# Dataset Card for MedDistant19

## Dataset Description

- **Repository:** https://github.com/suamin/MedDistant19
- **Paper:** https://aclanthology.org/2022.coling-1.198/


#### Dataset Summary

MedDistant19 is a distantly supervised biomedical relation extraction (Bio-DSRE) corpus obtained by aligning the PubMed MEDLINE abstracts from 2019 with the SNOMED-CT knowledge graph (KG) derived from the UMLS Metathesaurus 2019.
For more details, please refer to the paper: https://aclanthology.org/2022.coling-1.198/

**Before Downloading**: To use this data, you must have signed the UMLS agreement. The UMLS agreement requires those who use the UMLS to file a brief report once a year to 
summarize their use of the UMLS. It also requires the acknowledgment that the UMLS contains copyrighted material and that those copyright restrictions be respected. 
The UMLS agreement requires users to agree to obtain agreements for EACH copyrighted source prior to its use within a commercial or production application. See https://www.nlm.nih.gov/databases/umls.html


### 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. -->

### Data Instances

An example of 'train' looks as follows:
```json
{
    "text": "Urethral stones are rarely formed primarily in the urethra and are usually associated with urethral strictures or diverticula .", 
    "h": {"id": "C0041967", "pos": [51, 58], "name": "urethra"}, 
    "t": {"id": "C0041974", "pos": [91, 110], "name": "urethral strictures"}, 
    "relation": "finding_site_of"
}
```

### 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.
