Build and manage training documents
Custom Translator enables you to build translation models that reflect your business, industry, and domain-specific terminology and style. Training and deploying a custom model is easy and doesn't require any programming skills. Custom Translator allows you to upload parallel files, translation memory files, or zip files.
Parallel documents are pairs of documents where one (target) is a translation of the other (source). One document in the pair contains sentences in the source language and the other document contains those sentences translated into the target language.
Before uploading your documents, review the document formats and naming convention guidance to make sure your file format is supported by Custom Translator.
How to create document sets
Finding in-domain quality data is often a challenging task that varies based on user classification. Here are some questions you can ask yourself as you evaluate what data may be available to you:
Enterprises often have a wealth of translation data that has accumulated over many years of using human translation. Does your company have previous translation data available that you can use?
Do you have a vast amount of monolingual data? Monolingual data is data in only one language. If so, can you get translations for this data?
Can you crawl online portals to collect source sentences and synthesize target sentences?
Training material for each document types
|Source||What it does||Rules to follow|
|Bilingual training documents||Teaches the system your terminology and style.||Be liberal. Any in-domain human translation is better than machine translation. Add and remove documents as you go and try to improve the BLEU score.|
|Tuning documents||Trains the Neural Machine Translation parameters.||Be strict. Compose them to be optimally representative of what you are going to translation in the future.|
|Test documents||Calculate the BLEU score.||Be strict. Compose test documents to be optimally representative of what you plan to translate in the future.|
|Phrase dictionary||Forces the given translation 100% of the time.||Be restrictive. A phrase dictionary is case-sensitive and any word or phrase listed is translated in the way you specify. In many cases, it's better to not use a phrase dictionary and let the system learn.|
|Sentence dictionary||Forces the given translation 100% of the time.||Be strict. A sentence dictionary is case-insensitive and good for common in domain short sentences. For a sentence dictionary match to occur, the entire submitted sentence must match the source dictionary entry. If only a portion of the sentence matches, the entry won't match.|

Document set nameand select Browse files to select source and target documents.
- For Translation memory (TM) file or Upload multiple sets with ZIP, select Browse files to select the file
- For Parallel documents, fill in the
At this point, Custom Translator is processing your documents and attempting to extract sentences as indicated in the upload notification. Once done processing, you'll see the upload successful notification.
View upload history
In workspace page you can view history of all document uploads details like document type, language pair, upload status etc.
From the Custom Translator portal workspace page, click Upload History tab to view history.
This page shows the status of all of your past uploads. It displays uploads from most recent to least recent. For each upload, it shows the document name, upload status, the upload date, the number of files uploaded, type of file uploaded, the language pair of the file, and created by. You can use Filter to quickly find documents by name, status, language, and date range.
Select any upload history record. In upload history details page, you can view the files uploaded as part of the upload, uploaded status of the file, language of the file and error message (if there is any error in upload).
