Here's how MTPE at Alconost works
Preparation:
During the preparation stage, the project manager (PM) reviews the content and collects additional context if required (e.g., type of content, audience, tone of voice, quality expectations, etc.). In the preparation stage, the PM:
1
Selects a sample from the text (typically ~2000 chars, up to 2 languages) that will be used in engine evaluation.
2
Pre-selects 7-9 Neural Machine Translation (NMT) engines or GenAI for evaluation.
3
(Optional) Conducts prompt engineering if GenAI is used.
4
Sets up a test project on the localization platform.
Evaluation:
The PM performs the following actions to determine which engine(s) perform the best for the given project. There are 2 types of evaluation Express and Deep:
5
Pre-translates the text into all project languages using the pre-selected NMT engine or GenAI. Express Deep
6
Sends the output translation samples to native-speaking human linguists for evaluation. At this stage, the translation outputs generated by each NMT engine or GenAI are reviewed and holistically evaluated. Express Deep
7
Determines the translation sample with the highest evaluation score, which will then be post-edited by human translators. Deep
8
Requests engine scoring. Each translation sample is assigned a score derived based on industry-accepted metrics used to compare sample translations against the post-edited translation (COMET, CHRF, BLEU, hLEPOR, WER). Engines with the highest scores will be used in the project going forward. Based on our experience, NMT/GenAI perform differently for different language pairs and types of content. Deep
9
Based on the holistic evaluation and metrics above (in case of Deep evaluation), the PM prepares the project estimates (budget, turnaround time).
Continuous Translation:
10
The project manager builds the localization workflow, pre-translates content using the NMT/GenAI selected above, allocates tasks to linguists on the localization platform, and monitors deadlines and translation quality.
11
If translators have questions, they ask them on the localization platform. Discussions are visible to the whole project team.
12
The completed translations are automatically exported in the same format as the original files using an API or manually.
13
The PM also conducts recurring QA checks to validate that the output quality is continuously high and that the NMT/GenAI perform as expected. Depending on the project requirements, the NMT/GenAI can be regularly retrained based on glossaries and translation memory accumulated during the project.

MTPE vs Traditional Translation
When deciding between Machine Translation Post-Editing (MTPE) and traditional human translation, several factors come into play. MTPE offers notable advantages over traditional methods:
Cost-Effectiveness:
With less intensive human input when compared to traditional translation, MTPE often leads to lower costs while leveraging advanced machine translation technology.
Scalability:
MTPE scales well for high-volume multilingual projects, quickly providing base translations across various languages for subsequent post-editing.
Consistency:
Machine translation maintains consistency in terminology and style, which is particularly beneficial for large volumes of text, such as in traditional localization. Human editors then refine it to match specific guidelines.
Choose MTPE for projects prioritizing speed, scalability, and cost-effectiveness. Quality is guaranteed by the post-editing process, in which human linguists review content to make sure the quality meets expectations. Traditional translation remains ideal for projects that focus on detailed, high-quality content, demanding deep cultural understanding, like creative and marketing materials and sensitive or confidential documents that require human accuracy and security.
FAQ
How does MTPE work?
MTPE begins with an automated translation which is generated by a machine translation (MT) engine. The raw translation is then sent to a specialist linguist called a post-editor, who reviews and checks the translation for accuracy and consistency. This may involve making corrections or amending the translation in order to make it as accurate and clear as possible.
How do I pick the right MTPE package?
There are several Machine Translation Post-Editing (MTPE) options and it is important to choose the best fit for your business. To simplify your decision-making process, we've outlined 4 key considerations to help you select the most suitable package for your project:
Quality expectations
Raw MT output may or may not meet your requirements for quality. The level of translation quality you need depends on the visibility, level of nuance, and importance of your content. For example, user generated content is neither sensitive nor of critical importance so is a viable candidate for MT + light post-editing. However, website content is of high importance, highly visible, and often has an emotional nuance. The more sensitive to quality the content is, the more advanced MTPE package you'll need to ensure a polished, error-free translation.
