Keeping terms consistent
A field's terms are where a translated paper most often goes wrong. How to build a term list, choose the English, and check that one idea stays one term from the abstract to the conclusion.
A reader in your field forgives an awkward sentence. They notice when a term changes. If a concept is called one thing in the abstract and another in the discussion, they will wonder whether you mean two different things.
Why terms drift
Most words have more than one acceptable translation. A general translator picks whichever fits the sentence in front of it, and the next sentence may get a different choice. Across a dissertation of tens of thousands of words, the same term can come out three or four ways. Each one is defensible. Together they read as confusion.
Build the list before you translate
Go through the original and write down every term that matters: methods, instruments, measures, named concepts, and anything your field uses in a specific sense. Include abbreviations, and whether each should be expanded in English on first use.
Take the English from your field
For each term, find the English that published work in your field uses. Search recent papers in the journals you read, and check a review article or a standard textbook. A general dictionary gives the common meaning, which is often not the technical one.
Where the field has no settled English, choose one and keep it. Say so in a footnote if a reader might expect another.
One idea, one term
Use the same English for the same concept everywhere: in the abstract, the headings, the tables, the figure captions, and the conclusion. When two terms in the original really do mean different things, make sure the English keeps them apart.
Check it beside the original
Read the English beside the original and look for each term where it appears. A search of the English for the alternatives you rejected will find the places it slipped.
How Tolayda handles it
Tolayda keeps a glossary for each source language. Every paragraph is translated with the glossary terms it contains, and every glossary term must appear in the English. When a passage comes back without one, it is translated again. A glossary exported from DeepL as CSV imports as it is.
The English then sits beside the original, block by block, so a term can be checked where it occurs and corrected with a click. More on how that works is on the Why Tolayda page, and on the wider process in Translating a dissertation into English.
