Custom Machine Translation Engines

Customize your own high-quality MT engine for writing style, vocabulary and domain.

Human Language Technology Enhanced by Artificial Intelligence

Creating a custom machine translation engine is an art. While rapid customization can be performed by uploading data to train an engine, this approach is best suited to engine improvements to an existing high-quality machine translation engine. A high-quality machine translation engine comes from a deep understanding of the data, the goals/purpose of use, and a strategic approach to creating and applying the correct data to obtain optimal machine translation quality.

Anyone can create a custom MT engine. But it takes experience and expertise to create a great custom MT engine that is optimized for purpose. Much like in a kitchen, just throwing ingredients in a pot does not make a great meal. A good recipe, a skilled chief, and the right tools will give a much better result.

The key to creating a high-quality machine translation engine is a combination of the right data to train an engine and pre-/post-processing that are optimized for your specific purpose. 

With over 14 years of experience creating tens-of-thousands of custom machine translation engines, the Omniscien team has refined a methodology and set of powerful tools that together provide unmatched translation quality. Many of the tools and processes are unique to Omniscien and are designed to make it fast and easy to create your own custom machine translation engines.

Omniscien experts fully understand the Anatomy of a Great Custom Machine Translation Engine and work with you to quickly organize and create the data needed to build a high-quality machine translation engine that is optimized to match your specific requirements. 

Language Studio offers 2 types of custom machine translation engines training. The Standard Custom MT Engine option provides a do-it-yourself approach that allows you to upload your data and simply click the “Train” button. However, while you can use this approach to customize your own MT engine, it is more suited to updating an existing engine that has been professionally customized. We recommend that the initial customization be performed using Language Studio’s Professional Guided Custom MT Engine option to ensure the highest possible quality.

Writing Style

In addition to customizing for domain and context, one of the major benefits of a Professional Guided MT Engine is the ability to influence writing style.

In the diagram, a Spanish sentence is translated using two different machine translation engines. The first was customized for English Business and reads more like the Economist or Forbes style of writing. The second was customized for English Children’s Books and reads more like Harry Potter.

This example shows the true impact of taking into account writing style. If the writing style does not match purpose, then the content must be rewritten – even if the translation was perfectly correct.  Applying this to a more real-world scenario, Automotive is a broad and complex domain with an extensive amount of terminology and domain-specific vocabulary. But a different writing style is needed for Automotive marketing than would be used in an Automotive Engineering Technical Manual.

Anatomy of a Great Custom MT Engine

5 years ago, a typical custom machine translation engine was based on between 2-to-4 million generic bilingual sentences and between 100-to-500 thousand domain-specific sentences provided by the user/client. At that time, it was already a challenge for many organizations to gather that many bilingual translation memory sentences. If you did not have any of your own data, finding suitable data to customize a machine translation engine was a significant barrier to building your own custom machine translation engine.

With the advent of Neural Machine Translation the volume of data required has multiplied many times over. Today’s typical custom machine translation engines are based on between 50-to-300 million bilingual sentences. This is comprised of about 80% general language pair foundation data that acts as a base underpinning the engine for grammar, vocabulary, and core linguistic knowledge that trains the artificial intelligence algorithms on how to better understand relationships between words and phrases. A further 20% is based on industry domain data such as life sciences, information technology or automotive that teaches the engine a specific context.

Language Studio provides powerful tools to create, match, mine and synthesize bilingual sentences that are specific to your context, domain, and purpose. A rapid customization can be performed with your own data with some reasonable translation quality improvement. Comparatively, with the additional data created by Language Studio tools, translation quality is taken to the next level.

The role of user/client data plays a different role than in the past. Depending on the volume of data available, it can be used as a base from which to synthesize considerably larger amounts of data. It is often possible to create as much as 10 times the volume of data through various forms of data synthesis. In domain monolingual data also provides an important base for vocabulary and terminology that can be useful in building a bilingual glossary and for data synthesis.

Bilingual data mining creates a larger set of domain specific data from external sources that further expands vocabulary choice, writing style and domain specific context. The combination of all these tools working together and driven by guidance from the client produces millions of high-quality in domain and context relevant bilingual sentences.

With a Professional Guided Custom Machine Translation Engine, an Omniscien expert with tailor an Engine Customization Plan to your specific needs. User/client involvement is minimized with most activities handled by the Omniscien team and automated tools.

Powerful Tools for Data Creation, Preparation, and Analysis

Convert legacy files into “data gold” and create new high-quality bilingual data quickly and efficiently.

In the process of building thousands of custom machine translation engines for clients the Omniscien team found many manual tasks to be repetitive and often too large and too error-prone to be performed with humans alone. Over many years a large number of internal tools were developed to help automate these processes and improve data quality. With the release of Language Studio V6.0 these tools are now available as part of the standard Language Studio platform.

Custom MT Engines

Extract and Create Bilingual Glossaries and Terminology

Language Studio can import and process industry standard glossary formats such as TBX. To extend a TBX or create a new glossary can take a considerable amount of time. To quickly create your own bilingual glossaries Language Studio provides a comprehensive set of tools that set and resolve bilingual glossary terms. Glossaries can be used as training data for custom machine translation engines or as runtime rules when processing a translation.

Reduce the time to create a glossary for a body of text from hours to minutes. Language professionals can quickly validate and fine-tuning the automated results. When creating bilingual glossaries, language professionals need only check and adjust suggested glossary phrases, increasing their productivity from an average of 20 to more than 160 terms per hour.

Create and Match Bilingual Data

Turn your legacy language data assets into “data gold”. Many organizations and Language Service Providers (LSPs) have large numbers (sometimes even tens of thousands of files) that have been built using multiple platforms and with sometimes non-optimal management controls and filing systems.

Simply upload files and automatically identify and match their bilingual document pairs and extract high-quality bilingual sentences. Even monolingual data can be leveraged as a driver for synthetic data. These are just a few of the many ways that Language Studio creates new data assets that bolsters your own custom machine translation engine.
