/convert/parquet unless we ask for it
        cache_dir="./.hf_cache_fresh",
        download_mode="force_redownload",
    )
except TypeError:
    # Older versions
    ds = load_dataset(
        DATASET_ID,
        split=None,
        use_auth_token=True,
        revision="main",
        cache_dir="./.hf_cache_fresh",
        download_mode="force_redownload",
    )

print(ds)
print(ds["train"][0]["abstract"])
print(ds["train"][0]["summary"])
```

## Applications

* **Abstractive summarization training** (BART, DistilBART, T5, LLaMA fine-tuning)
* **Information retrieval** in chemistry and materials science
* **Knowledge graph population** from structured summaries
* **Domain-specific semantic search engines**

---

## Licensing

* All abstracts are sourced from **CC BY 4.0 licensed publications**.
* Summaries are **machine-generated** and also distributed under **CC BY 4.0**.
* Attribution information (publisher, OA URL, DOI) is included in the metadata for each record.
