Hello,

I would like to know which CAT tool would best help me translate high level mathametical book. I'm particularly concerned about the symbols and equations. Which CAT tools would help me preserve the complex math symbols and equations.

Thanks in advance

Unicode Apr 28

Modern CATs support Unicode for special chars, so it's not a problem.

However, what exactly your issue: LaTeX? MS Word formulae? Or something else?
We never translated equations, often marking them as untranslatable or saving it as pictures to prevent editing.

Copying and pasting the equations from original to translated version Apr 28

I translated a lot of math content with the help of MATE cat; however, when it downloads my translation as a Microsoft Word document, I lose all the equations. Then when I try to copy the equations from the original PDF in Adobe and paste them into the translated document (whether it is doc or pdf), it simply does not work. I have to include the equations, symbols and graphs in the translated version. Since MATE cat does not reproduce the equations, how can I copy them from the original docume... See more

Something that appears so simple is presenting a lot of difficulties for me.

not a CAT issue Apr 28

I'm afraid, it's not a CAT only issue, because (1) a PDF is mostly a DTP product not intended for editing and (2) there's no 100% equivalence between any different formats.

We used clean snapshots/pictures, adding relevant tags for searching.

The problem with editable equations is rather searchable and still not really solvable for the only almost* sure-fire way to copy a formula from one format to some other is... recreating the formula, alas.

Probably no CAT solution Apr 28

From your description, you appear to be working with pdf files the source of which which may have been created either via DTP or by distilling from Word. The embedded equations are images which do not lend themselves to translation by CAT tools, as another poster has indicated. In such cases, I've used the "snapshot" feature of Adobe Acrobat (available in older editions, I can't say whether it's currently available) to copy and paste the original equation into my target document (indicated by a ...

In such cases, I've used the "snapshot" feature of Adobe Acrobat (available in older editions, I can't say whether it's currently available) to copy and paste the original equation into my target document (indicated by a dummy placeholder in the translation). I'm surprised this hasn't worked for you.
When working with Word documents with embedded equations (created in Word), I've sometimes had success with MemoQ.

I suspect that you will have to use an equation editor to recreate your equations. Until relatively recently, this was a module in MS Word. There are commercially-available equation editors available, and, for all I know, freeware/shareware products as well.
Good luck!

Copy and pasting equations Adobe Apr 28

Thanks for your guys' input and suggestions.

I have attempted to use Adobe's snapshot feature; unfortunately, it was to no avail. I first used it to paste the equations into the translated doc file. It did work for a few equations, but for most, it did not. I also attempted to use the snapshot to copy and paste from the original PDF file into the target file (which I converted to PDF) and that did not work at all.

Should I request that the orginal file be in DOC format?

Should I request that the orginal file be in DOC format? Wouldn't that resolve the problem of having to reproduce all of the equations and graphs on my own?

Word doc might be a solution Apr 29

If your client is an agency, you might not get the source DOC file, but it wouldn't hurt to ask, especially since I have the impression that this is a long file. It may be that the equations are also images, but if they are, they should be easier to copy into your target file.

I find it odd, however, that the client has requested a pdf file. Normally a translation is checked by another set of eyes, and Word documents are easier to edit. I know that clients sometimes want a pdf anyway, but they're harder to edit.

Use a PDF to DOC converter Apr 29

Not mainly for the the text in this case, but chiefly to capture the equations in a Word environment. For this, you should set the conversion parameters (settings) so that embedded images are not converted by OCR. I use Nuance Power PDF, which I find to be the most useful software for this purpose. I run Windows 7 on a 64-bit Dell machine. I have yet to explore the capabilities of Studio 2019 for handling equations, although I suspect that compiling each from scratch is lengthy and, in any case,... See more

I hope this helps.

With kind regards,

What is the original format? Apr 29

PDF is, itself, an export format. If you wish to retain the equations, you may have to figure out what the original format was, and then translate the original file (the file that was used to generate the PDF file from). Do you know what the original format is, and do you have access to files in the original format? Or did the client just send you PDFs and expected you to deliver formatted DOC(X) files in return?

It is entirely possible that despite all your efforts to reproduce the equations in DOC(X) format, the client's DTP officer is simply going to ignore it and retain the equations that are already in the original file (and attempt to update the translatable bits of it). In other words, the client isn't going to send your DOC(X) file to the printers; instead, her DTP officer will copy/paste text from the DOC(X) file into their own DTP software. Ask the client if it would be okay for you to just refer to the equations using textual descriptions, and/or by pasting screenshots of it.
