# Dataset Card for BioRel

## Dataset Description

- **Repository:** https://drive.google.com/drive/folders/1vw2zIxdSoqT2QALDbRVG6loLsgi2doBG
- **Paper:** [BioRel: towards large-scale biomedical relation extraction](https://bmcbioinformatics.biomedcentral.com/articles/10.1186/s12859-020-03889-5)

#### Dataset Summary

<!-- Provide a quick summary of the dataset. -->
**BioRel Dataset Summary:**

BioRel is a comprehensive dataset designed for biomedical relation extraction, leveraging the vast amount of electronic biomedical literature available. 
Developed using the Unified Medical Language System (UMLS) as a knowledge base and Medline articles as a corpus, BioRel utilizes Metamap for entity identification and linking, and employs distant supervision for relation labeling. 
The training set comprises 534,406 sentences, the validation set includes 218,669 sentences, and the testing set contains 114,515 sentences. 
This dataset supports both deep learning and statistical machine learning methods, providing a robust resource for training and evaluating biomedical relation extraction models.
The original dataset is available here: https://drive.google.com/drive/folders/1vw2zIxdSoqT2QALDbRVG6loLsgi2doBG

We converted the dataset to the OpenNRE format using the following script: https://github.com/GDAMining/gda-extraction/blob/main/convert2opennre/convert_biorel2opennre.py

### Languages

The language in the dataset is English.


## Dataset Structure

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

### Dataset Instances

An example of 'train' looks as follows:
```json
{
  "text": "algal polysaccharide obtained from carrageenin protects 80 to 100 percent of chicken embryos against fatal infections with the lee strain of influenza virus .",
  "relation": "NA",
  "h": {
    "id": "C0032594",
    "name": "polysaccharide",
    "pos": [6, 20]
  },
  "t": {
    "id": "C0007289",
    "name": "carrageenin",
    "pos": [35, 46]
  }
}
```

### Data Fields

- `text`: the text of this example, a `string` feature.
- `h`: head entity
    - `id`: identifier of the head entity, a `string` feature.
    - `pos`: character offsets of the head entity, a list of `int32` features.
    - `name`: head entity text, a `string` feature.
- `t`: tail entity
    - `id`: identifier of the tail entity, a `string` feature.
    - `pos`: character offsets of the tail entity, a list of `int32` features.
    - `name`: tail entity text, a `string` feature.
- `relation`: a class label.