Time constraints:
More advanced packages provide more thorough editing that may take more time in comparison to simpler ones.
Complex languages:
Some languages are more viable for MT processes than others because machine translation engines are not yet well-trained enough to accurately translate content into them. This results in the need for more careful post-editing for those language pairs.
Sensitive, highly-branded or nuanced content:
If your content deals with sensitive information, requires a nuanced understanding, or contains humor, then you should consider more advanced packages. It’s this advanced level of post-editing that ensures every translated word aligns perfectly with your original intended message.
Every project is unique, and so are its translation needs. Depending on the project, you may combine different MTPE packages. For instance, you might blend Full MTPE for critical content with RAW MT for support materials. We will work with you to tailor the solution to suit the specific needs of your project.
What is MT Engine Evaluation?
Engine Evaluation is the process of assessing the performance and accuracy of various machine translation engines. It involves testing and analyzing how well the engine translates different content types and evaluating its strengths and weaknesses. This evaluation helps determine the suitability of the engine for specific translation tasks, languages, or content types and allows for optimization or customization to improve translation quality.
Is MTPE more cost-effective than traditional translation services?
MTPE, or Machine Translation Post-Editing, is often more cost-effective than traditional translation services because it combines the speed and efficiency of machine translation with the expertise of human editors. Additionally, MT is quicker, and depending on the level of post-editing required timelines can be substantially condensed. However, it’s important to note that MT is not free: customizing and fine-tuning the engine bears a cost.
What is the difference between Generative AI and Neural Machine Translation (NMT)?
Generative AI (Large Language Models) excels at creating new content by learning from diverse data, ideal for tasks that need innovation and cultural adaptability. NMT, however, is focused on accurately translating text from one language to another and is better suited for industries where precision is critical, like healthcare or law. Regardless of the technology, integrating human oversight can boost translation quality. Choose Generative AI for creative flexibility or NMT for precise translation, based on your project's requirements.
Who are your translators and how are they selected?
All translations at Alconost are performed by professional translators who are native speakers.
We have approximately 700 professional native-speaking translators on our team, who specialize in a broad range of fields. We always try to assign one or more dedicated translators to your project and work specifically with these translators on a continuous basis. This is useful if you have a large project that is updated periodically, you need to use consistent terminology, or you simply like a particular translator's style. If the translator changes for some reason, they will provide the glossary and translation memory to the new translator to ensure consistency of terminology and style in future updates.
What localization TMS (translation management systems or platforms) are you working with?
Our first choice is the cloud-based translation platform Crowdin. It allows us to manage localization projects in real-time. You can:
- Upload string resources in any format (.resx, .po, .strings, etc.) either manually or through the API
- Assign translators and editors
- Track the translation and editing process for your project
- Leave comments and discuss questions directly with the translators and editors
- Create glossaries
- Manage the translation memory
- Export string resources once the translation is complete
We also work on other localization platforms, such as GitLocalize, Phrase, Lokalise, Memsource, memoQ, Smartcat, WebTranslateIt, Transifex, OneSky, POEditor, Trados, and many more.
What file formats do you work with?
We can work with any file type including:
Android .xml, iOS .strings, .stringsdict, Windows .resx, .po, .pot, .php, .json, .ini, .csv, .js, .plist, .xlf, .xliff, .stf, .dita, .ditamap, .toml, .gotext.json, .arb, .vdf, .wxl, .nsh, .properties, .dtd, .ts, .rc, .resw, .resjson, .yml, .htm, .html, .xhtml, .haml, .txt, .md, .xht, .idml, .docx, .svg, .pdf, .xaml, .srt, .vtt, .sbv, .mif, .idml, .rtf, .ppt, .odt, .ods, .odg, .odp, .wiki, .flsnp, .flpgl, .fltoc, .md, .xht.
