Dataset Structure

Data Fields

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

The dataset is organized as a pairs where the raw text (input) is associated with its simplified text (output). The editing transformation and the source dataset of each sample is also provided for advanced analysis.

How were labels chosen?

SIMPITIKI dataset selects documents from Italian Wikipedia such that their editing tracking descriptions contain any of the words "Simplified"/"Simplify"/"Simplification". For the Public Administration domain of the documents of the Municipality of Trento (Italy)

Example Instance

{"transformation_id": 31, "transformation_type": "Transformation - Lexical Substitution (word level)", "source_dataset": "tn", "text": "- assenza per <del>e</del>si<del>genze</del> particolari attestate da relazione dei servizi sociali;", "simplified_text": "- assenza per <ins>bi</ins>s<ins>ogn</ins>i particolari attestati da relazione dei servizi sociali;"}

Data Splits

Several splits are proposed to train models on different configurations:

-"train": Training samples randomly selected from initial corpus. 816 training samples. -"validation": Validating samples randomly selected from initial corpus. 174 validating samples. -"test": Testing samples randomly selected from initial corpus. 176 validating samples. -"challenge_seen_transformations_train": This training challenge split includes specific transformations to simplify the raw text.

Splitting Criteria

The training ratio is set to 0.7. The validation and test somehow equally divide the remaining 30% of the dataset.

Split Motivation

The splits allows to investigate the generalization of models regarding editing/transformations ("challenge_seen_transformations_test" / "challenge_unseen_transformations_test") and for transfer learning to different domain ("challenge_tn_test")

Dataset Curation

Original Curation

Original Curation Rationale

Most of the resources for Text Simplification are in English. To stimulate research to different languages, SIMPITIKI proposes an Italian corpus with Complex-Simple sentence pairs.

Communicative Goal

Text simplification allows a smooth reading of text to enhance understanding.
