### Dataset Summary
This dataset card aims to be a base template for new datasets. It has been generated using [this raw template](https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/templates/datasetcard_template.md?plain=1).
### Supported Tasks and Leaderboards
Natural Language Inference.
### Language
English
## Dataset Structure
### Data Instances
Each instance of the dataset has the following fields and the following types of fields.
```json
{
"id": "621",
"topic_id": "2",
"statement_medical": "A 32-year-old woman comes to the hospital with vaginal spotting. Her last menstrual period was 10 weeks ago. She has regular menses lasting for 6 days and repeating every 29 days. Medical history is significant for appendectomy and several complicated UTIs. She has multiple male partners, and she is inconsistent with using barrier contraceptives. Vital signs are normal. Serum \u03b2-hCG level is 1800 mIU/mL, and a repeat level after 2 days shows an abnormal rise to 2100 mIU/mL. Pelvic ultrasound reveals a thin endometrium with no gestational sac in the uterus.",
"statement_pol": "I just turned 32 and last morning I woke up with strange blood stains on my underwear. My last periods were more than 2 months ago, which is unusual for me because I used to have regular periods lasting for 6 days every 29 days, more or less. I had several UTIs in the past. I also had appendicitis. I'm currently seeing several men and, to be honest, some of them do struggle to wear a condom. I went to the hospital to check myself up and they told me that my vitals were normal. I also had a blood test on Monday, and my \u03b2-hCG level was 1800 mIU/mL, and then on Wednesday, it went up to 2100 mIU/mL. The gynecologist also did an ultrasound and she told me that, hopefully, there was no ovule.",
"premise": "Inclusion Criteria:\n\n - women with PUL\n\n Exclusion Criteria:\nFemale\nAccepts Healthy Volunteers\n\n",
"NCT_title": "Hysteroscopy for Pregnancy of Unknown Location",
"NCT_id": "NCT02637739",
"label": "Entailment"
}
```
### Data Fields
Each instance has the following fields: **id**, **topic_id**, **statement_medical**, **statement_pol**, **premise**, **NCT_title**, **NCT_id**, **label**.
### Data Splits
Train: 4904 instances
Validation: 525 instances
Test: 1578 instances
## Dataset Creation
### Source Data
#### Initial Data Collection and Normalization
_premise_ (CTRs) and *statement_medical* taken from TREC-CT 2022.
### Annotations
#### Annotation process
Automatic mapping of TREC-CT 2022's ranking to NLI annotations. _eligible_ mapped as _Entailment_ and _excluded_ mapped as _Contradiction_.
Manual rephrasing of original *statement_medical*
### Annotators
Paper's first author.
### Dataset statistics
|Split|# Entailment| # Contradiction |
