UV_PARALLEL_VA_ES Dataset

Dataset Summary

UV_PARALLEL_VA_ES is a parallel dataset for machine translation between Valencian (VA) and Spanish (ES).
It consists of aligned sentence pairs along with the source file from which each pair was extracted.
The dataset is intended for research in machine translation, cross-lingual NLP, and linguistic analysis.

Dataset Structure

Each row in the dataset includes the following fields:

• VA: A sentence in Valencian.
• ES: The corresponding Spanish sentence.
• Source: The file from which the parallel sentence pair was obtained.

Dataset Creation

Curation Rationale

This dataset is aimed at promoting the development of Machine Translation between Valencian and Spanish, supporting research in multilingual NLP and facilitating the development of translation systems for these language pairs.

Source Data

The parallel data in this dataset is extracted from web news published by the Universitat de València (UV). All sentence pairs originate from publicly available articles on the university's official communication channels.

Data Filtering and Normalization

All data underwent rigorous filtering and normalization:

• Alignment filtering: Sentence- and paragraph-level alignments were calculated with the gplsi translation-alignment tool.
• Language identification: Valencian documents are filtered using a private discriminative tool to differentiate them from Catalan.
• Deduplication: The filtered datasets were deduplicated to remove redundant sentence pairs

The filtered and normalized datasets were then concatenated to form the final corpus.

Funding

This dataset is funded by the Ministerio para la Transformación Digital y de la Función Pública — Funded by EU – NextGenerationEU, within the framework of the project Desarrollo de Modelos ALIA.
