Dataset Summary

This dataset provides a convenient access to the processed main and pretask splits of the QE4PE dataset. A sample of challenging documents extracted from WMT23 evaluation data were machine translated from English to Italian and Dutch using NLLB 3.3B, and post-edited by 12 translators per direction across 4 highlighting modalities employing various word-level quality estimation (QE) strategies to present translators with potential errors during the editing. Additional details are provided in the main task readme and in our paper. During the post-editing, behavioral data (keystrokes, pauses and editing times) were collected using the GroTE online platform.

We publicly release the granular editing logs alongside the processed dataset to foster new research on the usability of word-level QE strategies in modern post-editing workflows.

News 📢

October 2024: The QE4PE dataset is released on the HuggingFace Hub! 🎉

The language data of QE4PE is in English (BCP-47 en), Italian (BCP-47 it) and Dutch (BCP-47 nl).

Dataset Structure

Data Instances

The dataset contains two configurations, corresponding to the two tasks: main and pretask. main contains the full data collected during the main task and analyzed during our experiments. pretask contains the data collected in the initial verification phase, before the main task begins.

Train Split

The train split contains the totality of triplets (or pairs, when translation from scratch is performed) annotated with behavioral data produced during the translation.

The following is an example of the subject oracle_t1 post-editing for segment 3 of doc20 in the eng-nld direction of the main task. The fields mt_pe_word_aligned and mt_pe_char_aligned are shown over three lines to provide a visual understanding of their contents.

Dataset Creation

The datasets were parsed from GroTE inputs, logs and outputs for the QE4PE study, available in this repository. Processed dataframes using the qe4pe process_task_data command. Refer to the QE4PE Github repository for additional details. The overall structure and processing of the dataset were inspired by the DivEMT dataset.
