## Dataset Description

This dataset contains a high-quality, real (non-synthetic) parallel corpus in the **scientific and academic domain**, covering **Basque (eu), Spanish (es), and English (en)**. 

Unlike synthetically generated datasets, this corpus is built from genuine, human-authored trilingual abstracts extracted from **ADDI** (*Archivo Digital de Docencia e Investigación*), the institutional digital repository of the University of the Basque Country (UPV/EHU). It is specifically designed to support the training, fine-tuning, and evaluation of Machine Translation systems and Large Language Models (LLMs) for specialized scientific text.

## Source Data

The raw documents were scraped and curated from multiple academic collections within the ADDI repository. The texts are predominantly published under Creative Commons licenses.

**Document Types Included:**
* Doctoral Theses
* Master's Theses (Trabajos de Fin de Máster)
* Bachelor's Theses (Trabajos de Fin de Grado)
* Academic Journals and Journal Articles

**Metadata Included:**
Each parallel record in the dataset is accompanied by rich metadata to facilitate targeted filtering. *(Note: To ensure privacy, author and supervisor names have been explicitly anonymized).*
* **Publication Date**
* **Submission Date**
* **URI** (Original source link)
* **Language** (The main language of the full publication)
* **License**
* **Title**
* **Department**

The dataset consists of **3,294 perfectly aligned trilingual documents** (yielding 3,294 tuples of Basque, Spanish, and English). 

| Metric | Basque (EU) | Spanish (ES) | English (EN) |
|---|---|---|---|
| **Total Documents** | 3,294 | 3,294 | 3,294 |


*(Note: The lower average word count in Basque compared to Spanish and English, despite similar character counts, reflects the agglutinative morphological nature of the Basque language).*
