### Dataset Structure

#### Data Fields

<!-- info: List and describe the fields present in the dataset. -->
<!-- scope: telescope -->
Each sample comes with the following fields:

- `gem_id` (string): Unique sample ID
-`text` (string): The raw text to be simplified
-`simplified_text` (string): The simplified version of "text" field
-`transformation_type` (string): Nature of transformation applied to raw text in order to simplify it.
-`source_dataset` (string): Initial dataset source of sample. Values: 'itwiki' (for Italian Wikipedia) or 'tn' (manually annotated administrative documents from the Municipality of Trento, Italy)

#### Reason for Structure

<!-- info: How was the dataset structure determined? -->
<!-- scope: microscope -->
