Comparing Four Machine Translation Deployment Strategies

Machine Translation (MT) has been around for decades. In recent years, it has evolved at an exponential rate. As companies produce ever-growing amounts of content in different languages, they have come to see MT as an opportunity to extend their reach in an increasingly globalized world. 

Companies seeking to deploy MT can explore the following four basic strategies. 

Public MT

This strategy includes services like Google Translator or Bing Translate. Such services are readily available at no cost. However, the engines are completely unsecure and not trained for specific domains or particular use cases. 

On-Premise MT

This strategy requires a company to deploy an MT server in its own IT environment. While this is the most secure option, it comes at a significant cost, is complex to deploy and manage, and requires ongoing maintenance. Importantly, this strategy often produces suboptimal MT output across multiple language pairs or content types.

Cloud MT

This strategy works like Public MT, is also hosted in the cloud, but creates a company-dedicated instance. Any data shared with the service is tightly secured and not shared with third parties. It provides additional capabilities around terminology customization and has other benefits. However, it can result in vendor lock-in and less-than-optimal MT quality across multiple language pairs.

Best of Breed MT

This is a single platform that allows companies to leverage multiple MT engines. It provides a single layer of terminology customization, an easy-to-manage interface and the ability to choose the best engines for different language pairs, industries or domains, and types of content. 

No matter which strategy you are contemplating, selecting the right engine may be challenging without the proper data and MT experience. Lionbridge is an expert in MT. In addition to having more than two decades of MT experience, we have gathered a large volume of linguistic and quality data about MT technology that will help you make the right choice. This webpage provides basic information about the performance of popular MT engines for the most common language pairs to help you select the best option based on your content. 

 

Which Machine Translation (MT) engine is best? There’s no simple answer.


When choosing among the many available MT systems, it’s important to note some engines address a specific function or domain. If your needs don’t align with that purpose, the engine may perform sub-optimally no matter how advanced it is. To determine the best option, first, identify why you are using MT.

If you want an MT engine for general use, it may be appropriate to use Google Translate or Bing Translator. If you seek MT services for a specific language or domain, you may achieve better results by turning to Amazon Translate or DeepL Translator.

Lionbridge’s Machine Translation Tracker analyzes engine performance monthly to help you figure out the best MT engine depending on the language pairs you use. The next time you ask which MT engine is best, reframe the question to, “Which MT engine is best for me?” And count on Lionbridge for guidance.

Lionbridge Expert's Commentary

August 2022

As companies increasingly rely on Machine Translation (MT) as a standard practice, employees will need to prevent the dissemination of catastrophic errors.

Catastrophic errors are more problematic than standard MT errors, which pertain to error typology related to linguistic features, such as spelling, grammar, or punctuation. Catastrophic errors transcend linguistics and occur when engine output dangerously deviates from the intended message. Resulting misinformation or misunderstandings have the potential to cause companies reputational, financial, or legal problems and may lead to adverse public safety or health consequences. It is essential to find ways to identify these errors and stop them from compromising your communications.

Lionbridge administers specific automated quality checks in translated texts to detect critical errors while preserving MT speed and reducing the need for human intervention.

These automated methods detect:

  • Opposite meanings between original and translated texts
  • Offensive, profane, or highly sensitive words
  • Incorrect translations of proper names of individuals and organizations that are also common words

Companies will be better protected from catastrophic errors when computer scientists improve existing MT technology to prevent these translation errors. Until such time, we can use automated technology to identify potential issues, revise problematic sentences, and promote accuracy during the translation process.

Lionbridge Machine Translation Tracker Methodology

Lionbridge uses inverse edit distance as a scoring method. The edit distance measures the number of characters (for Asian languages) or words (for Western languages) that need to be changed by a human post-editor before it achieves the quality level produced by a human translator. The higher the metric, the better the quality.

Out of the four MT engines we assessed, Google and Bing NMT performed best across different language pairs and for general content. However, specialized engines performed best for certain language combinations. For instance, DeepL had the strongest performance in German, and Amazon translated Chinese best.
