Three "generations"of machine translation
Rules-based machine translation:
Based on
• Linguistic analysis
• Dictionary
Limited usefulness
![Page 5: Neural machine translation: what does it mean for translators? · 2018-03-15 · ‘Neural machine translation: what does it mean for translators?’ March 9th and 10th, 2018 tenvcongres.nl](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4bd2af690fd0165c4d27c6/html5/thumbnails/5.jpg)
Three "generations"of machine translation (contd.)
Data driven engines (statistical and neural)
Data = existing human translations (bilingual corpora)
The machine "learns" from a large number of examples
![Page 6: Neural machine translation: what does it mean for translators? · 2018-03-15 · ‘Neural machine translation: what does it mean for translators?’ March 9th and 10th, 2018 tenvcongres.nl](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4bd2af690fd0165c4d27c6/html5/thumbnails/6.jpg)
Statistical machine translation (SMT)
• Recombines fragments of existing translations based on statistics
• Requires a lot of processing power
• Much better results than the previous (rules-based) systems
![Page 7: Neural machine translation: what does it mean for translators? · 2018-03-15 · ‘Neural machine translation: what does it mean for translators?’ March 9th and 10th, 2018 tenvcongres.nl](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4bd2af690fd0165c4d27c6/html5/thumbnails/7.jpg)
Neural machine translation (NMT)
• Uses neural networks to identify and reproduce patterns of human translations
• Requires even more processing power
• Better, more natural-sounding translations than statistical engines
![Page 8: Neural machine translation: what does it mean for translators? · 2018-03-15 · ‘Neural machine translation: what does it mean for translators?’ March 9th and 10th, 2018 tenvcongres.nl](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4bd2af690fd0165c4d27c6/html5/thumbnails/8.jpg)

Why neural machine translationhas such an impact
• It's noticeably more fluent than previous systems
• To see the flaws, you need to be a translator
• It covers almost all translation needs

Limits of neural machine translation
• Better for some source-target language combinations than others
• Better for "in-domain" translations
• Quality depends on the size of the corpus
• Building engines requires specialists
• Takes time and processing power
• Neural engines are black boxes

Limits of neural machine translation (contd.)
• Translates one sentence at a time – no context beyond the single sentence
• No knowledge of the world

Bij mensen scheiden de bloed-hersenbarrière, de barrière van de bloed-hersenbarrière, de barrière van het bloed-cerebrospinale vocht en soortgelijke vloeistof-hersenbarrières het perifere immuunsysteem van het neuroimmuunsysteem, dat de hersenen beschermt.
In humans, the blood–brain barrier, blood–cerebrospinal fluid barrier, and similar fluid–brain barriers separate the peripheral immune system from the neuroimmune system, which protects the brain.

Using machine translation as a translator
• Beyond post-editing, a wealth of ways to integrate machine translation into the translation process
• Various options, products and services depending on the translation needs
• Be aware of confidentiality issues

Why translators chooseto use machine translation
• Speed
• Typing aid
• Inspiration
• No empty segment
• Dictionary
• Terminology(Study by Dublin City University, 2016)

First neural engines launched in 2017
Used by
• European Commission, European Parliament, Council,other European institutions
• Public administrations across Europe
Both for gisting and as a tool for human translators

eTranslation for translators
• Mix of statistical and neural engines
• Neural first for those languages where statistical engines are less useful: Hungarian, Finnish, Estonian, German
• All other languages (from and into English) will followin 2018 and 2019
• Integrated into the translation workflow, systematically available

eTranslation for translators (contd.)
• Translators free to use machine translation or not
• Translators free to use machine translation snippets or whole sentences
• Widespread adoption
