A Translation Memory (TM) is a database of previously translated text. This text is split into smaller segments (usually sentences or titles) in a process called Segmentation. The original segment and its translation are then saved into translation memory as a 'translation unit'. The TM can have several target languages (the source language can be only one) and can be used in multiple projects simultaneously.
Using TMs has two benefits:
- Translators can reuse translations which speed up the translation process and reduces costs.
- TMs also help to ensure that translations are consistent, especially when, for example, different translators are working on the same project for a specific client.
Setting up a translation memory
- First, you have to create a new translation memory
- You can then assign this memory to a Memsource project, so the ongoing translation will be saved there
- You can import a TMX from another CAT tool or special Excel file into your Memsource TM
- You can align previously translated text with its original version and import it into Memsource TM
- You can edit the parameters of the TM
- You can search and edit the content of the TM directly in Memsource Cloud
- Or you can export it and edit it outside the Memsource or import it into another CAT tool
Using a translation memory
Once the TM is ready and contains some saved segments, you can use it for:
- Analysis of the jobs - to see if there are any matches between your job and your TM
- Pre-translate your job in a batch
- Display/insert matches from TM to your linguists in the Memsource Editor during the translation process.
While there are no specific limits to how many target languages the TM can have or how many translation units can be saved into TM, please bear in mind that very large TMs (with millions of segments) can slow down the performance of search, pre-translation or analysis and can be difficult to maintain and edit. There is also a limit to a file size (1 GB) for export and import. A project can have multiple TMs, so it is better to have a few smaller TMs then a very large one.
