CAT Pane in Phrase TMS

Watch this webinar about the CAT Pane and the resources available in Phrase TMS (Terminology Bases, Translation Memories, Machine Translation and non-translatable matches)

The Computer Assisted Translation (CAT) pane displays segmented source text alongside matches from translation memories, term bases, and machine translations after pre-translation. Non-translatable matches are also displayed. Double click on the suggestion to apply it to the target text.

To see more information about a segment in the lower window, click on the segment in the CAT pane.

Hovering over information in the bottom window provides more detail.


CAT results are displayed in the following order and are color coded:

  1. Green - Best translation memory or non-translatable match, based on the score.
  2. Yellow - Term base items (If there is a preferred term, it will be placed at top.)
  3. Orange - Translation memory, non-translatable, or MTQE based on scores.
  4. Blue - Machine translations (with no MTQE score).
  5. Pink - Sub-segment TM (S).

How similar the new source is to what is in the Translation Memory:

  • 101% - An in-context translation memory match.A greater than a 100% match indicates the context also matches what is saved in the TM.
  • 100% - An exact translation memory match.
  • 78% - A fuzzy translation memory match (anything below 100%).
  • S - A subsegment match.If a smaller part of the original text was previously translated as a short segment, the CAT pane will display it even though the match is lower then the threshold set in the Editor’s Preference.

Term Base matches

  • TB indicates a suggested term from a term base.
  • TB in grey indicates a New term that has not yet been approved.
  • A term in red indicates a term that has been rejected and should not be used during translation.

When a term is selected, details are displayed at the bottom of the pane.

Machine Translation matches


  • 100%: Perfect MT output - post-editing likely not required.
  • 99%: Near-perfect MT output - minor post-editing required; likely formatting or punctuation issues.
  • 75%: Good MT match, some human post-editing required.
  • No score: MTQE cannot confidently identify the quality. Output should be checked by a Linguist.

What is a translation memory or TM?

A database consisting of original source text and its respective translated segments.
It works by automatically reusing any segments that are the same or similar on new projects.
The more our community translates, the more this database grows, and the higher the chance is of finding translation memory matches.

What is a Term Base or TB?

A term base is a terminology database. It includes glossaries.

Hello. I have just watched the excellent Memsource video you produced for us. My question is, when I start translating the CAT pane tells me there are no resources for TM, TB and MT.
Can you help me? This is my first task and I am keen to get it 100% correct!
Many thanks


Hi @Penelope

I’m glad you found the Memsource webinar useful :star_struck:

If you can’t see any resources for the TM, TB and MT then unfortunately it means we haven’t got any for that project.

We are working on increasing the number of resources available to assist translations and this will also increase as more translations are completed using Memsource!

You can always reach out to the project manager by posting on the project thread as they may have more information for you :+1:

Thanks for reaching out on this, Penelope :smiley:


Charlotte, thank you. It was late and I was tired - I should have worked that out for myself!

No problem @Penelope!

We’re always here to help! So feel free to ask any questions on the forum, as it’s better than struggling alone :hugs:


Hello, I received in my email a text to translate from English to Portuguese. I would like what is the link to use the Memosource and how can I get the texto to translate.

Thank you,

Hi @javis

Firstly, welcome to TWB!

I’ve moved your comment to this thread which has more information about the CAT pane in Memsource :+1:

If you take a look at the post at the top of this thread, it explains what the numbers mean :smiley:

I hope this clears things up for you, Chaouki!

Hi @javis

I’m glad the information in this post was useful!

The numbers don’t change, they simply tell you how much of a match the translation memory is :smiley:
