Machine Translation
Also known as: MT, neural machine translation, automatic translation, Makine Çevirisi (Machine Translation)
Machine translation (MT) is a natural-language-processing task that automatically converts text in one language into another. Modern MT is built on neural sequence-to-sequence models — the attention mechanism introduced by Bahdanau et al. (2015) and the transformer architecture of Vaswani et al. (2017) — and it widens access to sources for multilingual data analysis and research.
Key highlights
- Widens access to sources by making text in other languages usable for analysis and research.
- Neural attention and transformer models translate whole sentences in context rather than word by word.
- Scales from short passages to large multilingual corpora through the same model.

When to use it
Use machine translation when you have source-language text and need it in another language, and a trained model for that language pair is available. It suits widening source access in multilingual data analysis and research. For specialised-domain text, expect to fine-tune the model. At least a small amount of text is needed to translate.
Strengths & limitations
- Widens access to sources by making text in other languages usable for analysis and research.
- Neural attention and transformer models translate whole sentences in context rather than word by word.
- Scales from short passages to large multilingual corpora through the same model.
- Requires an available trained model for the specific source and target language pair.
- Specialised-domain translation may need fine-tuning before it is accurate enough.
- Output must still be checked for fidelity and fluency; errors can be subtle.

Frequently asked
What kind of model does machine translation use?
Modern MT uses neural sequence-to-sequence models. The attention mechanism (Bahdanau et al., 2015) lets the model align source and target as it translates, and the transformer architecture (Vaswani et al., 2017), built entirely on attention, underpins current systems.
Do I need a model for my specific language pair?
Yes. A trained model for the source and target language pair must be available. Without coverage for that pair, the system cannot produce usable translations.
Why might translation quality be poor on my texts?
Specialised-domain material often needs fine-tuning. A general model may translate everyday language well but struggle with domain-specific terminology until it is adapted on in-domain text.
Should I trust the output directly?
Check it. Translated output should be evaluated for fidelity to the source and fluency in the target language before it feeds into further analysis, since errors can be subtle.
