Unbabel releases High quality Intelligence API to offer entry to award-winning High quality Estimation fashions

We’re releasing an API for accessing AI fashions developed by Unbabel to guage translation high quality. These fashions are broadly established because the state-of-the-art and are behind Unbabel’s profitable submissions to the WMT Shared Duties in 2022 and 2023, outperforming programs from Microsoft, Google and Alibaba. 

Now you can request entry with a view to combine this API into your translation product.

Learn on to find out about: 

  • What’s High quality Estimation (QE) and the way it can influence language operations 
  • How QE fashions get educated and the position of high quality datasets
  • Particular examples of how your corporation can profit from the QI API 
  • What sort of high quality report knowledge you may get utilizing Unbabel’s QI API, supporting excessive degree choices in addition to granular enhancements 
  • The best way to entry and make the most of the API at this time

Computerized translation high quality analysis, often called High quality Estimation (QE), is an AI system that’s educated to establish errors in translation and to measure the standard of any given translation with out human involvement. The perception that QE offers, instantaneously and at scale, permits any enterprise to get transparency into the standard of all their multilingual content material on an ongoing foundation.

Supported with each excessive degree high quality scores and granular translation-by-translation reporting, companies could make broad changes, in addition to surgical enhancements, to their translation method. 

The Unbabel fashions accessed by the API are constructed with our industry-standard COMET expertise, that are persistently acknowledged because the most correct and fine-grained of their class. These Unbabel fashions we offer entry to through the API are of even better accuracy than their state-of-the-art open supply counterparts

How will we ship better accuracy? That is all right down to the Unbabel proprietary knowledge used to coach the mannequin, a results of years of assortment and curation by Unbabel’s skilled annotators. These datasets whole tens of millions of translations overlaying a variety of languages, domains, and content material varieties, and crucially, the info catalogs the myriad methods wherein translations can fail and may succeed.

How can your corporation profit ?

  • You might be using a multi-vendor technique in your translations and want to get visibility into the standard of the varied translation suppliers
  • Your group has an inner group of translators that you simply want to audit for high quality
  • You’ve got developed your personal machine translation programs and want to implement your personal dynamic human-in-the-loop workflow, both in actual time or asynchronously

What knowledge does the API present? 

The High quality Intelligence API offers the person with direct entry to Unbabel’s QE fashions, which give predictions on two ranges:

  1. translation analysis, and; 
  2. error clarification of a selected translation analysis

Translation analysis returns a translation error evaluation following the MQM framework (Multidimensional High quality Metric). The prediction lists the detected errors categorized by severity (minor, main and significant), and summarizes the general translation high quality as a quantity between 0 (worst) and 100 (finest), each at for sentence and at for the entire doc.

Error clarification provides an in depth error-by-error evaluation. It labels the kind of error, identifies the a part of the supply textual content that’s mistranslated, suggests a correction that fixes the mistranslation, and offers clarification of this on the degree of the error, the sentence, and the doc.

Collectively, these predictions present the person with holistic perception into translation high quality, from the very best degree of aggregated MQM scores to the granularity of particular person error evaluation and clarification. It’s this twin reporting that lets customers make excessive degree choices in addition to granular enhancements to make vital enhancements. 

Why does automated high quality analysis matter?

At Unbabel now we have frequently and persistently invested in QE. We consider QE permits accountable use of AI-centric translation at scale, which is the current and way forward for the language {industry}.

Machine Translation (MT) is a strong device, particularly when augmented by context-rich knowledge and complementary algorithms performing language-related duties within the translation course of. Nonetheless, with out visibility into MT high quality, companies won’t ever know if their translations ship worth, and whether or not or the place to spend the time and cash to make enhancements. Till a catastrophic mistranslation reaches the shopper, after all. With QE, there’s no must compromise on high quality, since companies can decide which automated translation wants human correction, and which is sweet as is. We consider that that is accountable use of Machine Translation.

Skilled human translation also can profit from QE. With errors flagged upfront, translators can deal with excellent errors, letting them direct time and a focus to crucial segments as an alternative of enormous swaths of already appropriate translations. This can be a large effectivity improve that human translators can seize at this time. 

API Reporting Examples

A – The person offers a translated doc consisting of three translated segments

B – The person specifies that the interpretation is anticipated to be from Chinese language (Simplified) to English (British) and in a casual register(These instance translations are taken from the check set of the WMT23 QE shared activity.)


A – The general translation high quality of this doc is predicted to be very low. With 4 errors, 2 of that are crucial, the interpretation obtains an MQM rating of 25 out of 100, incomes it the label “weak”

B – Breaking down the analysis per section reveals us that the errors are concentrated within the final two sentences, with the primary sentence deemed to be of excellent high quality

C – The error span annotations listing the errors that decided the analysis rating. The error spans find the error textual content, their severity, and the penalty (weight) that severity incurs. The MQM rating is computed from the sum of those severity weights (1 + 25 + 5 = 31) and is normalized by the variety of phrases (30) following the formulation (1 – 31 / 30) * 100 = -3.33. This formulation additionally applies on the degree of the doc, utilizing the doc whole severity weight and phrase rely.

Clarification endpoint

A – The reason prediction explains – at every degree of the evaluation

B – The prediction additionally offers recommended corrections at every degree of the evaluation

C –  Every error is categorized following an error typology and the a part of supply textual content concerned within the mistranslation is supplied for every recognized error
