### Dataset Summary

A parallel corpus with a subset of 1200 sentence pairs of professional and laymen variants (144 019 tokens), manually simplified by linguists, as a benchmark for medical text simplification. This dataset was collected in the CLARA-MeD project, with the goal of simplifying medical texts in the Spanish language and reducing the language barrier to patient's informed decision making.

### Supported Tasks and Leaderboards

Medical text simplification

### Languages

Spanish

## Dataset Structure

### Data Instances

For each instance, there is a string for the source text (professional version), and a string for the target text (simplified version).

```
{'SOURCE': 'Varones mayores de 18 años, diagnosticados de alopecia androgénica grados I-IV de Sinclair, que no estén realizando ningún tratamiento capilar en la actualidad ni lo hayan realizado en los últimos 3 meses.'
 'TARGET': 'Hombres mayores de 18 años, diagnosticados de alopecia androgénica (calvicie) grados I-IV de Sinclair. Estos hombres no estarán realizando ningún tratamiento para el cabello en la actualidad ni lo habrán realizado en los últimos 3 meses.'}
```

### Data Fields

- `SOURCE`: a string containing the professional version. 
- `TARGET`: a string containing the simplified version. 

## Dataset Creation

### Source Data

#### Who are the source language producers?

Clinical trials announcements from [EudraCT](https://www.clinicaltrialsregister.eu/)

### Annotations

#### Annotation process

Manual simplification technical medical sentences, both at the syntactic and lexical level. Three independent evaluators assessed the quality of the simplification by means of a 5-point Likert scale questionnaires. Human evaluators scored the simplified sentences according to grammar/fluency (average 4.8%), semantic adequacy/meaning coherence (average 4.9%) and overall simplification (average 4.3%). 

#### Who are the annotators?

Rocío Bartolomé-Rodríguez

Leonardo Campillos-Llanos

Ana Rosa Terroba-Reinares
