# Dataset Card for DocBlocks
DocBlocks is a high-quality, multilingual document-level machine translation (MT) dataset designed to fine-tune large language models (LLMs) on long-context translation tasks. Unlike traditional sentence-level datasets, it contains full documents with natural discourse structures and contextual alignment, helping models maintain coherence, consistency, and high translation quality across longer texts.
- **Curated by:** Instituto Superior Técnico, Instituto de Telecomunicações, Carnegie Mellon University and Unbabel;
- **Language(s) (NLP):** English, German, Spanish, French, Italian, Dutch, Portuguese, Russian, Korean, Chinese;
- **License:** DocBlocks includes data from the following sources: **IWSLT**, **Europarl**, **News Commentary**, **GuoFeng**, and **BWB**. For licensing information, please refer to the official documentation or websites of each source.
### Dataset Details
* `conversations` - The user and assistant dialogue turns, following an instruction-based format suitable for LLM fine-tuning;
* `sources` - The original source text in the source language;
* `references` - The human-translated target/reference text in the target language;
* `language_pair` - The language direction of the translation pair;
* `dataset` - The name of the original dataset from which the document was sourced.
## Bias, Risks, and Limitations
DocBlocks may reflect linguistic, cultural, and domain biases from its source corpora, and its performance is influenced by language coverage and document structure variability.
